What's the single most useful ability, weapon, armour and relic in your opinion? Almost every ability and weapon etc has it's uses but which do you find the most useful?
I'm talking in terms of the entire game so before saying chicken knife or braveblade, remember you don't find them till the very end... not very useful for the first half of the game. And for abilities i mean a single ability so don't just say summon or white, say which level summon or which level white.
Should be interesting to see what people think on this
