As of now, it doesn't cost anything to create a Master Account. You can buy points for your MA and use those to upgrade accounts linked to it, though.
@Natesan
I'm pretty sure it does. I got a Warp Guardianship for the discount using it. To check, just go under "My Games", click your WarpForce account name, and look under the Guardianship Options. I just checked, and I'm allowed to upgrade a Character on my verified WF Account for 2000 Points. I believe that's only $10 worth of points, so it should work, just as long as you've verified/linked your WF Account to your other upgraded accounts.
Edit:
@L.O.W.
The Blade of Awe isn't released in AQW yet.
