These rare items grant temporary increases to field stats instead of battle attack/defense stats, or else grant temporary Unique field abilities (these do not cancel out a character's existing Unique ability). Because field stats are occasionally relevant to battle, most of these boosts are listed with a turn count, which will determine their duration in battle, but in the field the time that they last will be less specific, and for convenience, if a character uses one of these before attempting to solve a field puzzle, the effect will generally not wear off until the puzzle is solved. The Mini Mushroom listed here is the exact same item as the Mini Mushroom listed in the Beneficial Items section, and it has both its battle and field effects when used.
