Centrifugal Swing

Description
Weapons that are unbalanced and heavily weighted towards the top take a lot of time and practice to master, but you've grasped the basics well enough to know how to use that poor balance to your advantage. While it takes more time and a good deal of effort, you can make a wide arcing swing like a golfer to add a lot more punch to your attacks.

This also works with weapons that are balanced, but long and heavy; like staves and spears.

Effects
When you use Centrifugal Swing, you spend 6 Stamina and 3 AP. You make a single attack against an enemy you can reach with your melee weapon. This attack carries a 1 die penalty to hit, but the damage bonus you get from your PHY score is doubled, as though you were wielding a Heavy weapon. If you are already wielding a Heavy weapon, you deal an additional 1d6 damage instead.
