Gorilla Grip

With your great strength, and a decent amount of practice, you have honed the ability to use two handed weapons in your main hand, while still leaving your off hand free to wield a shield or a light one handed weapon.

Upon gaining this feat, you gain the following benefits:

• You gain the ability to wield a two handed weapon in your main hand, leaving your off hand free.
• With your off hand free, you can do things that could normally with a free hand, such as cast spells that require somatic components, interact with most objects, and pickup or carry things that are light enough.
• You can also wield an additional weapon in your off hand if you choose to, however this weapon must have the light property.
• You can still wield weapons without the light property in your off hand, but you have a -5 to hit for those attacks. So you...could wield two greatswords if you really wanted.
• You can use a shield in your off hand if you are proficient with shields.

However, this feat does not let you do certain things, and are described below to clear up things:

• When using a versatile weapon that has an increased damage die when held in two hands in your main hand, it does not increase the damage die until you wield it with both hands, unless you have another feat for that.
• You do not get to ignore the heavy weapon property.
• All crossbows can be fired using this feat, but you do not get to ignore the reloading feature, and must have a hand free to do so with, unless you also have the crossbow expert feat.
• You can use a light crossbow in your offhand, but of course must have a free hand to reload if when needed, unless of course you have the crossbow expert feat.

If this feat needs to be changed or is unfair, just comment down below. I tried to make this feat somewhat realistic, and not just:
"you ignore the two handed and heavy weapon property, the end", as that didn't feel quite right to me.
