Reverse damage reduction

Damage Received Increase, also called reverse damage reduction (RDR) or anti-damage reduction (ADR) by players, 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[edit]

Anti-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, anti-damage 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.
• Normal damage boosts (such as Elec Amp) cannot counteract damage reduction in any way.

Due to how the math works out, anti-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% anti-damage 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 anti-damage reduction are usually phrased as affecting the damage the enemy takes/receives, rather than the amount of damage your party deals. For effects that increase the damage your party deals, see damage boost.
