Ogre Grip

You have trained to master the use of large melle weapons, gaining the following benefits:

• You ignore the Heavy property of melee weapons.
• Provided that your size is Medium or larger; You ignore the Two-Handed property of melee weapons that do not have the Reach property. While doing so you cannot dual wield another Heavy or Two-Handed weapon.
• You always rol the higher damage of Versatile weapons. When wielding a versatile weapon two-handed you deal an additional 1d4 damage of the weapon's damage type.
• You have Advantage on ability or skill checks to avoid being disarmed.

The text in italics: “Provided that your size is Medium or larger”  is intended as an optional adjustment to this feat. The original conception does not include this text. I added the option in case you feel that it is too much for small size creatures to go from not being able to wield a Greatsword, Greataxe or Maul at all to being able to wield them with one hand.
