Probably the worst answer, but i just love how osrs wastes my time, and the sense of achievment i feel when i finally get that item that i wanted for so long
In OSRS they are used to "reanimate" undead versions of the enemy. Since the Arceuus book isnt implomented yet. And im sure Omicron (sorry for miss-spell god) has better stuff to do, that they will stay quite useless for a while.
Good idea tho if it doesnt take too long to develop!
