Haha! Deranged weapons. I wonder if we all would be willing to insert wired-lances (search up weapons from Phantasy Star Online 2) and anything trippy down below in Hell. To give it a proper use (other than a place to spawn upon death; To be killed by your dead 'clones'; And minerals), I would love to recommend what Ozzy just did, but with 'phantasy' armor & weaponry, just in a corrupted hell theme stuck in tricky manners to obtain.
Could go all Skyrim with the weaponry for those that desire those 'soul gems' or whatever from that game down there, or even keeping it regional by only having them effective down there. Wired claw lances would be amusing though, if the combat is going to be revamped to fit this game appropriately now that we have hostile Bears, Mooses, and Goats.
