Badass build! love it thank you very much!! got 3 double kills :D

Well, I'll rate your guide then. Since I haven't used Karthus for a while, (I'm actually quitting LoL temporarily due to school study) I can't really say a whole lot to your guide, but I can say a few things (you may not agree to me, but it's just my opinions :P)

• List of threats - Kennen, Morgana, Swain, Ryze are completely considered "threats" against Karthus imo.
• Although you mention it, I would completely take AP quints over spellvamp. This is since you have WoA in your build, and 6% spellvamp is way too small compared to what you get from the AP runes.
• I don't find the need of solo baroning. It's SO MUCH safer and effective to have some teammates with you. You can give the enemy team a free kill, or even worse, a stolen baron buff.
• You mention Ghost and Heal as your summoner spells. I say either Teleport, Flash or Ignite. Okay, Ghost is viable. You also mention the use of Surge and also Revive. The problem is not how people will consider you a troll, but it is that you DO become a troll (since they are not worth the effect).
• No offence, tl;dr. It's so packed that I would shorten it (such as taking away the DoT ability list)

Hey, I might have put a whole lot up there, but you asked for it :P
Also, I still gave you a 1+ for the hell load of good work and time you put in there.

Formatting was better than most, I disagree with maxing Wall of Pain second but you reasoned your argument well and I can see how it works. However Defile not only gives your mana back, it also makes you a deadly AoE after you die. Taking heal and ghost aren't actually bad choices like everyone is yelling about, but others such as ignite and surge are certainly better. Got an upvote from me, good job :)

thank you! i like it so much!( When not to play Karthus) ! but may we have more detail on why?? thank you so much!

i stop use replay lol because make lol load slow

Haha, this actually is currently my favourite post here on mobafire. I feel quite honored :) I appriciated you like my guide best, and so do I hehe
Nonetheless, iamlamb's guide provides excellent information on the Karthus subject is well written. I do not agree with the build at all, but you said an important point, which I did in my guide as well, which basically sais: Karthus can be played differently. And that is what makes it so much fun.

And if I remember correctly I even saw you toggling that defile in your Nashor video ;)

Keep on surfin'

Thanks for pointing that out. I'm fixing it on the other screen rightnow

PENTAKILL

Why would you pick Summoner's Insight in your "CRUEL AND UNUSUAL" build if you are supposed to use Heal and Ghost ...?

Besides this, i really liked the options you gave. Nice builds! =)

I'm glad to hear that you guys are doing so well with the guide, I think thats the second penta you guys have gotten with this build. If you'll download LoLRecorder or if you'll just screenshot your high scores I'll post the top 5 plays and scores on this guide.

+1 billion, Played today with this build (swapped the hextech with a deathfire for more ap) and got a penta!!! awesome guide

So let me get this straight? you're downvoting my guide, not because you think it's bad. But because it doesn't match your items? I upvoted his guide and I'm sure he'll do the same once he looks at mine. You just need to learn that there are many right ways to play a champ and you shouldn't sandbag builds just because you like other ones better. I'd appreciate it if you'd reconsider your downvote.
