Apotheosis x Iron's Spellbooks Compat
An addon creating integration between Apotheosis and Iron's Spells n' Spellbooks, adding new affixes, gems, and other compatibility for spellcasters of all kinds.

Features:
- Adds 2 new reforge/loot categories, Staffs, applicable to any item extending Iron's Spells n' Spellbooks'
CastingItem, and reforgable Spellbooks. These items can receive new affixes specific to spellcasting. - Attribute Affixes like "+X% Fire Spell Power". These are intelligently filtered - gear will only receive affixes matching the spell school(s) detected from its existing attributes (e.g., a staff with Fire attributes can roll Fire affixes, but not Ice affixes). Supports items with multiple schools and upgrade orbs.
- "Spell Effect" Affixes, similar to Apotheosis' Mob Effect affixes, but triggered by spell actions: On Spell Heal (Self/Target) and On Spell Damage (Self/Target).
- "Cast Spell" Affixes, automatically cast a spell for no mana (the affix itself has a cooldown), triggered on melee attack, ranged attack, spell damage/heal, or when attacked (based on the type of gear).
- "Spell Level" Affixes, increase the level of spells for a spell school. Like attribute affixes, these are filtered by school to only apply to gear with matching attributes.
- "Mana Cost" Affixes, decrease the mana cost of spells for a spell school. Also intelligently filtered.
- Adds a Telepathic affix for staffs, and adds special compatibility for mob drops to teleport to you when slain by magic.
- Introduces several new Gems themed around various spell schools, providing spell power, resistances, and other thematic bonuses.
**Only for NeoForge, 1.21.1. No backports will be made.
**(but 1.20.1 Forge players might like Fallen Gems & Affixes!)
Compatibility:
Built-in optional support for several Iron's addons, adding gems and affixes for their custom schools and spells:
- Abyssal and Sand schools from Cataclysm Spellbooks
- Melody school from Tunes n Tomes
- Wind school from SnackPirate's Aeromancy Additions
- Symmetry and Spirit schools from Magic From The East
- Radiance and Shadow schools from Hazen n' Stuff
- Hydro and Technomancy schools from Ace's Spell Utils
- Aero and Necro schools from Monsters Spellbooks
- Occult school from Discerning the Eldritch
- Spellblade school from Ender's Spells and Stuff Requiem
If you don't see your addon on this list, feel free to submit a PR or a feature request on Github. You could also bundle the affixes/gems yourself (somewhat preferred, as maintaining compat for so many other addons will become time consuming) - If you need help with that, ask on Discord!
