I have tried multiple times and matched 10-12 yellow gems (single match) each time. Rooster’s Crow never activates.
Can you share a screenshot of your Hero spell and passive loadout from the in-battle pause screen please?
I only used channel light in the first try and only used channel light + sunburst in the second try. I also tried it once with my warlock without casting any spells. Unfortunately, I am in season chapter 3 now and cannot provide any in-battle screen until elite mode is available.
Thanks for sharing these!
