Quest for Sky
Its name means “The Mountains Quake in Fear”. This +2 Large adamantine impact warhammer packs a much larger punch than it should be capable of.It can be used to deliver a coup de grace against inanimate objects. This damage bypasses the object’s hardness. In addition, it produces an extra d6 of force damage, bringing its total weapon damage dice to 3d6 +1d6 force damage. If its wielder increases in size, the force damage increases by 1d6.
Conveniently, the weapon allows you to do just that. Once per day, you may cast righteous might (10 round duration, DR 5/evil).
