Ice Shield

The Aquatic Heart is a 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).

Notes[]

  • It can be considered an upgraded version of Neptune's Shell.
  • Changing the accessory to "Hidden" will make the player look normal; however, the Ice Shield will still be visible.
  • A male character will always appear and sound like a female character while this accessory is visible. Despite this, NPC messages and death messages are not affected.
  • The character emits pale blue light while the Ice Shield is active, and orange light when it is recharging.
  • The damage reduction provided by the Ice Shield is calculated separately from typical damage reduction. As a result, it is not affected by the Calamity Mod's DR soft cap.

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.
