Mediocre....not worth it IMO

Is it his speed, resistances? Care to elaborate?

it's just works like paladin immortal spirit, when you raised you only get tiny bit left of hp, so if the enemy unit turn after you raise it will be useless

Still, it means enemies need to 🔥 him 3 times to really 🔥 him and waste some turns, lol

Yeah then Rairyuu acts before your unit, nukes two of your units and then you complain on Reddit.
