Powerful Shove Feat 4FighterSource Core Rulebook pg. 146 1.1Prerequisites Aggressive Block or Brutish Shove
You can push larger foes around with your attack. You can use
Aggressive Block or
Brutish Shove against a creature up to two sizes larger than you.
When a creature you Shove has to stop moving because it would hit an object, it takes damage equal to your Strength modifier (minimum 1). This happens regardless of how you Shoved the creature.
