Upgrade Your Swimming and Combat Abilities

Craft Water Jet Boots

Gather Teranium ingots and craft Water Jet Boots at your crafting table. Equip them to significantly increase your swimming speed, making traversal across deep ocean trenches and between structures much faster.

Assemble Crystal Teranium Armor

Collect Teranium ingots and Blue Crystals (found in the Forgotten Plateau biome) to craft the full Crystal Teranium Armor set. This armor provides multiple benefits: increased swim speed stacks with your boots, extended block reach for mining and interaction, and random bursts of oxygen that activate while underwater.

Combine Armor and Helmet

Wear your Crystal Teranium Armor alongside the Teranium Diving Helmet for maximum underwater capability. The oxygen bursts from the armor complement the helmet's battery-powered breathing system, giving you redundant survival tools.

Test in Dangerous Biomes

With full upgraded gear, you can safely explore more hostile areas like the Void Forest and Heat Mushroom Field. The extra reach helps you mine resources from a safer distance, and the speed boost lets you escape threats quickly.
