"Immortal Enemies" lol I'm not surprised they should be Titans
Did you realize that you have three "For Each" in arrow and in a sub-events? and that you don't need any of them
Plus the trigger once in event 43 is making you a big mess there combined with the Waits
Remove all the "For Each" three of them
Set event 41 as the top event
--SubEvent: Kopatropa Health = 1 >>>> your Actions
--Else Health <= 0 >>>>>>>>>your Actions
Also, I would remove all the waits, replace them with Timers
try and see how it goes
