Perdition Flawless Solo Mastery

Overview

Perdition Flawless Solo Mastery is a Europa Triumph in World, Exploration, worth 5 triumph score. Complete Perdition on Master difficulty with no other players in the fireteam, and without dying.

How to complete

1. Travel to Cadmus Ridge on Europa and launch the higher-difficulty Perdition version when it is available. Select Master; a normal patrol clear is a different activity version.
2. Prepare Barrier and Overload counters. Fight the opening Hydra and Harpies from cover, then progress into the Minotaur room.
3. Clear the route before climbing the spiral stairs. Keep the Wyverns at range and deal with the Barrier Hobgoblins before pushing toward the boss.
4. Defeat Alkestis, Sacrificial Mind and collect the sector's completion chest while remaining solo.

For the flawless condition, retreat to earlier cover when pressured and recover before the next wave. If you die, restart the sector for a fresh attempt. A deathless Master solo clear also fulfils Perdition Solo Mastery.
