Buff

A Buff is a type of effect that is attached to a creature, which can modify that creature's statistics.

Identifying a buff

Each buff affecting the player will display an icon in the top-left of the screen. This is one way to determine whether or not an effect is a buff - if it does not show an icon, it is not a buff that is attached to the player. The exception to this is charges and elemental status effects, which also show an icon but are not buffs.

The functioning of buffs

A buff simply adds statistics and modifiers to the creature it is attached to. Although a buff may increase the damage of the that the affected creature deals with hits, a buff itself cannot deliver hits or take any action. A buff may include degeneration or damage-over-time effects. For example, if a monster is attacked by a player using the Wrath aura, the monster is not "hit" by the aura, or the buff, it is the player that hits the monster:

1. Wrath is a spell that is cast by the player.
2. The spell creates an aura that applies a buff to any allies within range.
3. The buff contains a modifier that adds lightning damage to the player's attacks
4. The player hits the monster, dealing the added lightning damage

Buff duration

All buffs have a duration, which can be infinite (as in the case of auras). This duration is affected by modifiers, and can also be affected by modifiers if the buff was applied by a skill. For example, the buff from a Quicksilver Flask that provides will be affected by modifiers, but not by modifiers, since the buff cam from a flask, not a skill.

Buff effect

The effect of a buff can also be altered, buff effect modifiers alter the numerical values of the buff. For instance, the notable passive skill Inner Force grants an 18% modifier. This will increase:

• The amount of mana regeneration granted by the aura
• The amount of armour provided by a Granite Flask
• The amount of taken by the player using
• The spell damage bonus provided by a player using
• etc.

It will not increase the the amount of taken by monsters that are nearby a player using , because Inner Force specifies it only applies to buffs "on you".

Debuffs

A debuff is simply a buff that only provides a detrimental effect to the debuffed creature. Effects must be closely examined to determine whether they are considered a buff or debuff by the game, as it is not obvious. For instance both the bonus spell damage and the self-burn damage from Righteous Fire are part of a single buff, despite the fact that the burn is a detrimental effect.
