Celestial Skill Tree

Celestial Skill Tree is a mod that transforms your progression into a map of the night sky. Each class is a constellation, each skill is a star, and the entire tree is generated based on your specific world—meaning no two worlds will ever have the same tree!

Spend your experience on skill points, plan a route across the stars, and build the character you want.

Features

• 6 classes: Duelist, Guardian, Arcanist, Marksman, Artificer and Berserker
• A 7th class, the Mage, when Iron’s Spells ‘n Spellbooks, Ars Nouveau or Malum is installed
• Up to 100 skills per class, each with a real effect
• Keystones that give a big advantage with a drawback
• Ranked skills with up to 5 ranks
• A different tree in every world, generated from the seed
• 12 birth signs with a small permanent bonus
• Falling stars, star showers and eclipses
• Constellated monsters
• Fully data-driven, with KubeJS support
• And much more!

– The Star Chart –

Press O to open the chart. Buy points with your XP, pick a starting star and grow outward: every skill has to
connect to one you already own. Nothing is applied until you press Confirm, so you can plan a whole route,
undo and redo before spending anything.

– Strange Stars –

Not every star is a simple bonus. Gates link opposite sides of the map, black holes make the skills around
them stronger but seal the rest, and some keystones come in exclusive pairs: take one and the other is locked.

– The Living Sky –

At night, falling stars cross the sky and leave a Star Fragment where they land, worth one skill point. Some
nights bring a star shower. Some days the moon covers the sun for an eclipse: monsters walk in daylight,
undead don’t burn, but respecs are free until it ends.

– Constellated Monsters –

Rarely, a monster spawns carrying a small constellation of its own. It is tougher than usual and drops a
Star Fragment when a player kills it.

Getting Started

Press O (rebindable) to open the star chart. Press H inside it for the list of controls.

FAQ

Q: Can I use this mod in my modpack?
A: Yes! Just keep the credit and don’t reupload the jar.

Q: Fabric / Forge / older versions?
A: Not planned. NeoForge 1.21.1 only for now.

Q: Can I change the skills?
A: Yes. Classes, skills, keystones and rules are JSON files in a datapack. /celestialskilltree validate shows
exactly which file and field is wrong.

Q: Is it multiplayer friendly?
A: Yes. The server validates every purchase, and the server config controls prices, caps and every bonus.
