Overwhelming Cleave

Juggernaut Approach: 10th level When you successfully push a creature into a surface or another creature while raging, the pushed creature takes kinetic damage equal to your Rage Damage. Additionally, the first time you hit with a melee weapon attack using Strength each turn, you can attempt to damage another creature with the same attack. Choose another creature within 5 feet of the original target and within your reach. If the original attack roll would hit the second creature, it takes damage equal to your Strength modifier. The damage is of the same type dealt by the original attack.

Granted by Juggernaut Approach at 10th level.
