Wondrous Item, Uncommon (requires attunement)
Aura: Minor Enchantment
This medallion was created to foster diplomatic negotiations between underwater races. While you wear this amulet, you have advantage on all Charisma checks directed at creatures that are naturally able to breathe underwater. This amulet has no effect on creatures that have been given the ability to breathe water from a spell or other magical effect.
