While wearing these armwraps, you gain a +1 bonus to your Unarmored Defense AC.

In addition, whenever you are hit with an attack that deals Acid, Cold, Fire, Lightning, or Thunder damage, you can use your reaction to cast Absorb Elements at 2nd Level, lessening the attack. Then, whenever you make an Unarmed Strike, you can unleash the stored power into your attack, dealing an extra 2d6 of the triggering type of damage. After you unleash the stored power, you no longer have resistance to that damage type. Once the armbands have been used in these ways, these properties cannot be used again until next dawn. 

Notes: Damage: Unarmed Attacks, Bonus: Armor Class, Requires Attunement by a Monk
