Spell Codex: Iron's Spells 'n Spellbooks Addon

Spell Codex is a progression addon for Iron's Spells 'n Spellbooks. Spells are discovered into a Spell Codex, unlocked tier by tier with XP and ink, then equipped on a Spell Actionbar. You cast only what you have earned — from Iron's base schools and compatible school addons.

Requires Iron's Spells 'n Spellbooks and Spell Actionbar 1.1.6+.

The loop

1. Discover spells into your Codex
2. Open the Codex with the Spell Actionbar key (default `)
3. Select matching ink, then press + to unlock the next tier
4. Click an unlocked spell, choose a tier if asked, and place it on the action bar
5. Cast from the action bar only

A built-in Guide (? beside the Codex) walks through each step with live illustrations. Progress bars under the Codex track school and overall discovery.

---

Discovering spells

• Empty Codex Page — Arcane Anvil: paper + Iron's ink (attuned to that rarity)
• Scroll Forge imprint — hold a school focus and a blank page in your hands, then use the forge (costs XP). Stronger ink blanks can imprint rarer spells
• Codex Pages — right-click to learn; found in adventure loot, and converted from Iron's scroll drops
• Leftover Iron's scrolls — right-click to absorb into the Codex
• Filled spellbooks — sneak + right-click to learn inscribed spells and empty the book; equip the empty book in Curios for more action bar slots

---

Spell Codex

• School tabs and a grid of discovered spells
• Action bar slots follow your equipped empty Curios spellbook (default 3 with no book)
• Horizontal scrolling for wide books and long school lists
• Ink slots under the panel for tier unlocks
• School / overall discovery progress bars
• Edit HUD — reposition the action bar + mana group and the cast/charge bar
• The action bar HUD stays hidden until at least one spell is equipped

---

Unlocking & casting

• + unlocks the next tier in order; costs XP and one matching rarity ink
• Hold a matching school focus for a 25% XP discount (ink still required)
• Respec refunds a configurable share of spent XP
• Casting is actionbar-only — Iron's wheel, books, inventory scrolls, and imbued weapons cannot cast for players
• Only unlocked tiers of discovered spells can be cast

---

What Specs changes

• Iron's scroll crafting is removed; spellbook crafting stays
• The Scroll Forge imprints Empty Codex Pages instead of crafting scrolls
• Scroll loot/drops become Codex pages; pages recycle in the Alchemist Cauldron for ink
• Spellbooks still craft, drop, and toss normally (empty before equipping for bar slots)
