great having all the skills
FreeRPG is a spigot 1.15+ plugin that adds an RPG skill system to minecraft. Inspired by Mcmmo, the goal of FreeRPG is to offer a free Mcmmo alternative. Each skill has a skill tree, with an additional global skill tree. The skill trees can be accessed with a very simplistic, Hypixel inspired GUI accessed using /freeRPG.
I really like the changes it brings into the survival vanill gameplay, you can change them to your liking (more vanilla or more modded)
