About this Mod
Skill Tree (Fabric)
Turn your Experience into Permanent Power.
Skill Tree (by JammingDino) completely overhauls how you view Experience Points in Minecraft. Instead of hoarding levels only to lose them in a lava pit, use them to unlock permanent passive abilities, stat boosts, and unique game-changing mechanics.
To get started, simply craft and place a Skill Altar, then right-click it to open the radial skill menu. From there, you can spend your collected Experience Points to unlock permanent passive abilities that persist even after death. These upgrades range from basic stat boosts and faster mining speed to unique mechanics like moving swiftly through lava or pulling enemies towards you with every hit. To access more powerful, higher-tier skills, you will simply need to upgrade your Altar to better materials like Iron, Diamond, or Obsidian.

- Skill Altars: Craft tiered Altars (Iron, Diamond, Emerald, Obsidian) to access the skill tree. Higher tiers unlock more advanced skills.

For Mod Developers: Built-in Editor
Skill Tree is 100% data-driven. This means if you want to create your own skills, you don’t even need to use JSON — you can simply use the built-in Developer Skill Altar block in-game to start building custom skills in real time.
- Place a Developer Skill Altar.
- Open the GUI to access the In-Game Skill Editor.
- Design your skill (Name, Icon, Cost, Prerequisites, Effects).
- Click Export.
- The mod handles the rest — generating the JSON files needed for your modpack or datapack.
Note:
"jd_skill_tree"is the internal ID for JammingDino’s Skill Tree mod.
If you plan to use this mod in a modpack/datapack, make sure to correctly mark Skill Tree (Fabric) as an optional or required dependency in your config files.

- Report Bugs: Please report any issues on the GitHub Issues page.
The mod is still in active development — expect features to be completely reworked or changed without warning. If you have ideas for new features, feel free to open an issue labelled “enhancement” or leave a comment on the GitHub page.
At the moment, the mod is geared toward use in modpacks or specialized projects, but I plan to gradually expand the set of default skills to be more generic and useful across a wide variety of modpacks.

Server lagging with Skill Tree – how to optimize performance?
