Critical Damage Boost

Critical Damage buffs and passive are boosts to damage upon dealing a critical hit, multiplying the overall damage by the total Critical Damage multiplier.

The base value of Critical Damage starts at 150%, assuming no other resistances are in effect.

All bonuses to critical damage stack additively. If the attack fails to land a Critical hit, the damage is instead multiplied by a randomly generated value between 0.9 and 1.0, inclusively.

The critical damage multiplier caps at 700%, including buffs and passives. If resistances are in effect, the cap takes in effect after calculations are applied. If the final value exceeds 700%, the overall Critical Damage bonus will reduce down to 700%.

There is also a minor boost to damage equivalent to the unit’s Atk divided by a random number between 25 and 32, inclusively. This increased damage is not affected by elemental or critical multipliers, but is affected by any future multipliers.

Tips
Hard content, including quests from Grand Gaia Chronicles, Summoners’ Research Lab, and Frontier Gate, generally contain enemies that have built-in resistance against critical damage.

Enemy resistance comes in two forms - base damage resistance and buffed damage resistance. These act as multiplicative factors that reduce parameters.
