So with 'demons' being an upcoming enemy, and demon bone armor being a thing, it seems very counter-intuitive since Evil characters cant (or shouldnt?) kill Demons, but the armor itself sounds like it would be entirely evil. Should evil players barter with Good players for the material ? So what shall Good players want in return? Maybe angels drop feathers used for robes or other items ? 

 

It'd actually be kind of interesting to rely on trading with the enemy.
