3rd secret chest encore destiny 2

It looks like you're referring to the "3rd Secret Chest" in the Encore mission of Destiny 2's "The Whisper" (or possibly another secret mission). Here's what you need to know: Possible Interpretations: "The Whisper" (Io) / "The Whisper (Heroic)" Secret Chests - There are 5 hidden chests in "The Whisper" mission (3 in Normal, 2 extra in Heroic). - The 3rd chest is located in the "Green Room" (the large open area with Taken blight orbs). - After jumping down into the Green Room, look for a hidden ledge on the left side (near a tree root). - The chest is tucked away in a small alcove. "Zero Hour" (Encore Variant?) - If you mean "Zero Hour" (the Outbreak Perfected mission), there are also hidden chests. - The 3rd chest might refer to one in the Ventilation Maze or Trevor's Lair. "Presage" (Glykon) or "Vox Obscura" - Some secret missions have multiple chests, but "3rd chest" isn't a common reference. How to Get the 3rd Chest in "The Whisper": Enter the Green Room (after the jumping puzzle). Look left as you descendtheres a hidden ledge with a small cave. Jump to itthe chest is inside. Rewards: Blightsong Shell (Ghost Shell) If you open all 5 chests in Heroic. Catalyst Progress (Whisper of the Worm). If you meant a different mission, let me know! I can help clarify. Would you like a video guide for the exact location?
