Hello!
I just asked myself what happens when I use felflame on a dot thats buffed by something. For example a UA that was applied with the 1600int procc from Volcano-deck and when the procc runs out I extend it with felflame. Does the FF extend the buffed UA? Is the entire UA recalculated when the Felflame hits? Or are maybe only the seconds that felfame adds calculated without the buff? Help is appreciated!
