Vault: Well of radience, whatever wave frame you like most (works wonders against Phalanxes) and a heavy weapon that does not cause selfowns. Caiatl: Forerunner (amazing against bellkeepers and snipers in dmg-phase), Glaive of choice, A heavy that doesn't cause selfowns (I used Lament, also to negate being thrown off the map if required) Karnstein's (work with glaive)

I haven’t used my Warlock to solo flawless a dungeon since Pit, which was a long while ago. What I can tell you is that the Assassin’s Cowl Arc Hunter build made a lot of my solo flawless Duality run a breeze. I used Lament for all three encounters and if you’re running a Well that’s still a great option heavy wise. You can run double special for the entirety of the dungeon if you want but I personally like having a primary option. Succession is great for shooting bells. Forbearance is top notch for clearing adds during the Vault encounter. Cartesian Coordinate is solid for dealing with Bellkeepers but any weapon that deletes them and their backpacks will suffice. Honestly you can get through this dungeon without doing too much loadout swapping. Especially if you’re going to disrespect Ghalran lol.
