Superior Spellcasting allows all mobs to become Iron’s Spellbooks casters.

As you defeat bosses from Iron’s Spellbooks, you increase the world’s Power Level up to a maximum of 10. As Power Level rises, the mod scales up in difficulty by increasing:

  • 🔮 the chance for mobs to gain spellcasting AI
  • ⚔️ the spell levels and rarities mobs can cast
  • ⚡ how often mobs can cast spells

🧙 By default, Power Level is tied to world progression. The mod tracks the first time these Iron’s Spellbooks bosses are killed:

  • Necromancer
  • Archevoker
  • Ice Spider
  • The Dead King
  • Echo of Tyros, First Flamebearer

Each of these bosses increases Power Level by +2 the first time it is killed, up to the cap of 10.

📈 Power Level is clamped from 0 to 10 and maps to mage tiers like this:

  • 0-1: Lesser
  • 2-3: Greater
  • 4-5: Adept
  • 6-7: Superior
  • 8-10: Grandmaster

🌊 If T.O Magic 'n Extras is installed, mobs can also cast spells from the Aqua school.

🪨 If GTBC's Geomancy Plus is installed, mobs can also cast spells from the Geo school.

🛠️ If you want custom scaling, or want to force a specific Power Level, you can do that with KubeJS.

Create a file named kubejs/server_scripts/superior_spellcasting_power.js and paste in the following:

// Superior Spellcasting global power setting
// Change only the number on the powerLevel line.
// Valid values: 0 to 10


ServerEvents.loaded(event => {
let KubeJsBridge = Java.loadClass('com.alexh.superiorspellcasting.integration.kubejs.KubeJsBridge')

let powerLevel = 6 // Change this number

KubeJsBridge.setOverride(event.server, powerLevel) })
