@Saulot:

Erm... I don't believe so. A good swing with a sledgehammer would, in reality, probably be more than enough to make you kick the bucket, even though you weren't wearing any armour... ><
So a negative damage base doesn't sound like a good idea (put into practice, though, it could represent a good approximation but... Nah, letting a hammer have the same dmg value as a fist doesn't sound too appealing ^^)

@MaxWilson:
True, the hammer has the dmg value of 7 but this is still only one more than the broadsword, whose value is 6... I think such a difference is negligible, especially when taking into consideration all the defence penalities the hammer offers to a unit...
