Mechanics
In Kingdom Hearts χ, Special Attack Bonus is an item that adds a damage multiplier to Player's abilities when collected. Special Attack Bonus can be collected with the Power Bangle after reaching level 20 by defeating specific Heartless called Guilt Targets (ギルトターゲット). It comes in five different sizes, and differnet Guilt Targets drop different Special Attack Bonus prizes. Once Special Attack Bonus is collected, it will add bonus damage to all attacks, which is four times more effective against Raid Bosses (this special bonus damage does not apply to Chain Bonuses during Raid Bosses). After a certain period of time, the collected Special Attack Bonus and damage multiplier is reset, and the Guilt Target is updated.

In Kingdom Hearts Union χ, Special Attack Bonus is an attribute found on 6★ Medals which have been strengthened with the Power Bangle more than five times. Special Attack Bonus provides an additional damage increase on top of any multipliers given by strengthening the Medal. There are 10 levels of Special Attack Bonus, determined by a Medal's rarity, each with a set range of possible damage multipliers. When a Special Attack Bonus is first applied, a value in that range is randomly chosen; this value can be re-rolled by strengthening the Medal with or an additional copy of the same 6★ Medal, with the higher value being kept. By strengthening a Medal with Medals, the Special Attack Bonus increases by 1%.
