Armor of Reverberation

Medium Armor made from the tough skin of a bugbear. This provides 12 AC, and you add your Dexterity modifier (Max 2) to the AC. When a creature makes a bludgeoning attack roll on you and fails, they must make a Dexterity saving throw with a DC worth your AC or else drop their weapon. If they drop it they must spend one action to pick it up. If you encounter a bugbear while wearing this, the bugbear must make a Constitution saving throw against a DC of your AC or they become frightened. They cannot move willingly towards you and have disadvantage on ability checks and attack rolls while you are in sight. 

This crude armor consists of thick furs and pelts.
