Got my first Penta kill today with Katarina.
How I did it was got fed a bunch and got my 20 stacks
They were all hiding under a turret like nubs and I was the only one there.
And I decided screw it what do I got to lose? Shunpo'ed in and ulti'ed
Figured out I killed them all GOT THE HELL OUT by shunpoing out.
It was pretty pro. They were pretty pissed.
