bone fusion

if you cast this spell you will be able to fuse all of the bones from diseased creatures that you can reach into one being, essentially creating a super skeleton. it doesn't matter if they are bones from goblins, minotaurs, dragons, eldritch horrors, or whatever, they will fuse into one singular being. once the being is formed, it must quickly be given a name by it's creator or else it will go on a violent rampage, killing anything it sees because of all of the creatures various instincts are fighting for control.

the way it looks depends on the imagination of the creator. the basic process is that the creator takes various different species bones, and uses some of one for the arms, a different set for the legs, one for a torso, hands, feet, head, and so on. for example, the torso may be from a large minotaur, the head may be from an arocockra, arms of a grizzly bear, legs of a dire wolf, and maybe some wing bones from a smallish dragon. note, it doesn't have to be in this format. it could be a bone spider of sorts with a terrasce skull as bothe the body and head. or it could be a normal human, but with freakishly large hands from a giant. 

this creature will basically act as a remotely controlled robot for the creator, and will stay in the form it is in until whatever bone is acting like the head is destroyed.
