Soul Alchemy
by TheNope_
Soul Alchemy lets a player adjust their own attributes through Soul Points and Soul Shards, using tome items and a datapack-based system.
What it does
The mod began as a datapack for survival worlds that lets a player change attributes such as max health, speed and attack. Later versions added changes that work on nearby items and objects. Attribute changes are made with Soul Points and Soul Shards, a currency that cannot be renewed and is not consumed when used.
Its main item is a set of tomes. Tome Power raises the attack attribute, Tome Speed raises speed, Tome Agility raises jump height and Tome Heart raises max health. Tome Insight shows a player's current stat allocation, and the Knowledge Tome explains how to use the custom crafter pack. Soul Alchemy itself lets a player permanently disable or activate potion effects and disable the ability to use certain items.
The server must run Soul Alchemy, while players may leave it out. Files are published for Fabric, Forge, NeoForge and Quilt, each targeting 1.21.4 with version 1.0.1+mod dated 2025-12-03. The mod is released under the MIT License and is not open source. The author notes that balancing is still in progress and that outside testers are being sought to help.
Key features
Permanent attribute changes
Soul Points and Soul Shards allocate attribute changes that stay on the player, with allocation freely adjustable.
Stat tomes
Separate tomes raise attack, speed, jump height and max health, each acting on one attribute.
Stat insight
Tome Insight displays the current stat allocation so players can check what they have invested.
Potion and item toggles
Players can permanently disable or activate potion effects and disable the use of certain items.
Nearby object changes
Later datapack updates let players modify items and objects close to them, not only their own stats.

How it compares
Enchantment Tomes is also a server-required, client-optional mod under the MIT License, published for 1.21.4 – 26.3 on Fabric, Forge, NeoForge and Quilt, and it uses tomes for enchantments rather than stat changes. Attribute Accessories covers 1.21.11 – 26.2 and is released under the GNU General Public License v3.0 or later, so it does not overlap in version range with Soul Alchemy. RPG Style Player Stat Progression/Levels is MIT licensed and targets 1.21.4 – 1.21.11, matching this mod's version and offering a levelling approach to stats.
