Dive to your underwater base, upgrade it and seal a seafloor time capsule.
Under the sea, past the dome you built long ago, there's room for one last secret. Seal it where no one looks.
- New skill Building a sealed underwater vault
- Level 10 · Legends of Lilora
- Difficulty Advanced
- Mode Survival
- Time 45–60 min
- Ages 13+
What you’ll build
Dive down to your underwater base, note what needs an upgrade and write a letter to your future self. Brighten the base and add a memory wall, then dig a prismarine-lined vault in the seafloor, seal your letter inside and note exactly where it's hidden.
Finish line: Your base glows brighter and your letter is sealed in a seafloor vault, its coordinates on a plaque inside.
Bonus challenge: Hide a second capsule with no marker at all. The only clue is a plaque inside the dome with its coordinates. Will future you find it?
You’ll need
- Water Breathing potions
- A turtle shell
- Prismarine
- A Book and Quill
- Sea lanterns
- Memory items
You choose
- What goes in the capsule
- Hiding spot: under the dome, in a trench or by the conduit
- My secret opening date (a mission number)
Stuck?
- Watch your air bubbles and surface before they run out.
- Water Breathing lasts much longer than a turtle shell's extra air, so drink a potion for long jobs.
- Torches won't stay in water. Use sea lanterns or glowstone to light the base.
