Meat Tornado

You've learned to put the weight of a weapon to your advantage, letting you swing it around you like a mad man, hitting everything around you. When using a Heavy melee weapon, you gain the following benefits:

• On your turn, when you take the attack action, you can instead choose to swing your weapon wildly around you. Roll to attack each creature within 5 feet of you, friend or foe, with a -5 penalty to the attack rolls. On a hit, you do your normal weapon damage.
• Each creature that is hit by your attack is pushed back 5 feet away from you. If the target is a Medium or smaller creature, it must succeed on a Dexterity save against a Strength (Athletics) roll made by you or be knocked prone.
