Stand Against the Tide

General Feat (Prerequisite: Level 4+, Strength 13+)

You gain the following benefits.

Improved Cleave. When you hit a creature with a weapon with the Heavy, Versatile, or Reach property as part of the Attack Action on your turn, and that creature is reduced to 0 hit points from that attack, you can apply that attack roll against the Armor Class of a number of creatures within the reach of your weapon equal to your Proficiency Bonus. Any creature hit by these additional attacks takes damage equal to your Strength modifier. If you have Weapon Mastery in a weapon with the Cleave property and you use that weapon for this feature, you deal damage to each creature beyond the first equal to twice your Strength modifier.

Clearing Sweep.  Once on your turn when you take the Attack Action, you can replace one of your attacks to swing your weapon in an arc at every creature within reach of your weapon, forcing the creature to make a Dexterity saving throw at a DC equal to 10 + your Strength modifier.  On a success, the creature moves 5 feet away from you into an unoccupied space.  On a failure, the creature is knocked Prone.  If the creature succeeds but no unoccupied space exists within 5 feet, it is knocked Prone instead.
