Etrian 1:FP

FP (Japanese: ＦＰ) is a measure of a character's hunger in  Etrian Mystery Dungeon. When entering a dungeon, all characters will have 100 FP out of 100, and the player-controlled character will lose a FP every few turns, depending on their class. FP is restored by Amber Tiles and items. The maximum FP a character can have can be increased with Glutton Potions or Someii Rice up to a maximum of 200, or decreased with Picky Potions to a minimum of 1. When a character's FP reach 0, they lose 1 HP for every turn they take while they are the leader. They do not lose HP if another character becomes the leader.
