Aether Sea

Description
Aether Sea planets (typically identified by your ship computer's description of them as having a "strange sea") are among the deadliest found in Frackin' Universe, with Hazard Levels ranging from VI-VIII. They most frequently orbit Blue, Black, and Binary Stars. Aether Sea planets are characterized by an abundance of liquid Aether, with small islands interspersed throughout. All of the Tier 6 vanilla ores (Solarium, Ferozium, Aegisalt, and Violium) are plentiful on Aether Sea planets; they usually include moderate quantities of high-level Frackin' Universe ores, as well, including Corruption, Uranium Ore, Neptunium, Thorium Ore, and Penumbrite Ore. Aether Sea planets are also the only naturally occurring sources of Xithricite ore.

Exploration
Acid Protection (either through Whitespine, an Acid Shield EPP, or various armor sets) is a requirement for exploring an Aether Sea planet, but the real environmental threat is the liquid Aether itself, which applies the Shadow Tainted debuff when touched. Shadow Tainted reduces visibility to near-zero, which makes responding to enemy threats or finding the valuable ores on the sea floor almost impossible. Pyreite Armor is the best early choice for exploring these planets, although Xithricite Armor also provides immunity to Shadow Tainted. For very late-game players, the Shoggoth Armor acquired from the Frozen Wastes features immunity to the Shadow Tainted debuff.
