CLAW AT THE MOON

The Jump checks DC is equal to your targets
AC. If this check succeeds, your attack deals an
extra 2d6 points of damage. If this attack
threatens a critical hit, you gain a +4 bonus on
your roll to confirm the critical hit.
If your check fails, you can still attack, but you do
not deal extra damage or gain a bonus on a roll to confirm a critical hit. The maneuver is still considered expended.
