Armor of Retribution

While wearing this armor, you have a +1 bonus to AC. 

Whenever a creature missies a melee attack against you, or an ally with in 5 ft. of you, then as a reaction they must make a DC 15 strength saving throw. On a failed save, the creature takes 3d8 force damage and is knocked prone. On a successful save, the creature takes half as much damage and isn't knocked prone.

Made from tough but flexible leather, studded leather is reinforced with close-set rivets or spikes.
