An addon for KubeJS that allows for creating custom spells, spellbooks, and more from Iron's Spells 'n Spellbooks.
Quick answer
Which KubeJS Iron's Spells release should I use?
KubeJS Iron's Spells 6.5-3.14-r2 targets 1.20.1 with Forge. Installation on the client is optional. Installation on the dedicated server is optional. 1 required mod needs a matching file.
Where it goes
Is KubeJS Iron's Spells required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does KubeJS Iron's Spells 6.5-3.14-r2 need?
6.5-3.14-r2. Change the file and its required mods may change too.
Install Iron's Spells 'n Spellbooks, KubeJS, Architectury API, Rhino first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match. 2 come through another mod in the chain.
2 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.
