Solo Expert Lost Sectors
Complete Expert Lost Sectors solo.
Each day, one Lost Sector is available to play on Expert difficulty. Completing it solo grants an opportunity for much rarer rewards, at a greatly increased combat difficulty.
You must complete the normal version of a Lost Sector to unlock the Expert version.
The most recent Exotic armor pieces can only be acquired through completing Expert Lost Sectors solo.

Overview
Solo Expert Lost Sectors is an introductory progression record for five solo Expert Lost Sector completions.
How to complete
First clear a sector's normal version to unlock its higher-difficulty version, then launch Expert with no teammates. Prepare the required Champion counters, defeat the sector's boss, and open its reward chest to finish the run.
Repeat qualifying clears until five completions are recorded. The objective permits repeated completions rather than requiring five different sectors. Remain alone throughout each Expert run; normal patrol clears do not replace the stated difficulty. The record does not specify flawless completion, so the completion counter is separate from a sector's solo flawless achievement.
Objectives
- Lost Sectors (0/5)
