Ager's Scepter - Exotic Trace Rifle - note: this exotic quest can soft lock if you pick up an Atlas Skew without the relevant quest step. Make sure your Tracing the Stars or Hollow Coronation quest lists a Skew as a current objective before you collect it. You may need to revisit the seasonal vendor in the H.E.L.M. to pick up new quest steps.
In Year 4 of Destiny, content will be available on an annual cycle rather than a seasonal cycle. As seasons end, seasonal activities and quests will remain available as Legacy content, a departure from Year 3's norm. Guides from the above section will be moved to this one as seasons end to ensure those resources are still available as long as the content they reference is.
Dead Man's Tale - Exotic Scout Rifle (random rolls of Dead Man's Tale are farmable through the Presage mission)
Presage - The Presage secret mission initially awards the Dead Man's Tale exotic weapon and the Master difficulty variant rewards the catalyst through a quest from Zavala. Datto's Dead Man's Tale quest guide doubles as a basic guide for this mission.
Datto's “comprehensive” Dreaming City guide - Note: this guide was prepared before the Dreaming City was cursed. Where it contains incomplete information on Dreaming City activities, please consult the guides listed below.
Note: this acquisition method is only available for players that own the Forsaken expansion. Players that do not will be able to acquire the weapon through a quest from Shaw Han, the Cosmodrome vendor.
Note: this guide references the Ascendant Primeval's spawn rate being related to the Dreaming City curse's strength. This feature has since been patched, the Ascendant Primeval's spawn rate is now static at all times.
