I'd limit how you can manipulate metal, or the type of metal you can manipulate, and use the strains for different expansions to those abilities. Maybe the first one lets you move it around your skin (for metal armor) or accelerate it in one direction. Or to add types of metal you can manipulate, like an strain for aluminum or something.Strength of it would be that metal it great defensively and offensively.

Hmm alright, I'll fix it accordingly
