Critical hit

A critical hit.

Critical hits occur randomly when striking enemies. By default, each successful hit on an enemy has a 4% chance of being a "critical hit", dealing approximately double the usual damage of the weapon in use with 40% more knockback. A small number of weapons have a base critical strike chance that is higher than the 4% default. In addition, certain modifiers, armor bonuses, accessories, and buffs can boost the player's effective critical strike chance.

Visually, critical hits are displayed as slightly exaggerated bold damage numbers that linger on-screen for a longer period and travel slightly higher than damage numbers from ordinary hits.

Note that minions cannot currently deal critical hits. The only exceptions are Lightning Aura sentry minions used while wearing a full set of Monk armor or Shinobi Infiltrator armor, which will deal critical hits based on a fixed 16.7% (for Monk armor) or 25% (for Shinobi armor) chance.

Players attacking other players in PvP will also not deal critical hits.

Notes

• Damage is doubled after being reduced by defense.
• While ammo is seemed to be affected by crit bonuses, crit chance actually entirely depends on weapon stats.
• It is generally best to attempt to equalize your total accessory crit chance bonus and your total accessory damage bonus, as this will maximize your overall DPS.
