Prerequisites: 5th-level, Strength of 13
In place of an attack, you can strike the ground and expend Exploit Dice (up to your Proficiency Bonus), turning the area within 5 feet of you into difficult terrain.
Creatures in that area must make a Strength saving throw. On a failure, creatures take bludgeoning damage equal to the Exploit Dice spent + your Strength modifier and fall Prone. On a success, they take half damage and do not fall Prone.
