Using Underground Rivers for Fast Travel

Preparing Your Boat

Craft a boat before entering underground rivers. These waterways stretch across the map and connect different cave systems, making them the fastest way to traverse the underground.

Safe Boat Navigation

• Avoid poisonous water: Underground rivers are safe, but sewers contain toxic water that damages you
• Watch for drops: Rivers may flow into waterfalls or caverns—stay alert
• Bring supplies: Pack food and torches; you may be underwater for a long time
• Mark exits: Note where side passages branch off so you can return to specific biomes

Reaching Underground Seas

Following rivers downstream eventually leads to larger subterranean bodies of water. These underground seas connect multiple biome systems and serve as major hubs for navigation. Use them as waypoints when planning longer underground expeditions.
