As of yesterday, you can craft with materials from the vault and ten cooking items have been added to world drops instead of karma merchants. When the former is complete (discovery still requires items in inventory, and cooking is all about discovery), that will be awesome and the logical next step from having that huge crafting vault, although the present dis-economies of crafting are broadly known.
The latter we stumbled upon because sticks of butter have been added to the tier 1 drop bags. Some enemies, you see, will sometimes drop a bag o’ stuff as loot. You build up a bunch of these while fighting bandits or centaurs, then double click them to see what is inside. They usually have crafting items and/or a bit of coin. Last night, we found that a great many ettins had four to seven sticks of butter in their pockets. Naturally, we wiped off the lint and put butter in the vault, where it belongs, next to the vials of blood.
It is very nice to get the occasional bit of cinnamon while taking wood from trees. The drop rates on the cooking materials feels a bit high, as I would not want these to displace the rarer, more needed blue crafting drops (like all that blood I am taking from enemies with my field medical kit). Still, anything that gives ettins better access to butter is an improvement in civil society.
