How to Breathe Underwater in Minecraft 1.13: The Ultimate Guide

Mastering aquatic exploration in the blocky world of Minecraft is essential for anyone looking to uncover the secrets of the deep. While the base game does not allow you to breathe indefinitely underwater, version 1.13 provides several effective methods to extend your dive time and navigate the ocean's depths. This guide details the mechanics and best practices for staying submerged, whether you are searching for ancient cities or building an underwater base.

Understanding the Breathing Mechanic

The core limitation players face is the oxygen bar, which depletes when you are submerged and refills only when your head is above water. Inversion potions can temporarily hide this bar, but they do not actually grant the ability to breathe; entering the water while they are active will still cause drowning after a few seconds. Therefore, the goal is to manipulate the environment or use equipment to circumvent the standard oxygen depletion cycle.

Utilizing the Conduit Power Effect

Building a Conduit

The most sustainable method to breathe underwater is to activate a Conduit. This block provides the "Conduit Power" effect, which grants water breathing, night vision, and a significant mining speed boost. To activate it, you must construct a frame around the Conduit using Prismarine, Dark Prismarine, Sea Lanterns, or Prismarine Bricks.

Frame Requirements

To unlock the full potential of the Conduit, the frame must be completely surrounding the block with a specific pattern. The smallest valid frame is a 3x3x3 cube of the prismarine materials, with the Conduit placed in the center. Once activated, you can swim anywhere within the water source blocks that make up this structure and breathe indefinitely.

Potion and Equipment Strategies

Water Breathing Potions

Brewing a Water Breathing potion is the most direct way to bypass the oxygen mechanic. Created using a Pufferfish and a Nether Wart, this potion extends the player's breath bar significantly. For longer durations, you can combine it with Redstone to create an extended version, allowing for thorough exploration without constant surfacing.

Turtle Shell Helmets

A more organic approach involves utilizing the Turtle Master mob. When killed, this creature drops Scute items, which players can use to craft a Turtle Shell helmet. Wearing this helmet provides the "Respiration" effect, which extends breath time by 15 seconds per level when you start drowning. This is a passive solution that works in any body of water.

Cheating the System with Commands

For players using Java Edition or single-player worlds, commands offer a shortcut to survival mode underwater. By opening the chat window and typing `/give @p minecraft:water_bottle`, you can obtain a lingering potion that applies Water Breathing to anyone who enters the area. Alternatively, using the `/effect` command can directly apply the breathing effect to your player entity.

Enchantments for Underwear Survivability

Respiration Enchantment

Found on helmets, the Respiration enchantment is specifically designed for underwater survival. It uses the Rarity tier system (I, II, III) to determine how much longer you can hold your breath. Obtaining this enchantment on a helmet should be a priority for any player planning frequent oceanic expeditions.

Protection Enchantments

While not directly related to breathing, Protection and Blast Protection enchantments are vital for surviving the physical hazards of the deep. These protect you from the damage caused by Guardians, which inflict heavy Mining Fatigue, making it difficult to break blocks even if you have air. Mitigating this damage allows you to focus on navigation rather than defense.
