A basic skill tree mod intended to be used alongside the RPG Series of mods. It uses the spell power attribute and as such Spell Power Attributes is a dependency.
All of the different skill trees have different ways that you level them up and different attributes to increase:
To be honest, I mostly made it for my personal use in a private modpack. I'm uploading it because I've noticed that other skill tree mods are either incredibly unbalanced or incompatible with ZsoltMolnarrr's RPG Series (or both). If you wanted to use all of his RPG mods, you either couldn't use any skill trees other than the dedicated RPG Series Skill Tree (which is meant to be used alongside this), or have all the non-magic classes be stronger than the magic focuses classes. This mod offers a decent middle ground by not having the tree be so large and overpowered and also including the spell power as something to be upgraded in one of the skill trees as well.
Although it is labeled for Fabric 1.21.1, this is essentially a datapack compiled as a mod, so it may be able to work on other pre-1.21.2 versions. (This isn't guaranteed tho, I'm simply saying that this was only made and tested for 1.21.1)
