Iron's Attributes

Add individual attribute requirements for every spell from Iron's Spells 'n Spellbooks!

Features

  • Individual Spell Attributes - Each spell has its own unlockable attribute
  • Rarity-Based Locking - Lock/unlock entire spell rarities at once (Common, Uncommon, Rare, Epic, Legendary)
  • School-Based Locking - Lock/unlock entire spell schools at once (Fire, Ice, Lightning, Holy, Ender, Blood, Evocation, Nature, Eldritch)
  • Configurable - Enable/disable locking per spell, per rarity, or per school
  • Addon Support - Automatically detects spells from addon mods (Cataclysm Spellbooks, etc.)
  • Auto-Generated Reference - Creates a list of all attribute IDs for easy command setup

How It Works

Players must have the appropriate attribute level to cast each spell. Attributes are automatically generated for all spells from Iron's Spells 'n Spellbooks and compatible addon mods.

By default, all spells and rarities are locked (attribute value = 0). Players cannot cast spells until their attributes are set to 1.

School locking is disabled by default and can be enabled in the config.

Usage

Unlocking Spells with Commands

Use vanilla Minecraft's /attribute command to unlock spells for players:

Command Description
/attribute @p ironsattributes:irons_spellbooks_fireball_unlocked base set 1 Unlock Fireball spell for yourself
/attribute @p ironsattributes:irons_spellbooks_ice_block_unlocked base set 1 Unlock Ice Block spell for yourself

config.json

{
  "globalSpellLocking": true,
  "globalRarityLocking": true,
  "globalSchoolLocking": false,
  "schools": {
    "irons_spellbooks:fire": false,
    "irons_spellbooks:ice": false,
    "irons_spellbooks:lightning": false,
    "irons_spellbooks:holy": false,
    "irons_spellbooks:ender": false,
    "irons_spellbooks:blood": false,
    "irons_spellbooks:evocation": false,
    "irons_spellbooks:nature": false,
    "irons_spellbooks:eldritch": false
  },
  "rarities": {
    "common": true,
    "uncommon": true,
    "rare": true,
    "epic": true,
    "legendary": true
  },
  "spells": {
    "irons_spellbooks:fireball": true,
    "irons_spellbooks:heal": true
  }
}
Option Description Default
globalSpellLocking Master toggle for individual spell locking true
globalRarityLocking Master toggle for rarity-based locking true
globalSchoolLocking Master toggle for school-based locking false
schools.&lt;school_id&gt; Enable/disable locking for specific school false
rarities.&lt;rarity&gt; Enable/disable locking for specific rarity true
spells.&lt;spell_id&gt; Enable/disable locking for specific spell true

Set any value to false to disable locking (spell becomes available to everyone without needing the attribute).

To enable school locking, set globalSchoolLocking to true and set the desired schools to true. When a school is locked, players must have the school attribute set to 1 before they can cast any spell from that school.
