Status ailments are negative conditions that affects a character or demon during battle. While many are volatile and wear off at the end of battle, some will persist while exploring field areas. Some demons are naturally resistant to status ailments, either to the associated skill type or to ailments in general (Anti-Ailment).
Some skills, such as Eternal Rest, will cause instant death to targets under a specific ailment. Also exact effects may vary slightly between games.
