How to Escape the Deeper Dark Dimension
Searching the Dimension for an Ancient City
Getting out of the Deeper Dark requires active exploration, as you must locate another Ancient City generated inside the Deeper Dark itself to leave. Because the dimension is covered in sculk and the Warden is the only mob capable of spawning here, noise is your sole threat. Stay crouched as you travel, use wool blocks to muffle your footsteps when bridging across gaps, and keep your distance from Sculk Sensors so you do not summon a Warden while searching for an exit.
Using the Return Portal
Explore the subterranean terrain until you spot the familiar deepslate architecture of an Ancient City. Before heading to the center, check your inventory to confirm you have an Echo Shard ready. If you do not have one on you, quietly surround nearby city chests with wool and loot them until you find a replacement Echo Shard. Once ready, sneak up to the portal in the middle of this Deeper Dark Ancient City, hold the Echo Shard in your hand, and walk through the portal to escape.
