This magical shield gives you a +3 bonus to AC and has a large stop sign on the front. Whenever a creature misses an attack against you while you are holding this shield and using it’s bonus to AC, the shield yells “NOPE!”. Every creature within 20 feet of you has to make a DC 18 Constitution save or take 4d10 thunder damage and be stunned. Once a day, you can use an action to press a button on the back of the shield and send the stop sign on the front flying towards your foes. Each hostile creature within 5 feet of you has to make a DC 15 Dexterity saving throw or take 6d10 bludgeoning damage and fall prone. If they succeed the save, they take half damage and don’t fall prone.

Shields require the Utilize action to Don or Doff. You gain the Armor Class benefit of a Shield only if you have training with it.
