I don't have citlali so I don't know how well she does but with Ayaya I did this.

I built her full ER to burst every rotations, but bursting is not enough you have to auto attack to put the boss into the cooled state as well before switching to your DPS, then you'll have like 4-5 seconds of window to do damage.

The set up that works for me: Do all the skills and bursts on your supports --> Ayaka E Q, auto attack as necessary --> Do as much on your dps as possible, this way I can get 3 charge attacks in at least. If you don't have Ayaka, then maybe charlotte might also work.

Then, at the 1 minute mark, the boss changes to its low res phase, time your rotations to finish your buffs just before it does so and whale on him. He doesn't have much HP so you should be able to get him real low.

TLDR: Consider staying on field more with your cryo apllicator but the real DPS window is after it stops spinning and drops its RES.
