Turtle Shell

"Turtle shells are a wearable item that let players breathe a little longer underwater. Wearing a turtle shell in a helmet slot, while out of water or in a column of bubbles, will give the player a "water breathing" status effect, which only starts counting down when the player submerges. I guess the extra air is stored in the top of the shell somewhere, but who knows how those turtles weave their bubbly magic?"

- Duncan Geere

Turtle shells, referred to as turtle helmets in the game’s code, are items that are used for brewing or as a helmet to give the player the Water Breathing status effect.

Usage
Like helmets, turtle shells can be placed in the top armor slot of a player's inventory for activation.

Equipping
If a player is wearing a turtle shell in their helmet slot while out of water or in a bubble column, they will receive Water Breathing for 10 seconds (in Bedrock Edition the water breathing effect only activates when in air, not bubble columns). This effect won't start counting down until the player goes underwater. This essentially gives the player 10 extra seconds of breath underwater.

Equipping a turtle shell will also provide the player with defense points, which is the same amount of defense that golden, chain, and iron helmets offer (however, diamond helmets offer ). This means that for damage done to the player while wearing a turtle shell, 8% of the damage will be absorbed by the turtle shell.

Turtle shells have 276 durability, which is more than any type of armor except for diamond.

Repairing
Turtle shells can be repaired with scutes using an anvil.
