So I loaded up Rumble, Pulled the Matchmaker and waited for Banygan To queue up. I noticed that I had the Charge Stone Equipped. I changed it via the Wall of Stones to the Volatile Stone. About 10-15 seconds later we match together.
Midway through fighting, we realized I have the Charge Stone on his visuals and Volatile on mine. Including effects and sounds separate for each side. (I saw Volatile effects I could create and He saw(effect)/heard(ding) my charge building)
Charge Stone was the active effect stone though.
I have player.log saved if needed.
