Smash Attack (technique)

master technique — attack

Make an unarmed strike against a Small or Tiny creature. On a hit, the attack is automatically a critical hit and the target must make a Strength saving throw against 8 + your Strength modifier + your proficiency bonus. A Tiny creature has disadvantage on this saving throw.
     On a failed save, the target is sent flying up to 30 feet directly away from you. If the target's trajectory is stopped by a solid object, a Huge creature, or a Gargantuan creature, the punted creature stops against that object, lands prone, and takes 1d6 bludgeoning damage for every 5 feet it had yet to travel. The struck creature takes the same amount of damage.
