Team notes:

Asura: 212 strength, 30% crit rate, P1 has 20% crit rate, P3 has 30% random-target damage aura. Ashura (50 power AoE w/ 50% crit + 250 power random w/ 80% crit). Using Ashura also removes all enemy buffs, and panel 4 removes all debuffs on your party. Needs Resist Ice.
- He's also the fastest unit in this team, so he has Tetra Break transferred.
Shiva: 229 strength, has Serial Killer, P1 has 15% damage. Has 20% crit rate, P2 has 20% crit, P4 has 50% crit. Standard attack is 0 MP Vorpal Blade (140 power AoE). Red has God's Hand (200 power single). Standard attack is free and God's Hand is 5 MP if P3, so he won't have MP problems and can safely run War brands.
- Shiva can also remove the enemy's Repel Physical by using Pralaya, but that won't trigger Koumokuten's bonus effects.
Flauros: 192 strength, P3 gives 15% phys damage, Purple has Epitome of Carnage. Iron Fist grants EVAC Buff ATK and EVAC buffs, complementing Koumokuten's debuffs.
Seth: 248 strength, p1 has 15% damage, p4 has 25% damage. Ouas (160 power single-target with 50% crit). P3 makes Ouas cost 4 MP, so he shouldn't have MP problems and can run War brands.
Koumokuten with his underside skill provides a 20% Phys damage and 50% accuracy aura to the team, and when a team member uses Tetra Break, he reacts with DEF and EVAC debuffs, plus a Phys hit directed at the boss.
- Koumokuten actually has Tetra Break innately, so he could theoretically trigger his own bonus effects. However, his base agi is so low that getting him to the front of the party may be difficult.
- His colors don't offer very much, so we opt to run him in Clear to fit multiple rulesets.
- Cheap to build by using 3★ to get skill points (4 SP for a Koumokuten dupe, or 1 SP for any other 3★). You can level his Hades Blast by transferring it from Ose dupes.
- He also has a 3 MP discount for Phys skills, meaning he should not have MP problems and can safely run War brands. This also means he can safely use powerful high-MP attack skills such as God's Hand, but cheaper options such as Oni-Kagura can also work. Giving him Struggle Slash (Underside) would be ideal, should you pull one from the random cubes.
Ice weaknesses are covered on everyone, to prevent Hresvelgr from setting off a death combo.

Other options worth considering:

Cu Chulainn: 201 strength, P1 has 20% damage, P3 has 20% damage, P4 has 25% damage. Has 100% crit rate at P4. Gae Bulg (400-600 power random). However, he will have accuracy issues if not panel 4.
Cerberus: 170 str, P3 gives a 20% phys damage aura, 20% all-damage to Beast race, and 50% crit to self. Hell Claw (420 power random w/ 50% crit). War Cry for ATK and DEF Debuffs, and Yellow has War Dance for ATK and DEF Buffs. Hell Claw also applies Spirit Chains of Intimidation to help survival. Needs Resist Ice.
Gogmagog: Good damage based on PDEF, and has Repel Ice for 30% Ice damage reduction. May have accuracy issues if you don't have Koumokuten Underside, though.
Titan: Good damage based on PDEF.
Odin: 176 str, P3 gives 10% phys damage, Clear has Merciless Blow. Gungnir (145 power AoE w/ 30% crit). He's expensive to panel, however.
Wu Kong: 235 str, has Phys Boost, P3 gives 10% phys damage, P2 gives 10% crit. Titanomachia (125 power AoE w/ 30% crit) and Oni-Kagura (135 power single w/ 30% crit).
Girimekhala: 216 str, P3 gives 10% phys damage. Megaton Press (105 power AoE w/ 30% crit) and Binge Eating (140 power single). Mega Boost gives himself both Charge and Might.
Hanuman: 223 str, P3 gives 10% phys damage. Vorpal Blade (140 power AoE) and Madness Nails (130-195 power random). Can be re-used for the race challenge.
Yatagarasu: 184 str, P3 gives 10% phys damage, Clear has Phys Boost. Hades Blast (120 power AoE). Needs Resist Ice.
Valkyrie: 196 str, has Phys Boost. Heat Wave (85 power AoE w/ 10% crit), Fatal Sword (100 power single).
Fomorian: 183 str, Clear has Back Attack. Herculean Strike (100 power AoE). Can be re-used for the race challenge.

Race challenge

Team restrictions:

Difficulty	Restriction
Lv 3-5	All 5 demons must be of the races Genma, Kishin, Night, Drake, or Tyrant.
Lv 6-8	All 5 demons must be of the races Genma, Kishin, Night, or Drake.
Lv 9+	All 5 demons must be of the races Genma, Kishin, or Night.

General strategy:

Transfer Tetra Break to your fastest unit, and have them cast it when the fight starts to remove the enemy's shield.
After the shield is down, spam Phys attacks to hit the enemy's weaknesses. Try to ensure Tsukuyomi dies quickly, so he can't re-cast the shield.
Try to bring demons that can counteract the initial Luster Candy and Debilitate. There is a decent chance your attacks will miss the boss if the enemy still has a full EVAC swing in their favor.
If you have a Koumokuten with the skill Koumokuten (Underside), bring him.
Cover your Ice weaknesses, to prevent Hresvelgr from killing anyone. If he gets a kill, he re-casts his shield and casts a North Wind AoE. This can quickly snowball into a long combo of North Winds that can wipe your team.

Team notes:

Marici: 195 str, Daylight Blade (200 power single w/ 50% crit). P1 and P2 give accuracy and crit dmg aura. She has 2x Lead set effects to put her in the first spot (otherwise Fionn would be first), and she has Tetra Break to remove the shield ASAP.
Fionn mac Cumhaill: Very high damage, applies Zenith with Moon-White Blade, and casts one ATK Buff for 1 turn at start of combat.
Futsunushi: Team-wide Might on the first turn, then he can spam Iai Isshin which grants him Charge with every cast.
Cu Chulainn: 201 strength, P1 has 20% damage, P3 has 20% damage, P4 has 25% damage. Has 100% crit rate at P4. Gae Bulg (400-600 power random). However, he will have accuracy issues if not panel 4.
Koumokuten with his underside skill provides a 20% Phys damage and 50% accuracy aura to the team, and when a team member uses Tetra Break, he reacts with DEF and EVAC debuffs, plus a Phys hit directed at the boss.
- Koumokuten actually has Tetra Break innately, so he could theoretically trigger his own bonus effects. However, his base agi is so low that getting him to the front of the party may be difficult.
- His colors don't offer very much, so we opt to run him in Clear to fit multiple rulesets.
- Cheap to build by using 3★ to get skill points (4 SP for a Koumokuten dupe, or 1 SP for any other 3★). You can level his Hades Blast by transferring it from Ose dupes.
- He also has a 3 MP discount for Phys skills, meaning he should not have MP problems and can safely run War brands. This also means he can safely use powerful high-MP attack skills such as God's Hand, but cheaper options such as Oni-Kagura can also work.

Skills on Heimdall only:

Skills on King Frost only:

Explanation

Hellbound: Phys will apply 5 stacks of Spirit Chains of Suppression to you.
Hell Eater drains your MP whenever your turn starts, and King Frost will drain your MP with Cold World Underside when he attacks (as well as applying ). When Heimdall falls below 50% HP, his Stout Horn Underside will also start draining your MP.
If you fail to kill the adds by the start of their second turn, they will hit you with a bulwark-piercing, 100%-crit enrage AoE. Heimdall will do one too, if he isn't dead by his third turn - however his lacks phys pierce, so it can be reflected back at him with Repel Physical.

Fusibles challenge

Team restrictions:

Difficulty	Restriction
Lv 3-5	3 or more demons must be fusible*.
Lv 6-8	4 or more demons must be fusible.
Lv 9+	All 5 demons must be fusible.
Lv 6+	1 or more demons must be grade 79 (4★ base) or lower.
Lv 9+	1 or more demons must be Clear.

Notes regarding fusibles:

Multi-fusions count.
- Beelzebub☆ counts, despite needing a gacha-exclusive material to make him.
- The following limited-time multi-fusions count: Masakado A, Alice A, Asura, Indrajit. All other limited-time multi-fusions do not count.
Pixie and Slime count, even though you cannot fuse them.

General strategy:

Your primary objective is to kill King Frost with Fire attacks on the first turn. If you don't, then he will hit into your weaknesses (most fusible Fire attackers are weak to Ice), debuff your defense, and steal all your MP. The Mandrakes should go down easily afterwards, allowing you to isolate Heimdall.
MP management is very tight in this fight, consider running Divine brands on as many demons as possible.
If you have a Baphomet with the skill Baphomet (Underside), bring him.
For survival, have Huang Long use Five Elements ( Repel Almighty Magic), which will stop Heimdall from using his unique Almighty attack. Now, Heimdall will resort to standard attacks.
- If possible, have Huang Long at panel 4 for his magic damage aura (+20% magic dealt and -20% magic received for the party while under Repel Magic). In this case, cast Five Elements ASAP to help push damage against King Frost.
Consider bringing demons with innate Null/Repel/Drain Phys, or a Null Phys genome transferred. Heimdall doesn't have Phys Pierce, so as long as Repel Almighty Magic is active, he will be unable to attack anyone that blocks Phys. This applies to both his standard attacks and his enrage AoE, which are both Phys.
- Example 5★ demons with innate NDR Phys: Teal Quetzalcoatl, Teal Gogmagog, Zaou-Gongen, Erlkonig, Fafnir, Masakado A, Beelzebub☆
- Example 4★ demons with innate NDR Phys: Girimekhala, Rangda, Hecatoncheires, Teal Wu Kong
If you cast Tetrakarn or use a Phys Reflector (for Repel Physical) just before Heimdall's enrage, then you can reflect it back at him, potentially dealing a lot of damage to finish him off. However, you cannot have both Repel Physical and Repel Magic active at the same time, so only take this chance if you are sure the reflect will kill Heimdall. If Heimdall survives, then he will be free to use his Almighty attack, and might kill you.

Team notes:

Everyone should have Divine brands, due to the tightness of MP in this fight.
Huang Long for Repel Almighty Magic and his panel 4 magic damage aura. Yellow can also buff with Luster Candy to push more damage. He should go first in the party, so he can activate his magic damage aura ASAP.
Cybele satisfies the Clear requirement, offers a team Fire damage aura (10% at base, 20% at p3), and has good innate Fire skills.
Metatron for his panel 3's 20% magic damage aura. He also has Maragidyne so he can contribute his own damage.
Surt pushes damage against King Frost.
Baphomet with his underside skill gives a 20% Fire damage and 20% accuracy aura, and whenever a teammate hits an enemy's weakness, everyone on your team recovers 2 MP (up to 3 times per turn). This helps counteract the enemy's MP drains.
- His colors don't offer very much, so we opt to run him in Clear to fit multiple rulesets.
- He also has a 3 MP discount for Fire skills, meaning he should not have MP problems and can safely run Spell brands. This also means he can safely use powerful high-MP attack skills such as Trisagion, but cheaper options such as Agidyne can also work. Giving him Trisagion (Underside) would be ideal, should you pull one from the random cubes.
Remember to use Tetrakarn or use a Phys Reflector just before Heimdall does his Phys enrage!

Other options worth considering:

Cerberus: 170 str and 150 mag, P3 gives a 20% phys/fire damage aura, 20% all-damage to Beast race, and 50% crit to self. Agidyne. War Cry for ATK and DEF Debuffs, and Yellow has War Dance for ATK and DEF Buffs. Hell Claw also applies Spirit Chains of Intimidation to help survival.
Prometheus: 226 magic, has Fire Boost, p3 has 10% fire damage. Agidyne and discounted Maragidyne. Purple is also an option, swapping out the Maragidyne for Infinite Chakra.
Anubis: 217 magic, Purple has Merciless Blow. Transfer Agidyne + Fire Boost.
Titania: 235 magic, Purple has Back Attack. Transfer Agidyne + Fire Boost.
Efreet: 208 magic, has Fire Boost, Purple has Back Attack. Maragi and Agilao. Alternatively, can use Clear for discounted Agidyne.

Race challenge

Team restrictions:

Difficulty	Restriction
Lv 3-5	All 5 demons must be of the races Beast, Vile, Femme, Tyrant, or Godly.
Lv 6-8	All 5 demons must be of the races Beast, Vile, Femme, or Godly.
Lv 9+	All 5 demons must be of the races Beast, Vile, or Tyrant.

General strategy:

Your primary objective is to kill King Frost with Fire attacks on the first turn. If you don't, then he will hit into your weaknesses, debuff your defense, and steal all your MP. The Mandrakes should go down easily afterwards, allowing you to isolate Heimdall.
MP management is very tight in this fight, consider running Divine brands on as many demons as possible.
If you have a Baphomet with the skill Baphomet (Underside), bring him.
The featured races do not have access to Repel Almighty Magic, so you'll need to use a different method to survive Heimdall's Almighty attack spam. For example: Spirit Chains of Intimidation.
If you cast Tetrakarn or use a Phys Reflector (for Repel Physical) just before Heimdall's Phys enrage, then you can reflect it back at him, potentially dealing a lot of damage to finish him off.
- However, if you plan to do this, make sure Heimdall doesn't have any stacks of Intimidation, as those will reduce the power of the reflected damage.

Team notes:

Lost Name is easily accessible, does good damage based on HP, and applies Spirit Chains of Intimidation to help the team survive. His panel 1 helps significantly, dropping the cost of Fatal Burn to just 4 MP at max skill level.
Moloch: Does decent damage based on HP, and provides a 40% Fire damage aura.
Surt A: 201 magic, has Fire Amp and 20% damage, P3 gives 25% damage. Eruption (120 power AoE + ramping 100-175 power random). Applies DEF Debuff when Eruption is used. Panel 2 can also change his Standard Attack into magic, allowing him to attack without needing MP.
Baphomet with his underside skill gives a 20% Fire damage and 20% accuracy aura, and whenever a teammate hits an enemy's weakness, everyone on your team recovers 2 MP (up to 3 times per turn). This helps counteract the enemy's MP drains.
- His colors don't offer very much, so we opt to run him in Clear to fit multiple rulesets.
- He also has a 3 MP discount for Fire skills, meaning he should not have MP problems and can safely run Spell brands. This also means he can safely use powerful high-MP attack skills such as Trisagion, but cheaper options such as Agidyne can also work. Giving him Trisagion (Underside) would be ideal, should you pull one from the random cubes.
The remaining members are just whatever Fire users are available.
Remember to use Tetrakarn or use a Phys Reflector just before Heimdall does his Phys enrage!

If you have a Baphomet with the skill Baphomet (Underside), bring him.
Compared to the other rulesets for this area, we don't have defensive utilities like Repel Almighty Magic or Spirit Chains of Intimidation - but we do have a lot more offensive power to work with. So the strategy here is to simply win by brute force!
If you cast Tetrakarn or use a Phys Reflector (for Repel Physical) just before Heimdall's Phys enrage, then you can reflect it back at him, potentially dealing a lot of damage to finish him off.

Also, if he dies, then he will revive himself on your turn, cleansing off his own Spirit Chains of Suppression (since that disappears upon death), and casts a 1-turn Luster Candy. If he dies a second time, he will repeat this, on top of granting bulwarks and healing to the team.

Cerberus: 170 str and 150 mag, P3 gives a 20% phys/fire damage aura, 20% all-damage to Beast race, and 50% crit to self. Agidyne. War Cry for ATK and DEF Debuffs, and Yellow has War Dance for ATK and DEF Buffs. Hell Claw also applies Spirit Chains of Intimidation to help survival.
Surt A: 201 magic, has Fire Amp and 20% damage, P3 gives 25% damage. Eruption (120 power AoE + ramping 100-175 power random). Applies DEF Debuff when Eruption is used. Panel 2 can also change his Standard Attack into magic, allowing him to attack without needing MP.
Agni: 207 magic, has Fire Boost, P1 has 5% damage. Maragion. Purple applies DEF Debuff at start of combat.
Anubis: 217 magic, Purple has Merciless Blow. Transfer Agidyne + Fire Boost.

Skills on Mithras only:

Skills on Cybele only:

Explanation

Hellbound: Fire will apply 5 stacks of Spirit Chains of Suppression to you.
If you fail to kill the adds by the start of their second turn, they will hit you with a bulwark-piercing, 100%-crit enrage AoE. Mithras will do one too, if he isn't dead by his third turn.
Mithras will follow up with Covenant Bless Underside whenever he, his allies, or you use a Fire/ Light attack. The hit doesnt hurt, but it does heal Mithras and his party, which can prolong the fight. Cybele and the Shiki-Ouji on the right also have healing spells.

Low-grade challenge

Lv 9+	2 or more demons must be grade 79 (4★ base) or lower.
Lv 9+	1 or more demons must be grade 59 (3★ base) or lower.

General strategy:

Bring as many Ice attackers as possible, and kill the adds first so they can't heal Mithras.
If you have an Illuyanka with the skill Illuyanka (Underside), bring that, as it trivializes this fight.

Team notes:

Illuyanka's contribution mainly comes from his 80% Ice damage aura and his Ice AoE chain.
- He also has a 3 MP discount for Ice skills, meaning he should not have MP problems and can safely run Spell brands. This also means he can safely use powerful high-MP attack skills such as Ice Age or Ice Age (Underside).
- We're using Clear so Illuyanka can be used in multiple rule sets. This happens to give him Bufudyne, meaning the other transfer slot should be a damage booster.
- A small optimization is to build a Purple Illuyanka for the +10 magic from Magic Amp II. His transfer should be Ice Age.
- If you happen to pull Ice Age (Underside) from the random cubes, use that regardless of color (with Purple performing slightly better than Clear).
- Cheap to build by using 3★ to get skill points (4 SP for an Illuyanka dupe, or 1 SP for any other 3★). You can level his Ice Breath by transferring it from Mermaid or Illuyanka dupes, and can level his Bufudyne by transferring it from Orochi dupes.
King Frost provides DEF Debuff via his skill Cold World, to help push the damage. We also give him Auto-Taruka for ATK Buff, ensuring we have a full offensive buff swing. Teal covers his weakness.
The rest of the team are just Ice attackers that don't have open weaknesses to Fire or Light, to ensure Mithras can't get extra turns off them. Resist Fire or Resist Light can be transferred to patch weaknesses, if needed.

Other options worth considering:

Kumbhanda: Deals high-crit physical Ice damage, and applies Spirit Chains of Corrosion to increase the team's DPS.
Beiji-Weng: 186 magic, has Ice Boost and P3 has 10% Ice damage. Bufudyne and Mabufudyne. Will need Resist Fire.

Skills on multiple demons:

Skills on left Jatayu only:

Skills on Fafnir only:

Skills on Orochi only:

Skills on right Jatayu only:

Explanation

Hellbound: Phys will apply 5 stacks of Spirit Chains of Suppression to you.
Fafnir starts the battle by casting a 1-turn DEF Buff and EV/AC Buff.
The enemy starts each turn with various effects in this order: Curse from the left Jatayu, Weak from the right Jatayu, Barrier Break from Orochi, and finally Poison from Orochi.
- Due to this order, the Jatayus' ailments can be blocked by Barrier (such as from Ward brands), but Orochi's ailment cannot be blocked.
- The ailments have +350% inflict chance, meaning they are effectively guaranteed to land if not blocked by Barrier or an immunity.
Fafnir's passive makes you take +1500% damage per tick of Poison (effectively 16x, or 80% of your max health), and applies 150% reverse damage boost per ailment that is on you.
If Orochi is hit by physical, magic, or fractional damage, then he will Poison the demon that attacked him (up to twice per turn).
Fafnir's Blight+ will inflict Poison to your team whenever he casts it.
If the adds are not dead at the start of their second turn, they will hit you with a bulwark-piercing, 100%-crit enrage AoE. Fafnir will do one too, if he isn't dead by his third turn.

Fusibles challenge

Team restrictions:

Difficulty	Restriction
Lv 3-5	3 or more demons must be fusible*.
Lv 6-8	4 or more demons must be fusible.
Lv 9+	All 5 demons must be fusible.
Lv 6+	1 or more demons must be grade 79 (4★ base) or lower.
Lv 9+	1 or more demons must be Clear.

Notes regarding fusibles:

Multi-fusions count.
- Beelzebub☆ counts, despite needing a gacha-exclusive material to make him.
- The following limited-time multi-fusions count: Masakado A, Alice A, Asura, Indrajit. All other limited-time multi-fusions do not count.
Pixie and Slime count, even though you cannot fuse them.

General strategy:

You need to cleanse off all the ailments before you can deal meaningful damage. This can be done with a cleanser, or by using an Amrita Shower.
- Dominion with the skill Dominion (Underside) will automatically cleanse all ailments.
- If you go with a cleanser, then note that the cleanser doesn't need to have any immunities. Ideally the cleanser should act first, allowing you to start dealing damage ASAP, and so nobody has to eat the massive Poison damage (80% of max HP).
- Among fusibles, cleansers need to rely on Prayer or Silent Prayer for cleansing, but those require pulling from the gacha to transfer them. Alternatively, a few fusibles have access to these skills innately:
  - Fusible demons with Prayer: Dominion, Titania
  - Fusible demons with Silent Prayer: Sarasvati, Asherah, Tiamat
Up to 2 times per turn, Orochi deals a revenge Poison to any demon that attacks him, which then immediately ticks for 80% of max HP. There are multiple ways to deal with this:
- Option 1: Bring Dominion with the skill Dominion (Underside), as he automatically gives Barriers to all team members, blocking the Poison.
- Option 2: Just eat the Poison damage, then cleanse it and heal the lost HP later. For efficient turn usage, use items in half-turns after hitting a weakness - one Amrita Shower to cleanse both attackers, then two Beads to heal the HP.
- Option 3: Kill Fafnir first, preferably with single-target attacks. Doing this will de-activate the increased poison damage and the DPS penalty while ailmented, making Orochi and the Jatayus into non-threats.
- Option 4: Transfer Null Poison to your first 2 attackers, meaning you don't take Poison damage at all. This is a gacha-exclusive skill, though. A few fusibles have it innately, but none of them are good at dealing Elec damage.

Team notes:

This team uses an Amrita Shower to cleanse the initial ailments.
After the ailments are dealt with, we just spam as much Elec damage as possible, with single-target damage directed toward Fafnir.
Indrajit provides ATK Buff and single-target Elec damage.
Anat provides ATK Debuff and DEF Debuff, as well as an Elec damage aura and a 1 MP discount for for the team's Elec skills. She also gets a free Concentrate on every second cast of Thunderstorm
Izanami provides an Elec damage aura, and another 1 MP discount for the team's Elec skills.
Dominion with his underside skill provides a 30% Elec damage and accuracy aura to the team, and when the first team member is about to act, he cures everyone's ailments and gives them Barrier. This saves you a press turn that would've been spent on cleansing, and the Barriers protect your team from Orochi's revenge Poison.
- Dominion himself is also immune to Curse, Poison, and Weak, meaning he won't get ailmented at all in this fight.
- We opt to run him in Clear to fit multiple rule sets. Alternatively, Red comes with Ziodyne.
- He also has a 3 MP discount for Elec skills, meaning he should not have MP problems and can safely run Spell brands. This also means he can safely use powerful high-MP attack skills such as Thunder Reign, but cheaper options such as Ziodyne can also work. Giving him Thunder Reign (Underside) would be ideal, should you pull one from the random cubes.

Other options worth considering:

Thor: 180 magic, P1 has 20% AoE damage, P3 has 40% Elec damage. Mjolnir (500 power random).

Skills on multiple demons:

Skills on Black Maria only:

Skills on Odin only:

Skills on right Berserker only:

Explanation

At the start of the player turn, Black Maria applies a 5% Bulwark to herself, and Odin applies an 8% Bulwark to the entire enemy team.
If Black Maria still has a Bulwark when your turn ends, she will hit your party with 50% Fractional Damage based on current HP. After that, she will remove Revive Ban from her entire team and revive them at full health.
- For every turn she is alive, the fractional damage will ramp up to use max HP instead, increase from 50% to 75%, and increase its damage cap to 5,000 and then 10,000 HP.
Black Maria's attacks are Almighty-based. Deathtouch heals her, while Sea of Chaos applies a 3-turn DEF Debuff to your party.
The left Berserker can sometimes apply Mute with Dark Sword.
Hellbound: Almighty will apply 5 stacks of Spirit Chains of Suppression to you.
If you fail to kill the adds by the start of their second turn, they will hit you with a bulwark-piercing, 100%-crit enrage AoE. Black Maria will do one too, if she isn't dead by her third turn.

Fusibles challenge

Team restrictions:

Lv 3-5	3 or more demons must be fusible*.
Lv 6-8	4 or more demons must be fusible.
Lv 9+	All 5 demons must be fusible.
Lv 6+	1 or more demons must be grade 79 (4★ base) or lower.
Lv 9+	1 or more demons must be Clear.

Notes regarding fusibles:

Multi-fusions count.
- Beelzebub☆ counts, despite needing a gacha-exclusive material to make him.
- The following limited-time multi-fusions count: Masakado A, Alice A, Asura, Indrajit. All other limited-time multi-fusions do not count.
Pixie and Slime count, even though you cannot fuse them.

General strategy:

You must break or remove Black Maria's Bulwark each turn, to avoid her revenge fractional hit and revives. The Bulwark is 13% of her max HP, 5% from herself and 8% from Odin.
- If you intend to break the Bulwark, then you must use attacks that do NOT pierce Bulwarks. Demons with Bulwark-piercing innate skills can consider transferring attacks that don't pierce, such as Zandyne or Wind Slash.
Once the Bulwark is down, kill Maria ASAP. The other enemies are not very threatening, so once Maria is down, the fight becomes trivial.

Team notes:

Garuda innately has Auto-Rakunda to apply DEF Debuff. We have Auto-Taruka transferred to apply ATK Buff as well, providing a full buff swing.
Cu Chulainn A's Barbed Spear pierces Bulwarks, which is unfortunate, as it cannot help break Maria's Bulwark. However, he still deals good damage to push for a kill.
- Transferring Wind Slash is an option, since it does not pierce Bulwarks.
- His color does not really matter.
Cu Chulainn: 190 magic, P1 has 20% damage, P3 has 20% damage, P4 has 25% damage. Mazandyne (120 power AoE).
Tsukuyomi is weak to Phys, so he has Resist Phys transferred to cover it.
- Damage-wise, he prefers using max-level Zanma plus a damage booster, over using Zandyne with no damage booster. Zanma can be leveled cheaply using 3★ fodder.
- His color does not really matter, unless you specifically need more HP from Purple.

Other options worth considering:

Inanna: Good Force damage, but her unique skills pierce Bulwarks. Mother Goddess's Fury can apply ATK Debuff and DEF Debuff to the enemy, while Red's Four Raging Calamities can apply ATK Buff and DEF Buff to your team.
Hariti: Good Force damage, but her unique skill Discipline pierces Bulwarks. That said, the skill also provides some MP and healing to the team whenever she casts it.
Garuda A: Good Force damage, but Gale Talon pierces Bulwarks.
Cybele: 202 mag and Merciless Blow. Will need a Force transfer, though. Note that her panels only affect Fire damage, so you can build a p0 copy for this (or, you can transcend an existing copy for skill switches).
Kurama Tengu: 134 mag. Zanma (140 power single).

Nastrond Underside - When an enemy dies, Nidhoggr gets a full heal and a 20% HP Bulwark. When your turn ends, a random enemy gets revived at 100% HP.
Yache Underside - When Ixtab is killed, she will deal 4 AoE hits of 10,000 fixed damage + Mortal, which also pierce Bulwarks and ignore endures. The gist is that she will wipe your party unless she dies last.
If the adds are not dead at the start of their second turn, they will hit you with a bulwark-piercing, 100%-crit enrage AoE. Ixtab will do one too, if she isn't dead by her third turn.

Fusibles challenge

Team restrictions:

Difficulty	Restriction
Lv 3-5	3 or more demons must be fusible*.
Lv 6-8	4 or more demons must be fusible.
Lv 9+	All 5 demons must be fusible.
Lv 6+	1 or more demons must be grade 79 (4★ base) or lower.
Lv 9+	1 or more demons must be Clear.

Notes regarding fusibles:

Multi-fusions count.
- Beelzebub☆ counts, despite needing a gacha-exclusive material to make him.
- The following limited-time multi-fusions count: Masakado A, Alice A, Asura, Indrajit. All other limited-time multi-fusions do not count.
Pixie and Slime count, even though you cannot fuse them.

General strategy:

Set up Evade Mortal (with Tetraja, for example) as soon as possible, and refresh it when it runs out. Make sure it's active to shield the revenge Mortal hit whenever you kill a Chatterskull.
- If you bring Arianrhod with the skill Arianrhod (Underside), then she will automatically cast Evade Mortal at the start of your turn.
Bring as many Light attackers as possible.
Focus on killing Nidhoggr first (preferably with single-target attacks), then kill the Chatterskulls, and kill Ixtab last.
- If Nidhoggr does not die first, then he will get a full heal and a 20% HP bulwark when each of the Chatterskulls die.
- If Ixtab is not killed last, then you will wipe.
- Do not simply AoE everything down! - if you try that, then the skulls will die first, Nidhoggr will heal + bulwark, then Ixtab will die, leaving Nidhoggr still alive, and you will wipe.
- Nidhoggr is also weak to Elec, and nobody NDR's it. Therefore, Elec AoE units can heavily damage Nidhoggr while only lightly damaging the other enemies.
Try to cover your Dark weaknesses, as Ixtab will spam Dark AoEs during her turn.

Team notes:

Arianrhod with her underside skill provides a 30% Light damage and 30% accuracy aura to the team, and automatically casts Evade Mortal at the start of your turn, saving you a press turn.
- She also has a 3 MP discount for Light skills, meaning she should not have MP problems and can safely run Spell brands. This also means she can safely use powerful high-MP attack skills such as Thunderclap.
- Her skill priority from greatest to least damage is: White Slash (Underside), Thunderclap (Underside), Thunderclap, Hamadyne, White Slash, innate Hamaon.
- However, using White Slash (Underside) or Thunderclap (Underside) is risky, as the AoE chain might kill the Chatterskulls before Nidhoggr.
- We're using Clear so Arianrhod can be used in multiple rule sets.
- She also has a healing boost. At level 50, maxed Media heals about 300 HP, while maxed Diara heals about 1400 HP. For comparison, Ixtab and the Chatterskulls deal about 500 damage per hit (with atk down + def up, but without Nu/Dr/Rp's 70% reduction), so Arianrhod's innate healing skills are unlikely to make a big difference. Stick with your healing items.
If you don't have Arianrhod, put Tetraja on your fastest unit, so you can cast it ASAP.
Anat: Deals a lot of AoE Elec damage, plus Thunderstorm applies ATK Debuff and DEF Debuff.
- The Spirit Chains of Suppression prevent Anat from wasting her Concentrate on her random-hit chain effect, meaning she can use it to spam every second Thunderstorm instead.
Anat and Izanami both boost the team's Elec damage, and grant a total 2 MP discount for the team's Elec skills.
Ishtar: Mesopotamian Star sets up buffs and debuffs (both for offense, and for helping survive Ixtab's attacks), then she can switch to using Mahamaon afterwards. Red offers Thunderclap as a single-target attack option.
All weaknesses to Dark are covered, to ensure the team survives Ixtab's first turn and then kills her on your second turn.
- This is technically optional with P3 Ishtar, as she's just bulky enough to be the sole survivor of the weakness spam (even with her own weakness open), and can then finish Ixtab. This will eventually stop working at around level 50, however, at which point you need the DPS from the team surviving to win.
From there, just use whatever Light units are available, with whichever damage boosters you have. Try not to boost your AoE damage too much, as to not kill Chatterskulls too early.
Despite Arianrhod's Light damage aura, this sample party goes for mostly Elec, since it can more-safely AoE everything down.

Other options worth considering:

Michael: 183 magic, P2 has 30% Light damage. However, Soul Judgement's random targeting can be a problem if it kills a Chatterskull too soon. Consider using him in Red for Thunderclap, or transferring Hamadyne.
Mastema: 201 magic, Purple has Light Amp and P1 has 15% Light damage. However, you may want to transfer Hamadyne since Trial of Hate is an AoE.
Anubis: 217 magic, Purple has Merciless Blow. Transfer Hamadyne + Light Boost.
Titania: 235 magic, Purple has Back Attack. Transfer Hamadyne + Light Boost.
Lailah: 206 magic, has Light Boost. Hamadyne and Mahamaon. Needs Resist Dark.
Sleipnir: 172 magic (p1), has Light Boost, P2 has 5% damage. Hamadyne and Mahamaon.
Principality: 195 magic, Purple has Light Boost. Hamaon. Needs Resist Dark.
Sandalphon: 170 magic (p1), P3 has 10% damage. Hamadyne and Mahamaon. Null Dark for 30% Dark damage reduction.

If you don't have Arianrhod, put Tetraja on your fastest unit, so you can cast it ASAP.
Zeus: Pushes a lot of single-target Elec damage on Nidhoggr. Also has Null Dark for 70% damage reduction.
Anat: AoE Elec damage with Thunderstorm, which also applies ATK Debuff, DEF Debuff, and Concentrate. If panel 2, also gives a 10% Elec damage aura and -1 MP cost of Elec skills for the team.
Izanami: AoE Elec damage, and a team Elec damage aura (20% if Panel 3, 10% if not). If panel 4, she also discounts the team's Elec skills by 1 MP. Also has Drain Dark for 70% damage reduction.
Ishtar: Mesopotamian Star sets up buffs and debuffs (both for offense, and for helping survive Ixtab's attacks), then she can switch to using Mahamaon afterwards. Red offers Thunderclap as a single-target attack option.
- Her weakness to Dark is covered, to ensure the team survives Ixtab's first turn and then kills her on your second turn.
At higher levels, note that this team can kill Nidhoggr with AOEs without killing the Chatterskulls. Once you've reached this point, it is not necessary to cast Tetraja on the first turn (since the skulls will not die), so you can squeeze in some more damage instead. Make sure to cast it on your second turn when you do expect the skulls to die, though.

Other options worth considering:

Odin A: Strong Elec attacker that applies Zenith and Gloom, as well as boosts the team's Elec damage, crit damage, and crit rate. However, note that his effect to prevent spending a press turn won't work, and he cannot gain boost levels on his skill while under Spirit Chains of Suppression.
Cleopatra: Good single-target Light damage, and applies Spirit Chains of Corrosion to reduce the bulk of all enemies. However, she will need a Resist Dark transfer.
Vishnu A: AoE Light damage. Also has Null Dark for 70% damage reduction. A small caveat is that his automatic Dark AoE will be repelled back at him, but it doesn't hurt very much.
Artemis: Good single-target Elec damage.
Norn: 193 magic, has Merciless Blow. Automatic cast of Luster Candy, and can do decent damage if given a Light or Elec transfer.
Sleipnir: 172 magic (p1), has Light Boost, P2 has 5% damage. Hamadyne and Mahamaon.
Sphinx: 210 magic, p3 has 10% light damage. Mahamaon and Ziodyne. Needs Resist Dark.
