The woodcutters tool, adapted for combat. Not a very agile weapon, but it does insane amounts of damage.
Great Blow
A Great Blow is a powerful all-out attack. It always requires two hands, even with a weapon that is normally used one-handed. It receives a +3 bonus to your damage, but you cannot do anything, such as an ActiveDefense, until your next shot comes up.
Great Blow does not combine with Bash.
