Late Q max.

Don't like the masteries

No, just Kass. And he's not broken in general, just to Karth, hence why I said as such. If you think Karth's main strat is to flash suicide... uhhh... you need to play against better Karths. Just saying.

I like how you're saying certain champions and skills are broken or overpowered. You've written a guide about Karthus, a mage whos main build is Flash suicide into the enemy team That's not broken at all, is it?
+1 for the guide. -1000 for the character.

The guide has been appropriately updated. Information on the newer champs(like Nocturne, Lee Sin, Rumble, etc) will be coming within the week.

hey man, just wanna point out a champ for the Requeim Counters section. Nocturnes spell shield is exactly like sivirs. very in depth guide thats for sure

gd build especially items and masteries... although for runes i went for Mark of Force, Seal of Clarity and Glyph of Force and did much better then the ones u have. Still gd job keep it up +1

I've seen jungling Karthus before, and it works quite well. Being as Karthus has a lot of power early game, and easy mana management with Lay Waste, it can be really awesome to see. I know of one guide on here that builds Karthus as a jungler, and when I tried it out, it actually worked quite well.

Since Karthus can solo many of the monsters on the map earlier than most characters(for example the dragon), he can surprise people. I believe it was actually once accepted that Karthus was one of the strongest junglers up until the nerf for Strength of Spirit if I remember correctly. Though to be fair, I've rarely played exclusively jungle, so testing to see whether or not this still holds true would be something worth looking into.

The only problem that I have with a jungling Karthus isn't the jungling itself but rather the fact that since he's so much squishier than 9/10's of the other typical junglers, champs like Rammus, Shaco, Udyr, and Olaf can get easy kills off Karthus while he jungles. In the future however, I will go into jungling on this guide. Thanks for the input! =)

Well by far the most in-depth guided I have ever seen. I am a avid Karthus player, and I believe this is the best guide. I don't personally like the item build, but that is just play style. great job, I have learned alot and even branch out to outside lanes versus always taking mid. I have also designed an for a jungling Karthus. I would like to see your thoughts on a idea.

Great idea. Thanks for the tip. I'll be sure to update the guide with Requiem counters soon.

If you mind, adding a part like "Requiem Counters" would be more than a success to your guide. Usually the enemy who can avoid your ultimate most of the times is Vladimir and/or Shaco. Popping Sanguine Pool right in time is crucial and thanks to it you can avoid a massive damage/finishin blow.

good guide. **** karthus. noobchar. srsly. +1 for the guide -100 for the char.

build looks pretty solid man, thanks for the guide
