Will-O-Wisp causes the target to become burned, if it hits. Burned Pokémon lose 1⁄8 of their maximum HP each turn and their Attack is decreased by 50%.
Fire type Pokémon, those with the ability Water Veil or those behind a Substitute cannot be burned.
When a Pokémon is holding Firium Z and uses its Z-Power, Will-O-Wisp turns into Z-Will-O-Wisp and raises Attack one stage, in addition to its usual effect as above.
