Dangerous Waters Mod FAQ
10 questions players actually ask, answered.
How do I start exploring underwater in dangerous waters?
Craft a 
Teranium Diving Helmet first—you'll need 
Teranium Ore found on the ocean floor. Stock Teranium batteries in your inventory and equip the helmet to breathe underwater; the on-screen battery tracker shows your oxygen supply.

Teranium Ore spawns on the seabed across most ocean biomes, with higher concentrations in Rocky Ocean and 
Heat Mushroom Field biomes. Mine it with a stone pickaxe or better.What's the best underwater armor set?
Crystal Teranium Armor is the full upgrade—it increases swim speed, boosts block reach, and grants random oxygen bursts underwater. Pair it with Water Jet Boots for maximum speed across deep trenches.
Do I need the 
aqua jet vehicle to explore?
No, the Aqua Jet is optional and speeds up travel across open water, but you can explore all structures and biomes by swimming with proper armor and oxygen gear. Keep a repair station nearby if you do use it.

Dark Rock Field is the most peaceful—it's made of 
dark stone boulders with very few hostile mobs, making it ideal for gathering resources and learning the mod before tackling dangerous zones like Void Forest or Forgotten Plateau.

Dragon Sharks, Devourers, and Sand Stingers are highly aggressive and deal heavy damage; avoid Void Forest and Forgotten Plateau until you have full Crystal Teranium Armor. Ghost Worms and Electribbons are also dangerous in groups.
How do teranium batteries work?
Batteries are consumed from your inventory while wearing a Teranium Diving Helmet to extend your underwater oxygen supply. Craft or find enough batteries before long expeditions, as running out leaves you vulnerable to drowning.

Breaking wood piles scattered across the ocean floor yields sticks, logs, gold nuggets, and other items—they're a reliable early-game resource source before you can mine Teranium.
Can I build underwater bases with this mod?
Yes, the mod adds over 50 decorative blocks including stairs, slabs, and stone variants specifically for building. Teranium blocks and other ocean-themed materials let you construct bases that match the underwater aesthetic.
Does dangerous waters affect performance or cause lag?
With 50+ structures and 15+ mobs generating across oceans, performance depends on your system and render distance; consider lowering chunk render distance or structure spawn rates if you experience lag in ocean areas.
