Thanks for the input, everyone!

I like that, sn0wwarrior! I'll make the change to the sequence.

Either you're stupid, or you're that special guy.

The reason why he/she takes Philostone on Karth in the early game is because of the Hregen, Mregen and GP5, while swapping it out for a Morello's or Zhonya's in the lategame, you fool.

Very nice build, Its nice to see people updating builds on older champs such as karthus. The only difference I'd suggest in the build is switching the order of rabadons and Archangels. Im not sure how you'd use your mana effectively enough to maintain your presence throughout the mid-game. However Great guide with good info. +1

ok at this point im not voting, and let me preface this as Karthus is my main caster.

#1. Not a big fan of Morello's Evil Tome. CRD is nice on karthus for his ult but cdr is not a necessary part of a Karthus build due to main damage should come from Lay Waste and Defile which have no cd worth speaking of.

#2. I see your point on Philosopher's Stone, not disagreeing, im just not a big fan of that route (again not saying its bad, i just dont like that route as much and im not down voting or anything like that just because its different.

#3. this more of a suggestion you can try if you want, and that is take a 2nd point in Defile instead of Lay Waste at lvl 5. You will find you are ultimately much more spam able and it doesn't hurt your damage output.

just some thoughts there, again not voting at this point.

******** philostone on karthus your argument on that is ********

And thank you for posting your build! ^^ I'll definitely keep an eye out on you and your future posts!

Thank you so much for giving it a shot! :3

SUDDENLYVOTECOMMENT

Well, I tried this build (Along with AS/MS Ninja Soraka on Dominion, but that aside) and I car safely conclude that this (And ninja Soraka) work well. :>

Back when I played Karthus I always picked Amplifying Tome and Hextech Revolver over Philosoper's Stone in the early game because of the AP and spell vamp, but this works as well. :>

+1 and fav'd. I can finally play Karthus in a not zombie kind. :>

Thanks very much!

I don't understand your confusion- you sell philosopher's stone for a final item every game; it just doesn't need to be sold until then.
