View source for Buff

'''Buffs''' are a type of [[Active and temporary effects|effect]] that can modify a creature's statistics and can be identified by having a specific green border around the icon.<ref name="IdentifyBuffs" /> Those with primarily detrimental effects are typically referred to as ''debuffs'' and have a red border.<ref name="FlaskBuff" />

==Identifying a buff==
[[File:Onslaught buff icon.png|thumb|upright|[[Onslaught]] Buff icon with green border]]
Each buff affecting the player will display an icon with green border in the top-left of the screen.<ref name="IdentifyBuffs" /><ref name="FlaskBuff" /> 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. For other icons shown there see [[active and temporary effects]].

==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 {{il|Wrath}} aura, the monster is not "hit" by the aura, or the buff, it is the player that hits the monster:
#Wrath is a [[spell]] that is cast by the player.
#The spell creates an [[aura]] that applies a buff to any allies within range.
#The buff contains a [[modifier]] that adds lightning damage to the player's attacks
#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 [[aura]]s). This duration is affected by {{c|mod|Buff Duration}} modifiers, and can also be affected by {{c|mod|Skill Effect Duration}} modifiers if the buff was applied by a skill.

The passive skills which increase buff and debuff duration apply not to buffs on you but to buffs (including debuffs) you create, either on yourself or other entities. This includes all the above as well as such things as the debuffs placed on cursed monsters.

'''Buff expiration''' - Being cursed with [[Temporal Chains]] and having the [[Shaper's Presence]] buff can make {{c|mod|Other effects on Cursed enemies expire % slower}}. These 2 mods are additive with one another and capped at 75%.
*'''Example''' At 50% {{c|mod|Other effects on Cursed enemies expire % slower}} all buffs expire 2 times slower. This is equivalent too 100% more buff duration for calculating total buff duration.

==Buff effect==
The effect of a buff can also be increased or reduced. Modifiers that increases Buff Effect increase the bonuses from buffs that affect yourself, that includes both positive and negative bonuses. Therefore one has to be careful when amplifying two-sided buffs. 

Currently, the only source of {{c|mod| #% increased Effect of Buffs on you}} comes from {{il|Ichimonji}}. This will for example increase:
*The amount of [[mana regeneration]] granted by the {{il|Clarity}} aura.
*The amount of {{c|mod|Fire Damage per second}} taken by the player using {{il|Righteous Fire}}. It does not increase the amount of {{c|mod|Fire Damage per second}} dealt to enemies since the mod specifies "on you".
*The spell damage bonus provided by a player using {{il|Righteous Fire}}.
*{{il|Blood Rage}} increases the life leech amount as well as the attack speed on you, but also increases the total amount of Life and Energy Shields lost.

{{anchor|Debuff}}

===Buff copies===
* Multiple copies of the same buff do no stack with each other. When multiples copies of the same buff are on one character, the game will only count the strongest buff as active.

==Debuffs==
[[Image:screenshot-0140.png|thumb|upright|[[Bleed]] Debuff icon with red border]]
A debuff is a type of [[Active and temporary effects|effect]] that '''only''' provides a detrimental effect to the debuffed creature and can be identified by having a specific red border around the icon. For instance the damage over time from [[Bleed]] or [[Poison]] are considered debuffs.<ref name="PunctureDebuff" />

=== Exception ===
Standing on enemy's [[consecrated ground]] is displayed without red border and is displayed as normal skill effect. Only such case.

==Interactions==
===Monsters that can remove Buffs===
*[[Nemesis]] [[monster]]s can have a modifier called nullifier. This will remove all temporary buff effects on a character every time the monster [[hit]]s a character.

==Related Effects==
The unique jewel {{il|Mantra of Flames}} has the unique mods {{c|mod|Adds (3-5) to (8-12) Fire Attack Damage per Buff on You}} and {{c|mod|Adds (2-3) to (5-8) Fire Spell Damage per Buff on You}}.
