She was pretty fed, not gonna lie, but so was Olaf.
I still don't find a reason why she was able to take on 3 people and just drain tank them.
Items around that time: Riven: DD, Essence Reaver and Infinity + Conq, Bloodline
Olaf: Ionian Boots, Ravenous, RIghtous Glory, CInderhulk
Garen: Cleaver, Tabi, Jaurim Fist
Bard:well he kind of died before in even began, so it doesnt matter
