I feel like Mira's revive ability is a bit useless if I could just use stimulant. So I have an idea to make it special: Apart from reviving the dead it can also be used on living members to give them "auto revive" status for 5 turns.

As the name goes, upon their death they'll be revived immediately and the status will be consumed. The status can be renewed but it can neither be stacked nor be extended beyond 5 turns.

I'm not sure if its easy to code, but it could be a useful insurance if you're not sure someone could wait for Mira's turn to be healed. Or you could have them focusing on attack without wasting a turn using potion. This could also opened up a possibility of a new  "revive all" ability without worrying about wasting it on living member.
