A buff for Darius: his ult refreshes on kill but can't be used on the same target for 120/100/80 sec
Basically, it would be what live Darius is but if he kills his laner with his ult, he will have it up but HE CANNOT USE IT ON HIS LANER WHEN HES BACK IN LANE UNTIL THE COOLDOWN IS OVER ON THEM. Not the 20 second extension.
This would be a huge buff for top Darius with teleport and jungle Darius as they can safely secure kills with his ult and still have it against other targets.
Think of Yasuo's E, you can't dash on the same guy for 10 seconds, that's how this ult would work.
Cdr would reduce the frame in which you can ult the person again.
Edit: Fixed first sentence
Edit 2: Clarity purposes heres how it goes.
You dunk your laner and secure the kill, your ults cooldown is refreshed. 40 seconds later in lane again you get in a fight with your laner and the enemy jungler, you can use the ult on the jungler but NOT on the laner. In order to show this for both sides there would be a debuff on the enemy he has recently killed with his ultimate that won't let him cast it on them until the cooldown is over.

over him any day. And technically, even
thanks to his W and his passive.
