• Common Magic, when not Concentrated, can consist of Talents, Charms, Feats, and Spells and these abilities can only be used as passive augments to other abilities.
  • A Charm is something you have.
  • A Feat is something you are.
  • A Spell is someting you do.
  • A Talent is something that is part of you.

• Concentrated Common Magic restricts the user only to using Common Magic Talents (exception: Self Rock Teaching in the main book), but the abilities learned can be used actively, instead of only as passive augments.
  Example: I concentrate my Common Magic. Now, instead of rolling my Jump skill to get over a Gap, I can roll my Jump Over Gap talent, and the resistance the GM is rolling against me is 14, NO MATTER HOW BIG THE GAP IS. (This is because "The World" resists magic specifically designed to overcome it with a default ability of 14.)
  But it's still complete crap for jumping over a fence.
• Doyce, Mike here. There's yet another form of concentration that I'm not sure if you want to include or not. It's diety specific concentration. In this case, you can have any and all sorts of common magic, or even specialized magic, as long as it's all from one diety. The usual example is concentrating in Donandar or Lanbril, but the implication is that it can be done with specialized magic beings, too. If some of them have a "common" aspect, then that magic is allowed as well. I'm not sure there's a Gloranthan example that I can come up with (and so maybe it's supposed to be impossible), but in the SW game, I have Andaras available as both a common magic religion, and in other places as a full theist cult. I think that the CM religion gives charms. So, concentrating in the diety Andaras, instead of in the "Mundane World Magic" that gives you only talents, you can keep any CM magic charms, and any theist affinities you might hav. Anyhow, that's how I intend to play it. There's something on this in ILH, and I just read a section on it in MOLAD.
