Sephiria / Sephiria damage calculator: defense, penetration and critical hits

Damage calculator

Compare critical bonuses and defense penetration for a single hit. Enter the damage before critical hits and defense. Results are before shields, dodge and conditional effects.

How the bonuses interact

Positive defense reduces damage by 44.5% × ln(1 + defense ÷ 40), capped at 100%. Defense penetration reduces that reduction by its percentage; it does not subtract points from defense. Negative defense increases damage.

Critical bonus damage is added to the normal hit. A 100% bonus produces twice the hit damage. Execution adds twice the critical bonus when its excess-chance roll succeeds. Critical resistance first reduces the attack's critical chance.

True damage is added after defense. Toughness is then subtracted, with a minimum result of 1 damage.
