Rerollager

A lightweight Paper plugin for rerolling villager trades. Sneak and right click a villager to refresh its trades on the spot, with no breaking and replacing the workstation. Keep rerolling until you get the enchanted book, tool, or price you want.

Made for the latest Minecraft. No dependencies. MIT licensed.

What it does

In vanilla you can only reroll a villager's trades before you have traded with it, and the usual trick is to keep breaking and replacing its lectern or workstation. Rerollager skips that. Sneak and right click an employed villager and its trades regenerate at its current level, keeping the same profession, level, XP, and name. It also works on villagers you have already traded with and leveled up, so you can reroll a maxed librarian without starting over.

Features

• Reroll trades in place with a sneak and right click. No workstation breaking.
• Keeps the villager's profession, level, XP, and custom name.
• Works on villagers you have already traded with, not just fresh ones.
• Optional cooldown, tracked per player and per villager.
• Optional cost per reroll: items, XP, or both, with optional scaling by villager level or profession.
• Trade locking so a villager cannot be rerolled by accident. Lock and unlock with a configurable item.
• Permission based. Nothing is granted to players by default, so you decide who can use it.
• Lightweight with no external dependencies.

How to use

1. Find or make an employed villager by placing a job site block next to it (a lectern makes a Librarian).
2. Sneak and right click it with an empty hand. Its trades reroll.
3. To lock a villager, sneak and right click it while holding the lock item (a Tripwire Hook by default). Do it again to unlock.

Out of the box only operators can reroll and lock. Grant rerollager.use (and rerollager.lock) to the players or groups you want to give access to.
