Okay, um, final question: He uses spells for this, right? Um, as in he casts spells for melding iron, and passive spells for some of the other things. It makes total sense for him to have a limited repertoire of spells(and due to his nature the whole being able to hold iron thing when he's unstable makes sense) given his backstory, I just want to make sure since that's how magic works in-setting.

If he does, um, that's my last question and I don't see anything problematic so yeah.
