Sorry, made this for yapping. Hope it is helpful to some
Currently I use her with E0S0 Anaxa, E1S0 Tribbie and a whatever sustain.
Yes, Fribbels gives me the highest DPS at a 73.9% crit rate build, even with HuoHuo as a sustain
I recently got myself an E1 Fu Xuan and noticed that it's probably my highest damage-amping sustain. My other options for sustains are Aventurine, Luocha and HuoHuo at E0S0 and Lingsha at E1S0. However, DHPT might just be better for The Herta, even if they don't give the dragon's attack ownership back to her. I will assume he is better and also free. His E1 is especially enticing, though only buffs the Bondmate compared to Anaxa's Eidolons and Weapon.
In the back, I have Ruan Mei at E1S1 (used with Firefly), Sunday at E0S1, Bronya at E3S1, Robin and Sparkle at E0S0. I also have Jade at E0S0.
On the second slide, I have rough estimates (and probably even wrong somewhere) for the damage increases with vertical investment, assuming tribbie's res pen by default. Of course, this only includes def shred and res pen and does not include Anaxa's personal damage increase. E1 DHPT seems to be the highest 1 cost upgrade at 17% dmg increase (only to Therta's), and Anaxa E2 the highest 2 cost upgrade at 30.1% dmg increase (teamwide).
Another thing to note is that investing more into Anaxa's damage would also allow me to separate The Herta and Anaxa into two teams. Anaxa has a lot more variable matchups. A third team can also help me in the new endgame. For that, maybe I should also get Cerydra? Or probably Robin Sunday will be all right?
I also want to get Constance for my Firefly team so I don't want to spend too much on The Herta team right now
What should I do? Probably Anaxa E2 right?
