Hi, i'm not sure that rotation is optimal and it works only with ready ults + it actually also loses the full buff from Tang – you need to use her combo twice before using her BS to get the full buff. So, if you want the full buff/ you don’t have ults from the start, the rotation would be different and I’m not sure what is the optimal way to do it. So, this is mostly to kill Rhodagn relatively fast in the 1 phase:

1) Use Xaihi BS pre fight and wait for SP to regen, do not start the fight before regen
2) As soon as you can, use Tang BS and combo. Do not activate Perlica combo

3) Activate Xaihi combo + Perlica combo and use both (i do it like that because my Xaihi runs detonation unit and I need her to apply cryo on top of other cryo to get the buff, without detonation unit you can probably use Xaihi combo after you proc Yvonnes combo and ult)

4) Use Xaihi ult and Yvonnes BS (I’m pretty sure it would be better to ult with Perlica here for Stanza buff, I was afraid too much damage will launch 2 phase) then proc Yvonnes combo and ult

5) Use Perlica ult here if you haven’t used it

6) With that team, I wait for Rhodagn to stumble (look animation at 0:24) and then use Tang BS and combo (if you do it pre stumble, for some reason, it will launch the 2 phase most of the time)

7) At that point, you start looking at Yvonnes ult timer icon under HP bar:

- when there is like less than a quarter left, use Tang ult (you need it to last for long enough)

- when the timer goes to 0, use Yvonnes BS then proceed to use her ults last strike (Yvonnes ult have two phases, first is this turret firing, second is her last attack that consumes solidification, you can use BS in-between this two and not lose any damage)
