Prerequisite: Great Weapon Combat Style, Cleave
You can strike many adjacent enemies with a single blow. Once per round, when you hit on a melee attack with a heavy weapon with which you are proficient, you deal damage normally and can make an additional attack against a foe that is adjacent to the previous foe and also within reach. If you hit, you can continue to make attacks against foes adjacent to the previous foe, so long as they are within your reach, until you either miss or run out of targets. You cannot target a creature more than once during this attack. When you use this technique, attack rolls against you have advantage until your next turn.
