Either this is very poorly documented/guided in-game, or mine is broken? I've searched forums, reddit, etc. and not seeing anyone else with this issue. Maybe I'm just blind to something the game is trying to tell me? I'm Season Level 20, Power level 1012 and grinding. Decrypted dozens of Umbral Engrams, but I've never been able to actually do anything with the Prismatic Recaster. I kept thinking maybe I'd get to some point with Power or with Campaign and it would unlock naturally via Story, but all that has changed is that it now presents me with "Rewards" , but they are all inactive because my Umbral Research Level is 0. Lots of searches, YouTube vids and guides later, it seems like all I should have to do is walk up to it and start turning in my Twisted Energy and/or Altered Element - I have 500 of one, 850 of the other. This seems like it would make sense, since that's what you do with planetary resources at each planet vendor for legendary engrams. However, I have no interface to turn in my Twisted Energy or Altered Element at the Prismatic Recaster. Drifter has nothing else for me - I don't see any quests in my logs that relate to this content - I'm done with all Campaign activities - it's just grinding Bounties now. So I'm not really sure what else to do with this. I have 7 Umbral Engrams in my Inventory just waiting to try out this Recaster, but it seems I'm stuck unable to level it and use it. Any ideas or help would be greatly appreciated!
