they seem to both hit the same.
is it cuz of spec?

It has a 102 crush bonus and 85 str bonus and ss has like a 82ish? slash bonus, and a 82 str bonus. Most people using the bludgeon really notice the difference when training on monsters weak to crush because the bonus is so high. At sand crabs it is easily a 15-20% improvement on your xp per hour.

thanks very much
