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.

Spirit is a reserve of power used to activate and maintain skills with permanent effects. Spirit-powered skills are managed within the Skills Panel. Weapon Sets can have differing amounts of available Spirit, due to weapons with Spirit (such as Sceptres), Weapon Set Passive Skills, or Persistent Skills that are active in specific Weapon Sets.

Reservation effects prevent a portion of a given resource — usually Spirit, though it can also be Life or Mana — from being used for other purposes while active. Reserving a resource does not change the maximum value of that resource.

The Magnitudes of a Buff or Debuff are the values of the stats it applies to the target. A Buff or Debuff with higher magnitudes is more powerful. Modifiers to the Magnitude of Buffs or Debuffs come from whoever applies it and are multiplicative with modifiers to the Effect the Buff or Debuff has on the target.

Your allies include other players, Minions, and any other entity that fights alongside you and has its own stats. You do not count as your own Ally.
