You mean on Eula? She doesn’t need (and should never use) ER sands, as far as I know.

Remember, we’re talking about mains here. People who have been farming for her for ages, even if just on and off.

I use ATK sands, and my Eula can self-fund her burst off cooldown 100% of the time, not even needing Diona. I use another Cryo unit mostly to guarantee the extra Crit from the resonance in the ult’s hit specifically (since Eula always applies cryo again a few miliseconds before the ult hits, with her final Hold E). But I already have 70% Crit rare, so I could honestly go without it.

Eula doesn’t have energy problems with a good build. And she doesn’t exactly need more damage — except perhaps on her auto attacks, but then Raiden doesn’t help with that, she actually is a damage down for that compared to C6 Fischl. I think.

Anyway, we’ll have to wait and see. My point is that at least based on what I’ve seen so far, Eula’s kit doesn’t actually need anything Raiden provides. It’s useful specially if you’re a beginner, but if you already have her built, Eula can be fine by herself, and equal or probably better with C6 Fischl.

Eula’s issues are NOT burst damage or ER at all. Her burst is already a more than sufficient nuke and you can’t kill enemies any more dead, and her ER completely fine at 135 with a battery, and at 170 without one.

Eula’s issues are - Her burst missing disastrously because enemies dodged, disappeared, jumped, have shields, moved out of the way, dash attacked out of her area, etc which almost every enemy does so attention is extremely necessary. - Her auto attacks being extremely weak COMPARED to Hu Tao’s dashes, Ganyu’s bloom, Klee’s chargeds, or pretty much any other team. Meaning her damage is loaded towards the end almost entirely, so although she deals the same amount of damage or more over time, at the beginning she is 50% weaker than anyone else who does the same damage, just because of how the damage is distributed.

Leading to the quirk that against weak enemies she is 50% weaker because she’ll kill them slower with her autos first, then the burst is either wasted or not used —while almost any other character would have killed them 50% faster because their damage is evenly distributed. It all equalizes when the enemy has enough HP, and it’s not as bad as it sounds, and she is still capable of doing Abyss, of course.

I’m just pointing out that her issues are not ER and Burst Damage, but rather those two little quirks I mentioned, which Baal does literally nothing to address, actually just taking away a bit of DPS because C6 Fischl seems to be stronger.

I still hope that Raiden buffing Beidou will make her better than Fisch………… but at that point, since I don’t need cryo resonance, Bennet would just be better anyway, better buff for Beidou, best healer, and although he doesn’t synergies with Eula the best, neither does Raiden so if Beidou buffing is the only reason then Bender ends up better.

MAYBE. I don’t know how it’ll actually be. I await anxiously the test results. Maybe she’ll be a clear upgrade still :) we’ll see.
