Mystical Index

# Mystical Index — 1.20.1-1.3

**Minecraft:** 1.20.1 · **Loader:** Fabric · **Requires:** Fabric API, MidnightLib · **Optional:** Roughly Enough Items (REI)

A big storage-and-polish release: a new network storage terminal, tiered storage books, full REI support, and a deep bug-fix pass across the whole mod.

---

## ✨ New

**Mystical Lectern** — a storage terminal for your Libraries.
- Craft a vanilla Lectern with a Library to make one.
- Opens a screen that shows the combined contents of **every Library in range** as one scrollable, searchable list with running totals.
- **Search box** to filter by name, and an **A‑Z / count** sort toggle.
- Left‑click pulls a stack, right‑click half, shift‑click sends a stack straight to your inventory.
- Built‑in **3×3 crafting grid** that auto‑refills consumed ingredients from the network — shift‑craft to mass‑produce straight out of storage.

**Books of Holding (I–IV)** — tiered, upgradeable storage books.
- Hold many item **types** at once (10 / 20 / 30 / 40 types, at 1 / 2 / 4 / 8 stacks each — all configurable).
- Auto‑collect item types they already hold, right‑click to withdraw, sneak‑right‑click to deposit matching items.
- Drop empty ones in a Library and they become general storage cells.
- Upgrade in place with gold → diamond → netherite, keeping their contents.

**Roughly Enough Items (REI) support.**
- Recipes shown for Book of Holding upgrades and for every Entity Paper → Spawn Egg conversion.
- A **Piston Crafting** category documenting the piston recipes and the hostile‑book charging mechanic.
- REI's **Move Items (+)** works at the Lectern — it fills the grid from your inventory *and* your Library network, and greys out when you can't afford the recipe.

**Cleaner tooltips.** Every storage book now shows a compact per‑type icon grid with totals instead of a wall of slots.

## 🐛 Bug fixes

- Fixed a crash that prevented the mod from running on **dedicated servers**.
- Fixed a crash when viewing **Entity Paper** bound to a missing/removed entity.
- Fixed a crash/filter‑bleed when hovering a **Book of Magnetism**.
- Fixed tooltip crashes on villager books in some inventory screens.
- **Books of Storage/Holding no longer lose items** to storage pipes that probe them, to over‑stack inserts, or when a capacity config value is lowered.
- The **Library screen** now closes properly when you walk away or the block is broken (books can no longer be lost into a broken Library).
- **Placing blocks** from a Book of Storage no longer overwrites chests/containers without dropping them, and places blocks in the correct orientation.
- Upgrading a full **Book of Holding** no longer scrambles its stored item types.
- **Villager books** no longer copy live villagers when trading, no longer allow unlimited trades, and no longer duplicate through the Baby Villager Book recipe. Baby books keep the exact villager you captured and no longer grow up instantly.
- **Fluid books** stop overwriting their own custom name every tick (anvil renames stick).

## ⚖️ Balance & exploits

- Charging a Hostile Book with Entity Paper under a piston is now **kill‑capped** and consumes only the paper it credits (no more wasting a stack for one kill).
- The **Farming Book** now respects claim/spawn protection and drops the crop it harvests; you can unbind it.
- **Generating‑book cooldowns** no longer stall at each in‑game day, and cooldowns above ~20 minutes work as configured.
- **Kill tracking matches by mob type**, so name‑tagged mobs now count.
- Fixed **Ghast Paper** producing a zombie, and added the missing Entity Paper → Spawn Egg crafting recipe.
- Config changes now take effect without a restart.

## 🌐 Other

- The in‑game **config screen** and all book tooltips/messages are now translatable (proper labels instead of raw keys), with several typos fixed.
- Internal cleanup and a corrected Mod Menu icon.
