I'm happy to do another mission!

First my character needs some downtime though. I think I need to learn how to use my battle skills more effectively first.

I had Hayato suggest attacking from range in-character, but some magic using characters who use what might be called the Metal element I can think of are Archer and Shirou Emiya from Fate/Stay Night, Musica from Rave Master, and some of the alchemists from Full Metal Alchemist. There's also a fantasy series called Mistborn that has all their different types of magic revolve around the properties of different metals. You'd probably want to look out for spoilers if you ever plan on reading/playing/watching any of those, but I'm sure browsing their wikis or something might give you some ideas.
