Man, it's gonna be a long time to get Kusanali up to 9/9/9 talents. I'm sitting at 6/7/6 currently waiting for my friend to do weekly bosses on the weekend like usual. Decided to stick with Sacrificial Fragments on her for now. I actually find myself using the tap version of her skill more than I expected to, to just mark nearby targets without worrying about aiming. The bonus cast has been nice when I miss marking one or they die so quickly that others spawn before the cooldown would normally be up.
C2 Kusanali + my C6 Keq has been so insanely fun. If you'd have told people at launch that Keq would regularly hit 20k normals, they'd laugh at you. I actually brought Sara out of retirement for that team too, since her buff is actually pretty great for Keq's Burst. I'm able to take a Dendro cube down from 100% to 1% in a single burst + use of skill + a few swings. This team makes farming Sumeru talent books a breeze too.
Unfortunately, Kusanali doesn't pair well with Cyno. He does so much damage so quickly that the 1st wave of enemies is gone, then you either have to continue with no Dendro application or swap him out and lose his burst which takes forever to charge. I'll stick with Collei for him, for now, as she provides the best extended duration of Dendro that we have available, and her burst is always ready with its low energy cost.
After my Cyno hits rank 10 friendship in a few days, I'm going to do a Nilou meme team for my daily comissions/friendship farming team, just to see how it works with Kusanali. It has to be better than with Dendro Traveler or Collei.
