There's been a few posts from folks having issues starting the "Legacy: Challenger's Proving" main quest chain from Season of the Chosen and "Decrypting the Darkness". Here's a few pointers to help. [b]Note, you MUST have purchased the Season of the Chosen or the season pass in order to start it.[/b] Starting "Decrypting the Darkness": If you do not have a prompt for this quest at the Prismatic Recaster and/or the War Table and cannot access Umbral Focusing for the previous or the active season (if you can access umbral focusing, you've already done it), go to Nessus and run the Battleground to the northwest of The Tangle. After running the battleground, make sure you have an Umbral Engram. If you do not have one, run activities until you do. Visit the H.E.L.M. and you should be able to pickup the quest from either the recaster or the focuser. Decrypt an umbral engram AFTER picking up the quest to complete it. Starting "Legacy: Challenger's Proving" quest: If you have a prompt for the War Table but cannot interact with it (says "Legacy: Challenger's Proving" and to meet Osiris and the Crow at the War Table if you hover over it, but they are not there), jump on the table about halfway down, face the front circle, and move forward. At some point, you'll get an "Interact" prompt (Bungie, please fix the proximity of the interact). Approximate location in screenshot here: [url]https://imgur.com/a/hdhClko[/url]
