After going down a wormhole on Wikipedia, where I went from the war in Afghanistan to headhunting (taking the heads of enemies as trophies) I got an Idea. Craftible skulls! Most evil factions already have skulls decorating their buildings, but outside of the Lands of the East and South, finding these structures can be a headache. The skulls will be crafted by putting 7 bones in a I shape on a normal crafting table, because this way everyone can get in on the skull fun! (who would not want to make pyramids of skulls outside their bases?) Making the skulls craftible instead of making them droppable will help prevent involuntary clogging, and also give us to that stack of bone besides farming. there could also be different skulls for different races, like Ork, Elf and Troll skulls.
