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.

Some Skills, Items, Support Gems and other effects can Break Armour, which lowers a target's Armour by a specified amount. If this brings the target's Armour value to 0, their Armour is Fully Broken for 12 seconds, or 4 seconds for players. On top of not benefitting from Armour, non-player targets with Fully Broken Armour take 20% increased Physical damage from Hits. Players Break 3 times Armour against Normal Monsters and 2 times Armour against Magic Monsters.
