[@Dead Cruiser]: I'm not so sure about this. You don't really go into his abilities very much, so with the vague nod to his sealing spells, he's either overpowered or underpowered, it's hard to tell. Blank Canvas edges into an area I don't really like in RPs(perfect ability copying) as well as making him kind of ineffective if it's his primary combat ability given its limitations.

[@Savo]: "Programming" a homunculus is one of the reasons to even make them, along with the ability to determine physical capabilities. It's essentially custom-making a human, with all the skills and physical traits you want. You can make them, from the moment they're alive, instinctively know how to do things with the same level of skill as someone who has trained their whole life. You can make killing come to someone as naturally as breathing. Messing up during creation of a homunculus can have some pretty horrible results, though.

Also the transfer would have to have happened very, very quickly, since the soul lingers around the corpse for faaaaar longer than the consciousness part does.
