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.

Minions cannot normally deal critical hits, only by wearing a full set of Monk armor or Shinobi Infiltrator armor with any of the Lightning Aura sentry summons or by using a Morning Star or Kaleidoscope with any minion can crits be dealt at a fixed rate depending on which is used. The armor set bonuses and whip effects can be stacked for a maximum of 35% crit chance.

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

Notes

• Damage is doubled after being reduced by defense.
• When held, weapon modifiers affect all outgoing critical hits from that class's projectiles. Weapon modifiers will cease affecting critical chance when not selected.
• While ammo might seem 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.
