Enchanted Book Trader

Ever found an enchanted book you didn't need, with no good way to use it? This mod turns that book into currency — and turns your local librarian into an actual book dealer.

How it works

Teach a trade: Right-click a librarian villager while holding an enchanted book. The villager consumes the book and adds a real trade to its offer list — you (or anyone) can buy that exact book back from it later for emeralds.

Reroll for a better price: Got a duplicate of an enchantment type the villager already knows? Hand it over, and instead of teaching a new trade, it rerolls the existing one — new random price, the offered book updates to match the level you just gave it, and its stock fully restocks. It's a gamble each time.

Only librarians deal in books. Other professions (and unemployed villagers) will ignore the book entirely — it stays safely in your hand.

Details

• A single villager can learn up to 5 different enchantment types, each as its own trade slot
• Books with multiple enchantments (e.g. from custom NBT) aren't accepted, to keep pricing predictable
• Fully server-side gameplay logic — no client-only rendering, works in singleplayer or on a dedicated server

Requirements

• Minecraft 26.2
• Fabric Loader 0.19.3+
• Fabric API 0.155.0+26.2 or newer

Compatibility

Doesn't touch vanilla villager profession trades — every trade this mod creates is internally tagged so it only ever modifies its own entries, even on a librarian that already offers books natively.
