Well, he's been shown managing incredible weapons and he's still young, so he can hone these new skills he combines with his past life knowledge.

I was a bit surprised he knows his Mendeleiev table so well, down to several decimals.
He also has a good understanding of matter and metals atomic structures.
I guess he's at least College graduate or even higher. For a tool, he had quite the education and gift for learning.
I would not be surprised he had quantum physics courses. That would go well with magic.
Antimater would then be trivial:
-coordinates 250km south, 320 km east.
-generate antimater

booooom haha
