I will soon have to try my hand at the DoL/DoH classes (most of my battle classes are approaching 50), and I'd like to clean out my inventory but I'm just not sure what I'll need for, say, Coil, when/if I decide to do it.

I have basically hoarded everything I've ever gotten from quests, including a few varieties of ward potions, lots of different stat boost potions, healing potions and ethers, elixirs, etc. So what of all of this is absolutely needed?

On top of this, I have several varieties of food items that I think I can sort through on my own.

Also, one of my retainers is holding all the drops I've gotten over the months that are presumably "crafting materials".
