My friend and I were talking about this today...An ultimate strategy that might be fun to try...
As soon as you get Ramuh equip it and keep it equiped...For the plus 2 Stamina...get the plus 2 stamina for the rest of the game and always have a cure ring or something like that on, eventually the regen will be doing so much it will be like a regualr cure 2, making the person invincible!
