I tried many CoC skills this league to have fun, Flicker was one of them, but sometimes too random and got one shoted, with Cyclone you still die, but less often and have a higher trigger rate without depending on awakened multistrike. This build involves lots of chain + chain range + 12+ tendrils of exsanguinate + HoI + HoA + 60% chance to explode. I would say a flicker CoC + EK (which I had) is faster, but less reliable as you die pretty often and have less damage.
I tried ST as a trigger skill, was very good surprisingly, because you throw them and then they trigger when they get back to you as you just breeze through, triggering your spells (in this case was EK).
LMK if you have any questions!
