Augments are items which can be placed into Augment sockets, usually on Equipment items. Once socketed, they can be replaced by other Augments, but cannot be removed by normal means. The types of Equipment which an Augment can be placed into and the corresponding benefit provided are listed on the item.

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.

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.

The three Elemental damage types are Fire, Cold, and Lightning.

Resistances reduce damage taken of the corresponding damage type — Fire, Cold, Lightning or Chaos — up to a Maximum. Fire, Cold and Lightning Resistances are Elemental Resistances. Resistances can be improved with Equipment, Passives & Quest items. Your Elemental Resistances are lowered as you progress through the game. Elemental Resistances are a vital defensive tool, and should be one of the first things to check if you're having difficulty surviving.

Weapon, Armour, Belt, and Jewellery Items are Equipped to the character in the Inventory Panel. Flasks, Skill Gems, and Jewels are never considered to be Equipped.
