When a player is playing UB and is facing another UB in the opposing team and they use the life leach skill that stuns on each other "at the same time", they both get stuned for the durantion of the skill and after that both players get stuck, can't attack or use skills.
They can still use warpstone or teleport scroll but that wont unstuck them, only death unstucks the demigods.
A nice way to test this is if both UBs are out of the skill range from each other and use the skill on each other. Both UBs will move to the other and when they get inrange they get stunned and get stuck.
