Improved Grappler (Strength)

You're a competent close-quarters fighter, using your grip on an enemy to drag, slam and even throw your enemies. 

• You have advantage on athletics checks to grapple enemies, along with attacks against enemies you are grappling.
• In the place of your own movement, you can move a grappled target to any unoccupied space within your reach, and each 10ft the grappled target moves only counts as 5ft of your movement speed. If you move the enemy in a way that would cause them to collide with an object or creature, the target (and creature, if applicable) takes 1d8 bludgeoning damage. This damage can only be taken once per turn.
• If you take the attack action to shove an grappled target away from you, you gain advantage on the resulting athletics check and the range you shove extends depending on your size in relation to the target. Shoving an equally-sized target pushes them 15ft in the direction you choose (except upward). For every size bracket above the target you are, increase the distance shoved by 5ft, up to a maximum of 30ft. Shoving targets in any size larger than you pushes them only 10ft. If the enemy falls 10ft or more in the course of their forced movement, they fall prone. Regardless of the distance the enemy is pushed, the grapple is broken.
• When you shove a grappled target prone, you can take a free action to switch from grappling with one hand to another limb (for example, a foot), allowing you to use two-handed weapons while grappling the target. Additionally, you can take an additional attack as a bonus action on the turn you shove a grappled target prone.
