Survival Tips by Biome

  • Shallows: Safe. Farm resources freely.
  • Jelly Barrens: Stay near the seabed. Hammerheads roam mid-water.
  • Old Habitat: Approach carefully. Check for Deepwing before entering buildings.
  • Hydrothermal Vents: Bring medkits if you don't have Heat Tolerance. Get in and out.
  • The Hole: Hug the walls. The Great Jaw patrols the center.
  • Karakorum: Always have a fully charged Tadpole. Carry a Repair Tool. Save before entering the trench.
