Reverse damage reduction
Reverse damage reduction (no official name) refers to effects that apply a negative amount of damage reduction, causing the affected demon to take more damage. This is not the same as normal damage boosts.

Mechanics
Reverse damage reduction is applied at the end of the damage formula, where it is additive to normal damage reduction. For more details, see Damage Formula.
- Due to this, reverse reduction can directly counteract normal damage reduction.
- For example: if an enemy has a passive that grants -80% Elec damage taken, and your party has
Botis (applies +40% damage taken), then that partially cancels the enemy's passive (-80 + 40). This results in a total of -40% damage taken instead.
- For example: if an enemy has a passive that grants -80% Elec damage taken, and your party has
- Normal damage boosts (such as Elec Amp) cannot counteract damage reduction in any way.
Due to how the math works out, reverse damage reduction will result in higher damage output than an equivalent % of normal damage boosters.
- For example: Suppose
Elohim is in a party with 
Mithras. The 40% reverse reduction from Mithras's Covenant Bless results in more damage output than Elohim equipping 40% worth of damage boosts (such as Fire Amp (25%) + Fire Boost (15%)).
Skills that apply reverse damage reduction are usually phrased as affecting the damage the enemy takes/receives, rather than the amount of damage the party deals.
