Titan Grip

Allows the use of two handed weapons with one hand, while still doing two handed damage. Also uses higher damage on versatile weapons even when used one handed. For example, a Maul could be wield by someone with Titan Grip with one hand and still do 2d6 damage. A longsword wielded by that same character would do the higher of its damage options, 1d10, as opposed to the 1d8 that is normally used when wielded one handed.
