Design Details

I have changed the base damage so to does less and is harder to hit things without proficiency. Not as overpowering as the original weapons mastery, but the hit points are also not as high, and with magical enhancements I did not want this weapon to become the must have item on the shopping list to enhance to a +3 weapon.
