osseous fragments destiny 2

In Destiny 2, "Osseous Fragments" are a material tied to the Season of the Haunted (Season 17) and the Derelict Leviathan activities. Here's what you need to know: How to Obtain Osseous Fragments: Nightmare Containment (Public Event) Completing tiers of this event on the Derelict Leviathan (Moon's patrol space) can reward Osseous Fragments. Sever Missions Completing weekly Sever missions (accessible after progressing the seasonal story) grants them. Opening Chests Some chests on the Derelict Leviathan, especially those requiring Opulent Keys, may drop them. Seasonal Challenges Some challenges in Season 17 rewarded Osseous Fragments. Uses for Osseous Fragments: Used to focus Umbral Engrams at the Crown of Sorrow (H.E.L.M.) for specific Haunted weapons and armor. Required for upgrading the Crown of Sorrow vendor upgrades (if you played during Season 17). Current Status (2024): Since Season of the Haunted is no longer active, Osseous Fragments cannot be earned unless Bungie reintroduces the Leviathan or its activities. They also have no use now, as the Crown of Sorrow focus system is deprecated. If you're looking for similar materials in current seasons, check for Phantasmal Fragments (Moon) or newer seasonal currencies like Herealways Pieces (Season of the Wish).
