KJ's Skill Tree
by itspixl7
KJ's Skill Tree adds a Fabric skill tree for combat, gathering and tool progression, which players advance through as they play the 1.21.1 game.
What it does
The tree splits into two branches that the player advances through in order: a combat tree with three classes that suit different playstyles, and a gathering tree that gates tools behind earlier steps while boosting mining speed and fortune and lowering anvil repair costs. It is built on Pufferfish Skill Trees and Pufferfish Attributes, and the author recommends pairing it with a difficulty mod to scale mobs. Installation covers the server and each player's game. Only Fabric files exist, for 1.21.1.
Key features
Combat classes
Three combat classes let players build different playstyles through the combat tree, with stronger attacks than vanilla mobs expect.
Gathering progression
Tools are locked behind gathering steps, with buffs to mining speed and fortune and cheaper anvil repairs.
Pufferfish-based tree
The trees are built on Pufferfish Skill Trees and Pufferfish Attributes, and the author ships them as part of KJ's Progression Pack.
