Sumo (fighting style)

Sumo is a fighting style. While you have this style, you gain these benefits:
     Your talents for close-quarters grappling have been developed to legendary heights. You gain the following benefits:

• You can grapple a creature of Huge size or smaller, regardless of your own size. If the creature is more than one size category larger than you, your speed is reduced to 10 feet while you are grappling it.
• You have advantage on attack rolls against a creature you are grappling.
• You can use your action to try to pin a creature grappled by you. To do so, make another grapple check. If you succeed, you and the creature are both restrained until the grapple ends.
