Unyielding (Combat perk)

On the field of battle, you stand tall as a mountain—majestic from afar, unforgiving up close, and indomitable as the roots of the earth.

When you use none of your movement during your turn, you settle into a steady defensive stance. Until the start of your next turn, you have Advantage on any ability check or saving throw made to resist being knocked Prone or forcibly moved.

The effecmt ends early if you willingly move from your space.
