I got Citlali at 84 pity, probably the highest pity I've ever had. Last one was 81 (C0 Neuv), at least it was a 50/50 won.
I wish my artifact didn't upgrade that much into DEF rather than ER, otherwise ER could have been better.
Here is damage comparison with her (Cinder) and Zhongli (ToTM), no Bennett buff. Just pure resistance shred between the two..
The lower number is Lyney's full charged arrow, the bigger one is his cat arrow damage.

It's 37k and 45k.


This one is scuff, best scenario for both. Citlali one is missing Lyney full charged arrow at 37k damage.
Zhongli case is keeping boss withing his pillar stone.
You are trading a kinda "meh" shield (worse than Layla, kinda similar or a tiny bit better to Kirara without stack) for higher possible damage But between Cinder and ToTM artifact, Cinder wins because you can swap Citlali to even spam normal attack to trigger elemental effect without requiring the e skill on hit (Zhongli pillar). Cinder buff is also last longer, 20 sec of damage buff vs 3 sec if ATK buff.
New world boss farm, you can use Citlali and Ororon (I assume) special vision to stun boss's clones.

I'd say, she's neat for me. Since she actually makes my Lyney team with Furina - Siggy being able to Tenebros boss Nightsoul shield and fighting against other mobs with Nightsoul shield much more easier.
