Buffs

Buffs and debuffs are changes to an individual's capabilities. They include activated prayers and changes in levels of combat skills. A positive change is called a buff, while the negative counterpart is called a debuff.

Buffs are changes to a character that enhance a player, whether it be by raising skill level or helping the player in some other way. Buffs can generally be classified as either temporary, indefinite, or permanent.

Temporary buffs must be activated or initiated, and will deplete or end after a set amount of time.

Indefinite buffs are buffs that retain when certain conditions are met; they do not exist in all situations, such as when an item is unequipped. Passive effects can be considered indefinite buffs.

Several buffs are truly permanent, and are unlocked after completing quests, diaries, or certain skilling tasks. They do not require any additional items to be on the player to activate.

For permanent unlocks, such as Saniboch's 1,000,000 fee for permanent access to the Brimhaven Dungeon, see unlockable passages.

Debuffs are changes to a character that weakens a player, whether it be by lowering a skill or inhibiting the player in some other way. The following are classed as debuffs:

Many items have dual buffs and debuffs. For example, spicy stew can boost some stats while draining others.
