Use Your Head (Sam)

Use this ability twice per day, and no more
than once per hour. Roll GRACE. If you
roll at least a partial success, you headbutt
the target for 1 damage. Then, make an
opposed SWOLE roll. If you win this roll,
take no damage. If you win this roll by 3
or more 3, take no damage AND deal 2
damage. If you lose this roll, take 1
damage. If the target was not expecting this,
they receive a -2 modifier to both rolls.
