Here is the video when our team beat the crazy Yeti King. It took 4 rounds, I just show the last 2 rounds.
The first two round was standard, drain half of his life. We didn't guide the imp closer to Yeti king on the 3rd round causing the 3rd round attack less efficient.
Luckily the final round, the Yeti King is very close so drained almost 1/3 of his life.

I'm doing the bodyguard role and while cleaning the incoming zombie, my meter got full and release my chuck shot. Imagine if you're using Iron Citron, it will be a blast.
The last round, we push really hard, barely made it, the clock end at 0 seconds when the final chuck shot finishes it off.
