Auto Villager Reroll

Automates librarian lectern rerolls. Configure a list of desired enchanted books, then the mod will repeatedly break and replace a lectern until one of those books appears in the villager's trades.

Usage

1. Open the config screen — Press R (configurable in Controls → Miscellaneous → Open Villager Reroll).

3. Lock in trade (optional) — Toggle this on to automatically lock in the trade when a match is found.
4. Start — Click Start, then right-click a lectern. The mod will:
   • Open the trade and check the villager's offers
   • If no match, break the lecturn and place a new one from your invetory
   • Repeat until a match is found or you stop the mod

• Stop — Click Stop in the GUI, or the mod stops automatically when a match is found.
