Drowning occurs when a player's breath meter fully depletes while submerged in water or honey. While drowning, the player will take continuous damage until they are able to successfully counter it with an accessory, a potion, or a pocket of air. Otherwise, the player will eventually die. The rate at which drowning occurs cannot be slowed down nor sped up, unless the player has certain accessories equipped.

NPCs can also drown if stuck or forced underwater, making this a very effective way of killing NPCs. Notably, house validity is not affected by liquids, meaning they can be 'automatically' drowned by flooding their house. The only NPC that is immune to drowning is the Skeleton Merchant(Desktop, Console and Mobile versions), although the Nurse can heal herself fast enough to avoid drowning.

Drowning may happen at any place with large enough bodies of water or honey to fully submerge the player, with Oceans and Bee Hives being prime natural candidates for such an event. Equipping a Fish Bowl can be used to manually drown the player. Lava can never drown the player; it deals damage on contact instead.

  • The Flipper and its upgrades allow players to swim. This greatly aids underwater travel and usually greatly reduces the likelihood of drowning. A hook can be used alternatively, if there are other types of solid terrain nearby.
  • The Water Walking Potion or the Water Walking Boots and its upgrades allow walking on the surface of liquids, preventing accidental drowning. However, it is still possible to sink.
  • Due to the reduced movement speed in honey, a player could get stuck and easily drown in honey if they do not have proper equipment.


  • Dying from drowning will display one of the following unique death messages:
    • "<Player name> forgot to breathe."
    • "<Player name> is sleeping with the fish."
    • "<Player name> drowned."
    • "<Player name> is shark food."
    • "<Player name> tried to drink a lake."
    • "<Player name> discovered Atlantis."
    • "<Player name> forgot to bring a towel."


  • Desktop 1.2:
    • Lava no longer causes drowning.
    • Honey introduced, and can drown the player.


  1. A tick is a time unit countable by the software. Most of Terraria's updating logic happens every tick. A tick has the length of 1/60th of a second, hence there are 60 ticks in a second and 3600 ticks in a minute.
