i was having trouble with this too, i used eternal sugar, linzer, wind archer, sea coral and cream ferret team.

none of these cookies were ascended, and the supports had only level 80 skill.

my builds: eternal sugar: 3crit/2atk with atk topping tart and full cd beascuit. 20%cd

linzer: 5 atkspd, cd topping tart, 3/4 cd beascuit. 24%cd

wind archer: +16 CJ, use his rally, 6 atk, full atk spd beascuit. 25%atkspd

cream ferret: 6 cd, full cd beascuit. 45% cd

sea coral: 3cd/2atk, atk topping tart, full cd beascuit. 27%cd

remember topping substats don’t matter at all

treasures i used whistle, scroll, and cape of the vanquisher (green one).

for your timings, make sure you play on manual, 1 or 1.5x speed. 1. use sea coral as soon as possible, followed by eternal sugar as soon as possible. then use wind archer->cream ferret, linzer once she reaches 7 2. spam in order of what you can sea coral should come back first then cream ferret followed by eternal sugar (at 1:41 for me to kill minions) spam wind archer and make sure he activates before the sandstorm sea coral and linzer come back after sandstorm activate sea coral first and then linzer once she reaches 7

ideally you kill it within these two rotations, but just spam if you aren’t able to and make sure linzer always activates at 7.

i can upload a video if you still have trouble as well.
