Buffs

Most often, a buff refers to a temporary beneficial spell or effect placed on a player. Buffs can range in effect from simple personal shields to buffs which augment almost every category of stats a given player may have for their race or class.

Buffs can be of two types: those that expire over time and those that are dependent of the environment around you.

You can dismiss an active buff that expires over time by right-clicking on its icon.

Most buffs do not stack with other similar buffs. One prominent exception is heal over time spells, heal over time spells from multiple characters and different heal over time spells from the same character will stack with eachother.

Buff can also be used as a verb, i.e. "to buff" means to apply buffs.

Buff is also used to represent a change to a class or ability that makes it more effective or useful. It is the opposite of a nerf.
