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.

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 Ice weaknesses, apply DEF Debuff to you, 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, it's recommended to use Repel Almighty Magic (such as from Huang Long) or Spirit Chains of Intimidation (such as from Lost Name). If neither is available, go all-in on attack.
  • Repel Almighty Magic 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.
    • Heimdall doesn't have Phys Pierce, so Demons with innate Null/Repel/Drain Phys or a Null Phys transfer can wall Heimdall's standard attacks and his enrage.
      • 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.
  • 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.

Underside skill demons

Baphomet

Baphomet (Underside) effect overview

• Self gets 50% HP, 180% Fire damage, 20% accuracy, 3 MP discount for Fire skills, and immunity to Spirit Chains of Suppression.
• The team gets 20% Fire damage and 20% accuracy.
• If any team member hits a weak point, Baphomet restores 2 MP to the whole team (up to 3 times per turn).

Colors

• Clear for the fusibles ruleset. The other colors don't offer anything useful for a Fire build.

Skill Transfer

• Trisagion (Underside) is ideal, otherwise use the highest-damage single-target attack skill you have. For example: Trisagion.
• Agidyne works as a cheap alternative.
• His innate Maragi can be leveled cheaply by transferring it from 2★.

Brands

• MATK% Spell.
• Due to his MP discount and MP restores (counteracting the enemy's MP drains), Divine's MP regen is probably not necessary.

Jack Frost

Jack Frost (Underside) effect overview

• Self gets Concentrate (2.25x damage) on his first action - this is about 63% damage on average across his 2 actions on the first turn. Also gets 50% HP and immunity to Spirit Chains of Suppression.

Colors

• (Any)

Skill Transfer

• Use Agidyne.
• Jack Frost does not have any MP discounts, so 7 MP skills such as Trisagion may be too expensive to cast repeatedly.
  • Trisagion (Underside) starts at 7 MP, then becomes 6 MP at max level. This is the best skill he can use, but the cost of maxing it is very high.

Brands

• MATK% Spell or Divine.

Misc notes

• If using Trisagion (Underside), then Concentrate only affects the initial hit, not the AoE chain.
• Consider transcending him for skill switches, as that lets him easily swap builds between multiple areas.
