Soul Speed

Soul Speed is an enchantment to boots that allows the player to walk quicker on soul sand and soul soil. Enchanted books and iron boots with this enchantment can be acquired through bartering with piglins.

Usage
When on soul sand or soul soil, Soul Speed will increase the player's speed. The speed the player is equivalent to setting the block's speed factor to. The block's base speed factor has no effect on Soul Speed, meaning the player will travel the same speed on soul sand and soul soil. The durability of worn boots enchanted with Soul Speed has a 4% chance to go down for each compatible block stepped on.

The tag determines which blocks are compatible with Soul Speed.
