If a PC had a spirit binding enchantment on an object, had a command spirit spell and was able to defeat the Black Growler's Spirit in spirit combat, could they then force said spirit into the enchantment at the time of the Black Growler death? If then the Black Growler's body (assuming it didn't dissipate?) was skinned and tanned could the spirit be bound into the skin and the PC wear it around like a cloak and hood? If nothing else it would be interesting for that character, even better if it were a Basmoli? Several big if's there of course but curious on the feasibility of it. Also the spirit would be hostile of course but possibly any cooperation would geas the wearer to drink blood, kill live animals, eat their organs with the Growler's claws? Etc. etc. Maybe the have to struggle each season to not be consumed by the Growler's spirit and transformed bac into the beast physically?
Any ideas how this could be done if the skin/body didn't dissipate and the spirit could be bound at its death?
