Okay, so I have several actions I need to take, the first of which is to Levitate the big galoot off of his spear, then stabilize and diagnose him, then first aid him, then heal him. I am pretty sure at some point in there, probably during the Heal spell, that the spear needs to come out, but until then what little I know about wound trauma is that it needs to be left alone. The problem will be getting him out of here, so I think Devon will Levitate him up and turn him over, and stabilize him here, then try to get him out of here if he thinks he has enough time to get him back to the clinic before the 'magic hour' is over.
Devon would know the right way to do things so if my inexpert process is wrong I will edit.
