How to unlock VERSE WEAPONS | Destiny 2 Curse of Osiris (Lost Prophecy Verse 1)
To unlock verse weapons in Destiny 2 Curse of Osiris, you have to first complete the story and all 3 mercury adventures. Brother Vance will now offer you 3 heroic versions of these adventures.
Complete one and collect the lost prophecy from Vance. But before you can use it and collect your Verse Weapon you need to activate it with multiple Radiolarian Cultures that you have to farm from public events and other chests on any planet.
Once you have all of them together, return to brother Vance once more and forge the verse weapon left to him.
