Why so many flames?

They could work as a consumable. I don't see them working as a KI. In fact there already is a KI that gives a raise effect. It's called Atma of the Apocalypse.

However yes I agree, Phoenix Downs could work, and I would more then likely carry a stack on me.

I don't carry a hairpin on me because when I am in some form of risk of dying I carry a WHM along with me. However I do carry a RR scroll which obviously only has one use - then you are stuck on the field without RR for a 2nd time.

Why not make a raising item?
