Answering most of the questions on this sub in one post + video demonstration
​
E2 Phainon > everything else, first and foremost. If you want to keep playing him long-term, that’s the first thing you should get. And yes, E2 Phainon still zero-cycles every mode except AS.
Yes, you need Cerydra. She’s the BiS support because she provides a unique mechanic. Yes, she has some anti-synergy, but that’s normal Hoyo practice for strong characters. Fugue and Firefly are a perfect example of this.
Yes, Cyrene is the second BiS. Yes, even at E0.
E2 Cyrene is the best third investment after E2 Phainon and Cerydra. It changes the game so much that with E2 Phainon + E0 Cerydra + E2 Cyrene, you can clear all three Arbitration Knights with 3 stars. And honestly, E2 Cyrene is the best support in the game for any character. I even use her with Seele for Arbitration zero-cycles.
Yes, Sparkle is better than Sunday. By a lot. E2DDD Sparkle > E6S1 Sunday
Yes, Bronya is also better than Sunday. One stack literally means nothing.
DDD, Vonwacq, and 160+ SPD supports are the best investments outside of pulling.
The fourth slot. E1 Tribbie ≈ E2 Sparkle. One is for AoE content, the other is for ST and blast content.
E1 Blade also works as the 4th slot, BUT only if you have E2 Cyrene.
Yes. Pull Cyrene, especially if you have more than one Amphoreus DPS.
No, don’t pull Sunday or his eidolons just for Phainon. If some useful novaflame appears later, you’ll be able to deal with it then. Pulling for a possible future is a VERY bad idea.
I think I answered most of the questions. You can be as mad about it as you want, but I’m talking about what’s best for Phainon. That’s all.
P.S. Yes, eagle set. The answer is always eagle set.
P.S. 2 No, the video isn’t mine.
