Chaos damage

Chaos damage is one of the five damage types. It is the rarest damage type and the hardest to get resistance against. Chaos damage bypasses energy shield, reducing life or mana directly. Although chaos damage reduction is based on resistance value, it is not considered elemental damage. One can become immune to chaos damage with the Chaos Inoculation keystone passive.

Poison is a debuff that deals chaos damage over time.
