The Legend of Zelda: A Link to the Past/Items

Selectable items
These items can be used one at a time. Some of them consume magic points (MP) when used.

By using Magic Powder on a shrine next to the blacksmith's house, a strange bat-like creature appears and "curses" Link, resulting in a doubled Magic Meter. The one-half means that magic is drained at one-half the normal rate.

Continuous items
These items are active at the same time. By pressing the A button (SNES), the appropriate item will activate, depending on the context.
