Raise

[CloudedSquall]

There is a technique called Revive that can be bought later in the game.

Revive: Use all caster's HP to revive a KO'd ally with full health

The bottom line is you still have to spend a Phoenix Down or Raise on the caster but you get an ally with full HP. I use that a lot with Penelo (my weakest) to revive Basch (my tank).

Ahh, I apologise. I mean Revive! Where can i find this?
