Depth Strider is an enchantment in Minecraft that increases the players movement speed underwater. The enchantment can be applied to boots using an enchanting table, anvil, or a grindstone. There are three levels of Depth Strider, and each level reduces the amount of water that slows the player by 1/3.

The Depth Strider enchantment can be very useful for traversing underwater environments, such as oceans, rivers, and lakes. It can help players escape or dodge attacks from hostile mobs or players faster and can make traversal much easier. The enchantment also decreases the amount of resistance or slowness that is applied by the water to a players movement, including the amount of distance that the player is pushed across when a flowing body of water has contact with them.

Depth Strider III is the maximum level of the enchantment, and it allows the player to walk underwater as fast as they can walk on land. It also increases the speed at which a player swims. When combined with the "dolphins grace" status effect, which is given to players who swim close to dolphins, players can move very fast through a body of water.
