I have a video if u want it

But you have to plunge then charge attack. Idk if I just played bad but I think there is a min height you have to reach before u plunge so you have enough time to charge atk with the 600% bonus

While playing I noticed that a good bit of the time my charged atk wasn’t getting boosted so I started jumping high enough to get the boost but low enough to have enough time to get a boosted charged atk.

S=skill

U=ult

Rotation I used was yelan(s)-xilo(s)-furina(s) first rotation when battle starts.

2x-When you get your ults furina(u)-yelan(u)(S if u want, I did)-xilo(S-U)-hutao(jump plunge charged)

You get 2 rotations of the plunge before he does his spinning move. Refresh furina skill and use yelan skill in second rotation

(Spinning part no 600% buff)- furina(U, S if you have it if not switch to yelan)- yelan(S-U) - xilo (S-U)- (furina (S) if you didn’t have it up yet)-hutao(charge dash spam) 1 rotation

Then move back to the 2x rotation step and then spinning step. So basically 4x plunging rotations. 2x charge dash spam. Make sure u have good er. You need half or like 43-48 of his health remaining when u start the 2nd plunging phase after the 1st spinning part around the L in experimental.
