Soul Speed

Soul Speed is an enchantment that can be applied on boots and allows the player to walk quicker on soul sand and soul soil blocks.

Obtaining
Soul Speed can be acquired only via bartering with piglins, who may offer enchanted books and iron boots with Soul Speed. Piglins may spawn wearing golden boots enchanted with Soul Speed which have a chance to drop when they are killed.

Soul Speed is a treasure enchantment, and thus cannot be obtained from enchanting in an enchanting table. Unlike other treasure enchantments, it cannot be obtained from chest loot, fishing, or trading.

Speed
When walking on soul sand or soul soil, Soul Speed increases the player's speed, where soul sand would normally decrease the player's speed. When wearing boots with Soul Speed, the speed of the player is determined with. The speed decrease of soul sand has no effect on Soul Speed, meaning that the player can walk on soul sand with the same speed as on soul soil.

The speed of walking on soul sand or soul soil can be accelerated by having one layer of water on top of it, with the maximum speed soft-capping at about 550 to 750 blocks per second. Swimming underwater with soul sand or soul soil below the player can further accelerate the player, to a soft cap of about 750 to 950 blocks per second.

However, the Depth Strider enchantment completely negates the acceleration in both cases.

Theoretically one can utilize this method to reach a speed of about 1200 blocks per second before the game cannot load chunks fast enough, though this may vary a lot depending on the hardware.

Durability
The durability of worn boots enchanted with Soul Speed has a 4% chance to go down for each compatible block stepped on.

Particles
Soul particles appear when walking on one of the compatible blocks.

General
The tag determines which blocks are compatible with Soul Speed.
