I know there is a global constant for the time alotted to Beastmode, but is it possible to mess with your Claw damage

As according to the Perk/Scripting, the Unarmed AV is what is used in the Claw Calculation

EX:
(Transform)
Player.Forceav UnarmedDamage 200 (Usin' Force Av so it sticks and wont revert)

EDIT: Yes, its gonna unbalance your default punch...
