Welcome to Kyle's Karthus guide

Me:

I'm not a Pro player,I'm only silver but I am no noob.
I play this game sometimes seriously sometimes for fun but either way I play to win.

I mostly play with friends and I play any lane but my best lane is top

-Passive Death Defied
-Ulti(Global) Requiem

Karthus is a ranged AP Carry,he has a set of abilities to help him poke his enemies down to low health which is good for early game because his early game is not so good
