Pain Keeper sometimes skips her turn in arena when going first
I can't find a way to manually skip a turn in arena. Pretty sure it is not possible. I have Pain Keeper on one of my 3v3 teams. Her speed is 218 and she is the fastest on this team. I'm in Bronze 1 in 3v3. I am only talking about when I go first in battles. If it is a significantly lower team like 4 lvl 30s and 40s or 1 low champion she will go first and use her A2. If it is a harder team, she will "skip" her turn and Deacon ((speed 207 in video) or whoever else I put in the team) will go first. I've watched this with different teams. Don't matter who I put in this happens. I don't mind it. I can win 20 battles a day in B1. I just do not think it is intended. These two video's were recorded one after another on two different battles. No changes were made.

If you need more evidence, like complete video from fight to fight, I can do it. Just didn't want to make a long video with all the battles in there.
