Spellbook Eraser is a lightweight addon for [Iron's Spells 'n Spellbooks](https://www.curseforge.com/minecraft/mods/irons-spells-n-spellbooks) that adds a single powerful tool: the Spell Unbinding Quill.

By default, Iron's Spells locks certain spells to prevent removal - unique/preset spells on books like the Necronomicon, starter spells on fresh school spellbooks, or spells locked through the Arcane Anvil. This addon lets you remove those spells directly, using the mod's own public API with zero patches or mixins to the base mod.

Features

Remove Any Spell - including locked/built-in ones that the base mod's own GUIs hide.
Single-Item Design - just one tool to craft and use.
API-Only - uses Iron's Spells' documented addon API, no code patches.
Localized - English and Russian included.
Lightweight - tiny addon, no bloat.

Tutorial:

1. Craft a Spell Unbinding Quill:
- Feather + Ink Sac + Book → shapeless recipe
- Or find it in the creative tab (Ingredients)

2. Hold the quill in one hand and a spellbook/scroll in the other

3. Right-click:
- Normal: removes the last spell in the book (one at a time)
- Shift + Right-click: removes all spells at once, including locked ones

4. Done - the spells are gone, that's all!
