With riven, I have a starting combo multiplier of 4x. [Gladiator Rush] can also be replaced with, [Jagged Edge] for more slash if needed (more than likely does). [Buzz Kill] with this setup only grants an extra 32 or so points of extra slash over [Jagged Edge], and uses more capacity (which would need another forma for). So, I went with [Jagged Edge] as the choice for more slash. I've yet to fully test this build, and it currently exists now just for me to see the stats. So, use with caution if you even have the SAME EXACT riven I put on it. I added info if people are wondering why this exists.
