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.

Minions are summoned Allies which will accompany and fight alongside you. Persistent Minions will reserve a portion of Spirit while active.

Physical damage is one of the five Damage Types. It is the most common and the only one reduced by Armour, rather than by a Resistance. Most physical damage comes from Weapon Attacks, but some Spells and other skills deal physical damage as well. Physical damage over time can be inflicted with Bleeding.

Lightning damage is one of the five Damage Types. It is reduced by Lightning Resistance. Lightning hits have a chance to Shock based on how much Lightning damage is dealt.

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.
