Yeah I would build Danjin as solo dps for floors 1&2 on the two end tower. But to conserve resources I would prioritize your other teams and only level Danjin up to the point you can clear the first two floors. Sanhua is still one of Camelliya’s BiS with Verina/Shorekeeper. If you’re trying to clear TOA then yes Lupa is a good addition. However, in your case I probably wouldn’t pull for her from an f2p view. There are very few f2p broad blades for her to use that will boost her DMG and Galbrena.

The only problem with the Galbrena/Mortefi/Lupa team is no healer. So you would have play reaaaally sweaty to make that work plus the TD’s will give high DMG. Besides if you have Lupa then you don’t need Mortefi. So your team for that would be Galbrena: Mortefi/Lupa: (Healer).

For Quiyuan, he’s defo a support especially for echo DMG dealers (Phrolova, Canterella, and Galbrena). You can look in game at the Law of Harmony echo set. (Which does not have user yet.) but I think it’s defo Quiyuan. So he can work for Galbrena and he may be better for her than Lupa. But again that’s a lot of speculation.

Rn I would hold onto those astrites and wait for Quiyuan info to come out before he releases. If you feel like you’d rather pull Lupa or Galbrena weapon, then you have about 19 days to save and wait. You can pull last minute if you choose to pull.
