Managed to find another slideshow 83 degree setup
This screenshot was from before it got really bad. But basically some combination of when heal do x and when crit do x and spamming ability cooldown every upgrade made it so that every time I used my ability the next ability would go off slightly faster, infinitely.
I never found the "create poison cloud on explosion" perk. Because I had the "explode on poison cloud ending" and "2x Explosions" so that would have been an infinite loop on its own that would get twice as bad every cycle.
