First time Graves, PENTAKILL! Report

My first time ever playing Graves managed to land my first pentakill ever, I wish I could've recorded my reaction aswell (I sort of freaked out already at quadra) and when I saw penta I literally threw away my headset ran out into the hallway screaming ''PPPPPPPPEEEEENTAAAAKIIIIILLL''

That is the build which I used played another game right after where I got 15/2 so it is a very good build!
