Is there anything (or multiple things) planned that use large amounts of one or two specific resources? I do have to do something with 100+ of something dead. Something luminescent + something dead = blinding powder, maybe?
There might be a use that I just haven't encountered, though, since I didn't get hugely far before dying to a mushroom while attempting to hunt witches. I should've gone back home to make more rust dust to carry on through an abandoned fortress.
It might also be interesting to see potions applied in different ways, like as traps.
