Concealed Void Solo Mastery

Overview

A 5-point triumph: complete Concealed Void on Master difficulty without a fireteam.

Concealed Void is a Lost Sector in Rathmore Chaos on Europa, under the Asterion Abyss north of Charon's Crossing. The boss is Teliks, House Salvation, a Fallen Captain with reinforcements, and a chest drops at the end.

How to complete

Master modifiers: Solar burn, Solar and Void shields, Barrier and Overload Champions, radar disabled (Chaff), and more enemy grenades; equipment is locked, so choose your loadout first. Power requirements vary by season.\n1. Entrance is the hardest part: kill the Dregs first, then the Overload Captain, then the Barrier Servitor.\n2. Radiolaria pool: clear red-bar enemies before Champions; removing about 25% of the Servitor health forces its barrier to deploy.\n3. Corridor: jump back right after crossing to dodge the Explosive Shank blast, then take the Champion pair.\n4. Boss arena has no Champions: burst the Captain with Heavy ammo through three health phases while handling Servitors and adds.\n5. Bring long-range weapons (Scout Rifle) plus a Barrier-breaker and Overload stun (Xenophage and Polaris Lance were suggested). Voidwalker for Devour, Sunbreaker, or Gunslinger were suggested per class.
