|“||War hammer +1, +4 vs. giant humanoids: The Knee-capper, or 'The Capper', as it is affectionally known in dwarven circles, is rumored to have been forged by Clangeddin himself. He gave to a small clan of homeless dwarves that they might carve a place for themselves amongst the giants and ogres in their area. The hammer has been passed from hero to hero, occasionally finding its way into non-dwarven hands.||”|
