I Will Ask You Questions - Now with MORE fantasy ecology!

I've been instructed to get in on this. Pretty please?

If there were an elemental magic system which, instead of the classical elements (air, wind, fire, earth), relied upon manipulation of periodic elements, what would these wizards' powers look like?

I really like the idea that most people in this system have these powers as apply to extremely rare or synthetic-only elements. The more common the element, the rarer the power, so there are actually only a few Mg-mancers or O-mancers (and not too many more of the obvious badasses like Fe-mancers or Hg-mancers).

I'm also assuming that all these wizards only have powers over one element in its elemental form, which means for anything more molecularly complex than that, you need a couple people to cooperate. So, to bend steel, you'd need a Fe-mancer and a C-mancer. Finding a suitable partnership to move water is pretty much a pain in the ass. I'm a Ta-mancer.

Sorry I just remembered this thing was here
