Well, I said that creating humanoid creatures is a very complex task, and in this case, I performed two checks: the first for channeling and the second for giving the desired form. If the first check had failed, the spell would simply not have worked. If the second check had passed, I would have gotten a "hollow" Waon. As it is, the spell went out of control, as if a critical failure had occurred.
Black magic is no joke.
