I am going for the hammer next time,dont see many of them about,i saw this mace called morning star,did 55-97 damage and had 3 charm places avaiable!!
Maybe i was wrong about the above mace stats but i have seen swords do max 105 and axes the same so i expect maces to come within that range.
I think hammers are 90 max,halbaerds 98 max
Of course the better unique mace might just do 120 damage.
