Any damage that isn't damage over time is Hit damage. Damaging Ailments which result from a Hit will calculate their damage from that Hit, and will not subsequently have Damage modifiers applied directly to them. As a result of this, raising Hit Damage will result in more powerful Damaging Ailments innately.

Chaos damage is one of the five Damage Types. It is reduced by Chaos Resistance. Chaos damage is the least common damage type, and removes twice as much Energy Shield as the damage value when taken.

By default, specific Ailments are calculated based on only specific damage types, such as only the Fire damage of a Hit mattering when inflicting Ignite. Allowing another damage type to contribute to an Ailment means that all damage of the relevant types is summed when performing calculations for that Ailment. For Ailments that use Hit damage to determine Ailment chance or buildup, this means that the damage type becomes capable of inflicting that Ailment. For Ailments that only use Hit damage to determine Ailment Magnitude (i.e. Bleeding and Poison), you still need a way to apply those Ailments (e.g. a source of Bleeding or Poison chance).

Freeze is an Ailment that causes targets to be unable to move or act, and lasts 4 seconds by default. Cold damage from Hits Contributes to Freeze Buildup on enemies until they become Frozen.
