Wondrous Item, uncommon (requires attunement)
While wearing these bracers, you gain a +2 bonus to AC if you are wearing no armor and using no shield. These bracers are coated in a blue/green nacre and have 7 holes along the outer edge. Members of the military use these as means of long distance communication even underwater.
Notes: Bonus: Unarmored Armor Class, Warding, Wristwear
definitely interesting. I would elaborate further as to how they can be used as communication. And I would change the rarity to Rare at the least. a +2 to AC for a monk, barbarian, or spellcaster is kinda nuts for an uncommon item. But I really like the idea of them.
