Keystone Expansion — MMORPG Skill Trees Addon

Keystone Expansion is an MMORPG-inspired skill tree expansion for Puffish Skills, built to add long-term progression, build variety, and satisfying endgame power to survival modpacks.

This project adds multiple custom categories with large, interconnected trees and meaningful upgrades (health, resistance, stamina, luck, XP gain, mobility, damage, and more). The goal is a “hack & slash / MMO” progression feeling: early upgrades are subtle, but the more you invest, the more your character becomes noticeably stronger.

Main Features

9 progression categories:
- Combat
- Mining
- Exploration / Mobility
- Farming
- Crafting / Artisan
- Building / Architecture
- Magic / Alchemy / Enchant
- Taming / Companions
- lumberjack
MMO-style scaling: long-term leveling curves, endgame milestones and keystones
Synergy-focused trees: multiple paths and playstyles (tank, mobility, sustain, luck/XP, etc.)
Addon-friendly: made to be used inside modpacks and servers

Required Dependencies

This addon will NOT work without the following required mods installed:

Puffish Skills (Required)
Puffish Attributes (Required)

Compatibility

Designed for Forge/Fabric/Neoforge
Works as an addon for modpacks / servers using Puffish Skills

Notes

This project does not replace Puffish Skills — it extends it with additional categories and custom trees.
Balancing can vary depending on your modpack difficulty and progression speed.

Enjoy the grind — and the dopamine when your build finally pops off.
