Also anybody that actually survives gets the damage they took amped by 67%. If a hero with 1000HP gets hit with this ult and is left with 200/600, it becomes 333/1000 after the debuff wears off, meaning 400 damage became 667 damage. 550 damage would normally take him just below half health, but now it's suddenly 917 damage, hitting him for over 90% of his health.
Ridiculous. Put a Portal Key on this guy and it's GG.
