The spiked hammer is a large sledgehammer forged of metal, with a heavy spike on one end. With its sheer weight, it crushes bones and impacts through the hardest of armor as if it were tinfoil. It's similar to the warhammer, but larger and much heavier.
Due to it's heavy form, it provides a +4 to sunder attempts made with the weapon.
