Edward gets worse in the Japanese version: a skill they omitted for the American release was something, I think it was called "Medicine" - what it'd do was, it'd take a Cure1 from your inventory and split it across your party. By the time you get him, Cure1s are already borderline too weak to be useful, so imagine that but divided by 5. Everyone recovers something like 10 HP. And to add insult to injury, it's glitched: if you have multiple stacks of Cure1s, his skill decrements each stack by 1, but it still acts like he only used one. It might just be the worst skill across JRPGs overall.
