Aquatic Heart

The Aquatic Heart is a Revengeance Mode Pre-Hardmode accessory dropped by ???. Equipping it transforms the user into a water elemental and causes them to emit light. After Skeletron is defeated, they gain a wide variety of bonuses including:
 * Improved underwater breathing ability
 * The ability to move through water unhindered, and the Ocean's Blessing buff while submerged which boosts underwater movement speed even further.
 * Nearby enemies are inflicted with the Glacial State debuff when the player is hurt; the duration and range of enemies that are inflicted scales with damage taken.
 * An Ice Shield which absorbs 20% of damage from hits (with a cooldown of 30 seconds).

Tips

 * To safely obtain the item in Pre-Hardmode without dying, use a Recall Potion after killing ???. Recall Potions have no delay and will guarantee your survival.

Trivia

 * Talking to the Sea King and Drunk Princess with the Aquatic Heart equipped will display a unique quote.
 * This was formerly two items known as Siren's Hearts, which could be either blue or green.
 * Only the green heart was considered to be gamagamer's Developer item, as they insisted on adding the green variants for this item as well as the Siren itself.
