Buffs are temporary positive effects in Xenoblade Chronicles X. They are a type of Battle Effect, and the opposite of debuffs. Buffs can be granted by arts, weather, and Battle Probes. Augments can be considered to provide Buffs which last for as long as the augment is equipped.
Buff Arts, represented by the green color, provide a wide variety of buffs in battle. When granted from Buff Arts in battle, the level of the buff and its duration are based on the level of the art being called. For example, a level 4 art will grant a stronger and longer buff than its level 1 counterpart.
