Magic Schools Skill trees: Addon for Iron's Spells 'n Spellbooks Unofficial Skill Tree
Java mod listed for Minecraft 1.19–1.21. Downloads from the MC Java Mods app on Android.
This mod adds a skill tree for each magic school present in Iron's Spells, it's meant to be used with "Unofficial Iron's Spells 'n Spellbooks Skill Tree"
I don't know my version or loader








This addon adds a skill tree for every magic school that is present in Iron's Spells and Spellboks, you can get levels in them alongside the "main tree", all spells will contribute to the main tree but only give XP to their respective school, so for example if you use a fireball you'll get XP in the main Magic tree and in the Fire school tree but not in the Ice school tree
There's two versions, the normal one gives you a 30% boost to that magic school spell power once you get every skill in the tree while the OP version gives you a 90% boost once you get every skill in the tree, if you started with one version and didn't like it you can download the other one (but make sure to only have one version at a time) and you'll keep the progress of the tree and the only thing that will change is the boost you get
Feel free to do anything you want with this mod, include it in your modpacks, modify it and reupload your own version, whatever lol
