Benefit: If you successfully hit an opponent with both
of the weapons you wield, you deal extra damage equal to
1d6 + 1-1/2 times your Strength bonus. This extra damage
is treated as the same type that your off-hand weapon deals
normally for the purpose of overcoming damage reduction
and other effects related to damage type. You can gain this
extra damage once per round against a given opponent.
