Monkey Grip

Gripping a weapon is something anybody can do, but through rigorous training and  pure strength, your grip is stronger than the average.

When taking this feat you gain the following benefits:

• You may wield a two-handed weapon in one hand, however you must be holding it in two hands to benefit from great weapon master and the great weapon fighting style.
• Before you make an attack with a weapon that you are proficient with in one hand, you can choose to take penalty of up to 1-5 from the attack roll. If the attack hits, you can add the amount you took as penalty to the attack’s damage.
