Why does Kled gain hp after he loses his pet?
As Darius, I depend on the fight lasting 5 stacks so I can just ult and win. I get him off his pet and ult and it doesn't kill him as if he had a few less stacks than max, and everytime I ulted after he was off his pet, he survived every time by a nominal amount. I don't understand what this interaction is, but it's pretty stupid cause I couldn't get the kill (and Kled also thrives on extended fights, so it's not like I can spare his whittling him more for the time being).
Darius is strong in average ELO, I know, Kled's not an issue, I'm not asking for nerfs, but why is it that my ult was never able to finish him after he was off his pet with 5 stacks?
