I don't think Gristav can afford it by our division methods, or he'd be in line, as his Will save is +2 (pretty faces, and all that). I do agree we might have more need of it than of that cash, unless that Mythic line puts it as a premium.
First off, I don't know what the heck you mean by "division methods" and I don't care. If you want the thing then take it, if not, then someone else will. Simple as that, bud.
Typically, the way I like to play it, is whoever needs it the most. To me that just seems the right way to do it.
Snake's Will is +5 so he'd probably be the last to claim it. But he will if no one else does. :)
And just ignore the Mythic part of it. That's not being used.
