JKL Heroes Arise , Cooldown Manipulation

Some additional info--rereading JKCK's kit, his second attack is actually a bonus turn, so the count going down by 2 after him during a non-Leia battle is WAI.

For the Leia battles, it seems like it is adding an extra cooldown reduction and that this effect stacks per turn. It is hard to track an exact pattern because it reaches availability so quickly. However, I've noticed that it's not always consistent. It usually goes from 9->7 in the first stack, but you have an instance of 9->6 in your video. Sometimes the next stack is 7->4, and other times 7->3.

I've tested without JKCK as well to see if it was his unique interacting with Leia. It seems very much just to be an interaction between Luke lead and Leia.

I wonder if the code for immunity to cooldown manipulation overrides and then reinstates the standard turn end cooldown? That might explaining a double cooldown reduction, but not necessarily the stacking effect.
