Morphing Bracelet
The Morphing Bracelet gives players the ability to morph into different mobs. Simply kill a mob while keeping a bracelet in your inventory to collect its soul and morph into it. To craft this item, you need four Soul Soil blocks and one Soul Glass block.

Morphing Bracelets have durability, and every time you morph into a mob, it consumes some of the bracelet's durability. To repair it, hold your bracelet and stand on Soul Sand or Soul Soil to harness their energy.

Soul Glass
Soul Glass is an "active" variant of Soul Sand, obtainable by smelting Soul Sand in a furnace. It produces a very faint glow in the dark and can be used as a decorative block in builds. It is one of the key ingredients for the Morphing Bracelet and serves as the main energy source for morphing.

Soul in a Bottle
An item that can contain a mob's soul, allowing you to morph into it. You can store a collected soul in an empty bottle (Soul Glass Bottle), allowing players to trade mobs with each other.

To use this item, morph into the desired mob and use the bottle to store the soul of the mob you are currently morphed into. The mob type stored in the bottle is indicated in the item's tooltip.
WARNING: The add-on heavily modifies the player.json file in the behavior pack and the player.entity.json file in the resource pack. This means that any add-on or resource pack that modifies these files could break this add-on. It is not recommended to install this add-on with other add-ons in the same world, as the Morphing Bracelet is not a "modpack-friendly" add-on.
