I am a little confused by the coffer in you battle tower bedroom. It seems like some items can be in the coffer and still be used while others cannot. I think you can leave formulas in there and enchantments and you enchanter and aclchemist still use them but not charms or necromancer limbs and I have not tried storing alchemical ingrediants in there yet and wonder if you have to have them for the alchemist to make potions. Can anyone verify for me how the coffer works? QAlso what is the difference between the gems and minerals. There are two runners for the two kinds of items but aren't they both for enchanting?
