History of The Prophet

Overview

The Prophet is a Legendary weapon: Scout Rifle (Aggressive Frame), Stasis, 120 RPM, 13-round magazine.

Curated roll per the fan wiki: Fluted Barrel, Flared Magwell, Subsistence, Killing Tally; Tex Mechanica foundry. Introduced in Season 23.

Acquisition

The fan wiki lists Trials of Osiris challenges via Saint-14 (Season 23). Bungie's item text says to "complete Trials tickets and earn rank-up packages from the Emissary of the Nine", which is the Trials rank-up reward track. Older and newer sources describe this differently, so check in game for the current rotation.

This is a legacy-style reward weapon. It is not a craftable or Adept weapon as far as the sources show, and sunset status was not stated by the sources I opened (the fan wiki is the main source). See also Saint-14 and the Crucible for the PvP context.
