looks: handel is made of very rare gray stone, the head is made of the same stone, the head has small spikes at each side.
effect: deffence -5% whit each hit.
history: one day a veteran warrior decided to make a hammer for his newborn son, so he could 1 day use it to battle monsters, and eventually the dragon that destroyed his village. the spikes are designed to weaken the armor or scales of anything it hits.
sorry about the bad history thing, im not really good at such things, but i'd like to give it a try :p
