Status Changes
Ailments
Aside from Downed, all ailments last 3 turns by default, shortened by the battle's end or use of certain items or Specials.
Poison
The character will lose 10% of their current HP when their turn comes up. Prevented by the Antidote Pin.
Mute
The character will be disallowed from using the Special command. Prevented by the Wake Up Pin.
Sleep
The character will have each of their turns skipped entirely, other than potential usage of the Switch command on the Switch version, though certain physical attacks by enemies will end the Sleep immediately. Prevented by the Wake Up Pin.
Scarecrow
The character will be disallowed from using the Attack and Item commands. Prevented by the Trueform Pin.
Mushroom
The character will be forced to Defend or Switch on their turn, the former formally displayed as a mere turn skip, but they will also recover 10% of their current HP when their turn comes up. Prevented by the Trueform Pin.
Fear
The character will deal halved damage against enemies (will not stack with Defense Up or the Defend command), and take 1.5 times damage. Prevented by the Fearless Pin outside infliction by King Calamari's Tentacles.
Downed
Lasting indefinitely and harder to undo, Downed is inflicted to a character when their HP is reduced to 0 and prevents them from doing anything at all. If the player wins the battle or successfully escapes, Downed characters will be back up with 1 HP by default.
