AG's Boon of Wrestling

You count as a size category larger for the purposes of grappling and shoving, and you have advantage on checks made to grapple or shove. In addition, whenever a creature triggers an Attack of Opportunity from you, you can use your reaction to grapple or shove it instead of making a weapon attack. If you count as a huge creature for the purposes of grappling, you are able to grapple any creature, regardless of its size.
