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.

Cold damage is one of the five Damage Types. It is reduced by Cold Resistance. Cold hits apply Chill and build up Freeze, but cannot build up Heavy Stun.

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.

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.
