It's not written anywhere so i quite understand garv's confusion about it. Btw, since the things are so, imho, if an enemy is chaosed and gets sleeped it should simply continue to stay chaosed. Doesn't make much sense that by hoarding and damaging more an enemy you actually make him a favor. The same for chaos and immobile. If chaos gets applied over an immobile enemy if the enemy gets healed why should get back the standard action immobile negated? Imho how works now doesn't make much sense but i suppose there's not much we can do about it since are core mechanics.

Yes, that's how it works currently. If you use itachi susano to chaos a target and lets say your sb clone sleeps it and then you use a mystery with tai attribute then in round 2 the enemy is full awake XD (the same applies if you immobile him after you chaosed him).
