Dodge

Some effects allow the player to dodge incoming attacks, causing them to be treated as a miss. This produces a hitsplat with the text "Dodged". Only attacks that have a chance to miss can be dodged, and the dodge hitsplat takes priority over the miss hitsplat; if an attack that would have missed is dodged, the dodge hitsplat is shown. Any attack that cannot miss, such as boss special attacks, cannot be dodged even if the damage is not typeless. Anything that relies on the player taking damage does not trigger the effect of it when the dodge successfully rolls. This includes, but is not limited to: Resonance, Divert, Vengeance, Reflect, Disruption Shield, Reprisal, Transfigure, the effect of deathtouch bracelet, and various Weapon Special Attacks that deal reflection damage or stockpile damage.

Sources

Sources of dodge chance include:

Darkness: a 20% dodge chance with a limited duration
Set bonuses of high tier deathwarden robes: Tier 70, 80, and 90 have a 1%, 1.5%, and 2% chance respectively per piece equipped, for a maximum of 5%, 7.5%, and 10% dodge chance

Exceptions

Most auto-attacks from monsters can miss (even if their hit chance currently is 100%). However, bosses that do not check accuracy on their regular attacks are not affected by dodge chance. These bosses include:

The Ambassador
Blood spells cast by Nex during her blood phase (third phase)
- This includes blood spells cast by her minion, Cruor.
Rasial, the First Necromancer
Solak's attacks against his primary target
Arch-Glacor's melee attack in Hard Mode

Some bosses deal half damage of a hit that would otherwise miss. These are unaffected by dodge. Examples include:

Damage inflicted in PvP situations can't be dodged.
