Heroes/Leader

[McNibs]

Me and roommate play pretty relaxed game ie point limit but pick whatever units. So at the moment we are at 1590 and I have 3 leaders skragott, troggboss, and Mollog.i am wondering about artifacts and command abilities. My allegiance ability of the trogg party gives me the command ability to give my trolls magic resistance.

Who gains that command ability?

Who has an artifact / can receive one?

You have to pick your General, if it's not a unique character (in this case only the Troggboss) you can give that General a Command Trait.

You can also grant an artefact to one of your heroes, doesn't have to be the General, though again only to non uniques. 

Some allegiances or sub allegiances may specify a certain Trait or Artefact that must be given, else you are free to pick from those available.

On a more specific note Glogg's MegaMob gives the command ability Oblivious to Sorcery can both Troggboss and Mollog use this ability to give two different units resistance?

No because as per the Core Rules, each Command Ability can only be used once per phase.
