Among the endgame activities available via Destiny 2: Curse of Osiris, the mysterious Lost Prophecies feel closest to the grinding involved during Destiny in year one. The Prophecies are a series of ‘quests’ that grant 11 unique Legendary weapons, each one requiring specific materials to unlock. These materials are acquired by opening loot chests, completing Strikes of all difficulty levels, and upon completing regular Crucible or Trials of the Nine matches.
Owing to dependency on RNG drop rates, the materials can take hours to accumulate, but they drop on any region – not just Mercury. If you are routinely playing the breadth of endgame activities in Destiny 2, all 11 specially forged weapons shall be yours eventually.
How to unlock Lost Prophecies
First, you’ll need to complete the main story missions: The Gateway, A Deadly Trial, Beyond Infinity, Deep Storage, Tree of Possibilities, Hijacked, A Garden World, and Omega. Next, Mercury vendor Brother Vance lays three new Adventures before you: The Up and Up, The Runner, and Bug in the System. Finally, you have the choice of completing any one of these three Adventures on Heroic difficulty. Succeed and Brother Vance bestows Lost Prophecies, Verse 1 upon you. After this, there is a choice of running order, roughly mirroring difficulty. Verses 1-10 are all grind-oriented across activities, only Verse 11 provides a short quest.
Where to find materials for Lost Prophecies
Brother Vance requires three material types in varying quantities, which he will upgrade to the necessary components used in the Lighthouse Forge specific to each Legendary weapon.
One Concentrated Radiolarian Culture is equal to 10 Radiolarian Culture samples that are routinely gained from public events and all types of loot chests littered across the planets.
One Advanced Paradox Amplifier is equal to 10 Paradox Amplifiers, randomly awarded after all Strikes including Standard, Heroic and Nightfall. Also, for completing all Crucible matches and conquering Heroic Adventures on Mercury.
Fossilized Hermaion Blossom is the hardest material to come by, in terms of difficulty and time consumed. It is a rare drop from Heroic Strikes, Nightfall strikes and Trials of the Nine. Only five weapons require Fossilized Hermaion Blossom to forge, with 10 needed in total.
Bear in mind that since both Fossilized Hermaion Blossom and Paradox Amplifiers drop from Heroic Strikes, these are the most time-effective endgame destination for Lost Prophecies.
