In OD&D and Holmes, one of the stated advantages of being a dwarf is that they are the only ones who can wield the +3 Magic War Hammer.
My take has always been: uh, ok... that's nice... I suppose... but pretty damn specific! :)
But it recently occurred to me that this could be a prime role playing opportunity for a high level dwarf - getting that damn +3 Magic War Hammer!
Has anyone ever given one out in a game of OD&D or Holmes and weaved it into the campaign as a nice opportunity for a quest or even a dwarven obsession?
