Damage Formula

Pre-Mitigation
Skill Damage + Attack Damage
Attack Damage
monster's base physical damage at this level × (1 + passive damage bonus + buff damage bonus)

Multiply the damage before reductions by 100%.

How Damage Is Calculated

  1. Variance: ×0.9–1.1
  2. Backstab: +10% damage when attacking from behind (Rogues with Improved Backstab: +25% instead)
  3. Level difference: ±2% per level (max ±20%)
  4. Slayer reduction (boss or elite attacking a player or pet): −Slayer level × 10%
  5. Enrage: non-spell attacks by monsters below 10% health deal 50–75% more damage.
  6. Damage reduction: −ceil(damage × clamp(target's Defense × 0.0005, 0, 0.9))
  7. Critical hit: ×1.5
  8. Radiant Aether (15% on a critical hit, consumes one item): ×2 again, for ×3 total

Every 100 points of Defense reduce the damage you take from a hit by 5%, up to a 90% reduction before rounding.

Block/Miss Chance

clamp(
  clamp(target's base block chance + target's Defense × 0.0001 + buff bonuses, 0, 0.8)
  + clamp((target level − attacker level) × 0.005, −0.1, 0.1)
  − attacker's Accuracy
, 0, 0.9)

Every 100 Defense adds 1 percentage point to block chance before Accuracy and level difference.

Moving target:
resist chance −25 percentage points, damage +10%
Backstab:
resist chance × 0.8

Aggro

Aggro = min(target health,

  • skill aggro + caster maximum health
  • + damage
  • + round(stunChance × stunTime × 10)
  • + round(fearChance × fearTime × 10)

)
