Prerequisite: STR 15 or Higher, Character Level 4 or Higher
You excel in close-quarters combat. You gain these benefits:
• You have advantage on checks made to initiate or escape a grapple and advantage on attack rolls against creatures you are grappling.
• When a creature starts its turn grappling or being grappled by you, it takes bludgeoning damage equal to your STR modifier.
• As an action, you can attempt to twist a creature you are grappling into a dangerous position. Make a STR (Athletics) check contested by the grappled target’s STR (Athletics) or DEX (Acrobatics) check. If you succeed, the target is restrained until the grapple ends.
