effing Mobafire screwed up when I was editing, and I lost my Items section as well as my gameplay section >.>

working on fixing that now

Thanks for the +1 :D
the guide won't let me edit, otherwise I woulda gone back and added the part about initiating/ helping your team successfully turret dive. Late late game, when your ult goes for about 1k damage, and their Vayne has 1.5k hp, initiating with the ult is sexy.

And I think I mentioned somewhere about kill securing. And sometimes your team will intentionally let off so you can ult, because they dont want to risk a turret dive/ they want you to get a kill. Karthus is only as good as his team will let him be, after a point.

and yeah, i wanna try jungle karth XD sounds like a lotta fun, with awesome ganks. I dont know about jungle karth in ranked, but normal games, it would be sweet :D

again, thanks for the reply :)

Hey +1 from me.

Great to see a good guide on Karthus. He's is my main caster and its so rare to see a even a decent guide for him. I would like to say that while you mostly covered stuff in items , i typically recommend Rod of Ages over Archangel's Staff. Also a point most people forget is that a great use for the ult is too time it with your tank initiating fights because there shields wont be up or will be popped by the ult and let your team just destroy mow them down. Finally yes dont kill steal but do kill secure(if you play premade you'll know what I mean if not dont worry about it). anyway keep up the good work and good luck. +1 rep if it helped XD.

p.s. try jungle Karthus sometime, its hard but lots of fun.

BTW, I forgot to mention: Karthus is amazing against Tryndamere. He uses Undying Rage, you wait a few seconds, Requiem and laugh. Tryn = easy kills, because he is so aggresive, he always uses his ult.
