Powder

Powder is a recurring enemy ability in the series. It is also a recurring item theme, as it appears in the form of several items, including Dream Powder, Poison Powder, Sleep Powder, Silence Powder, and Zombie Powder. Variants of attacks are usually of the same name as the items, though some, such as Silver Powder and Darkness Powder, never appear as items and are exclusive enemy abilities.
