Alone in the Deep

Alone in the Deep is a triumph worth 25 points for completing every encounter of the Ghosts of the Deep dungeon solo. It is one of the triumphs required for the Ghoul seal.

Requirements

• Run the whole dungeon as one fireteam of one, never leaving the Ghosts of the Deep activity. Do not return to orbit between encounters, and nobody may join you before the final chest drops.
• You do not need to be flawless. Deaths do not fail it; only leaving or being joined does.

Tips

• The two bosses, Ecthar and Simmumah, are very tanky and take many damage phases. Bring high-damage weapons plus survivability.
• Solar Titan: Healing Grenades with Ember of Solace and Ember of Torches for constant Restoration and Radiant, Synthoceps for Throwing Hammer melee, Xenophage for burst, 100 Resilience for damage reduction. Tractor Cannon's Void suppression helps on Ecthar.
• Arc Hunter: Arcstrider with Assassin's Cowl, chaining Combination Blow melee kills for repeated invisibility. Riskrunner or Witherhoard for the Hive ritual, The Lament on Ecthar, Leviathan's Breath for Simmumah.
• Other options: Legend of Acrius on Ecthar, Arbalest to break Simmumah's shield, linear fusion rifles.

Rewards

Counts toward the Ghoul seal. Solo-clearing is also reported to raise the chance of the The Navigator Exotic trace rifle; reported odds vary by source.

Notes

Builds date from the original Season of the Deep launch, and later sandbox changes may alter them.
