Build a 15-lamp lectern power bar and a vault that opens on one page only.
The Oracle's book holds 15 prophecies. Turn to the right page and a hidden vault grinds open.

What you’ll build
Write fifteen prophecies in a book and set it on a lectern with a comparator. A long line of lamps shows the power of each page, and a hidden vault opens only when full power reaches the very end. Find the magic page and hide your treasure.
Finish line: Your power bar shows every page's strength, and the Oracle's vault opens on the last page only.
Bonus challenge: Move the vault piston to block 12. Predict which pages open it now, then test. Can you make a vault that opens on pages 12 to 15 but not 1 to 11?
You’ll need
- Book and Quill
- Lectern
- Comparator
- Redstone lamps
- Redstone dust
- Sticky piston door
You choose
- The Oracle's name
- The vault's treasure
- My bet: lamps lit on page 8
Stuck?
- Lamp count off? The book needs exactly 15 pages for each page to match its number.
- Vault opening early? The piston door must touch only the last block in the line.
- Keep other wiring away from the lectern, or it can mix with the comparator's signal.
