Breathing Underwater with Teranium Diving Gear

Using the Teranium Diving Helmet

Standard air pockets and vanilla potions only last so long when exploring deep ocean trenches. Once you have mined Teranium Ore from the sea floor, check your recipe book to craft a Teranium Diving Helmet along with a supply of Teranium batteries.

1. Equip the Teranium Diving Helmet in your armor head slot.

2. Place your crafted Teranium batteries anywhere inside your inventory.

3. Watch for the on-screen battery tracker, which automatically appears on your screen whenever you wear the helmet while carrying batteries.

4. Dive underwater—the helmet draws from the batteries in your inventory to supply extended underwater oxygen. Keep spare batteries on hand during long trips and surface before the tracker runs out.

Upgrading to Crystal Teranium Armor

As you gather rarer materials from custom ocean zones and sunken structures, you can move beyond basic battery breathing by crafting a full set of Crystal Teranium Armor. Wearing every piece of this set at once grants three major underwater advantages: it boosts your swimming speed, increases your block reach for easier underwater mining and building, and periodically gives you random bursts of oxygen while submerged.
