I love playing as an orbital death laser. I've only done it once, but it was the most satisfying thing: I'd just finished telling my team, in ARAM, that they need to stay near me when I die (as Karthus) and force the enemy to either fight in my Defile aura, or fallback. As I hit enter, my team pushed them back to their first tower, some of them were quite low. I seized the moment and dove their tower, throwing up Seraph's Embrace to ensure I got right in their ranks. My team engaged with me and between my defile and spells and my team's attacks all of their champs were hurting bad. As soon as the tower killed me, I started Requiem.
I'd never heard it before, but if you kill enemies fast enough the announcer skips the different levels of killing spree, skips "An enemy has been slain." There was a bang from Requiem landing which was immediately followed by "PentaKill!" that was all that was said. It was beautiful and a direct result of teamwork. I am not claiming credit for all those kills. I simply secured them.
I always thought of this one :P
Just played Karthus in URF Mode with the Laser Finisher. GG Double Orbital Death Laser
I had a Karthus game where I never died. I'm not entirely sure how it happened, but a 16/0/17 Karthus was a beautiful thing to play and behold.
in urf its more like a gatling gun followed by an orbital death laser of doom
"May death free us all ! "
bangs head on desk I. bang HATE. bang KARTHUS!!!
