Sagira's Shell

Overview

Sagira's Shell is an Exotic Ghost shell introduced in Curse of Osiris. It is earned by completing all of the Lost Prophecy verses on Mercury, and it carries Mercury-themed perks.

Earning it

Lost Prophecies are picked up from Brother Vance at the Lighthouse on Mercury, once the player has finished the Curse of Osiris campaign and the Mercury Adventures. Each verse is a weapon quest: collecting enough of its items completes the quest and yields a tablet that can be redeemed for a Legendary weapon from the forge. The verses are numbered, and the final one awards an Exotic shotgun, the Paradox. Completing all of them, including the Paradox shotgun quest, unlocks the shell.

Perks

• You're Welcome: Detects caches and resources within 75 meters on Mercury.
• Omni-Telemetry: Generates Gunsmith telemetry data when elemental weapon kills are made.
• Scion of Mercury: Increases Glimmer and the chance to get extra faction consumables on Mercury.

The verse list and reward details come from Curse of Osiris era sources (2017–2018), so availability may have changed in later seasons.
