some people make accounts to comment and vote up builds, like me.. I havent posted on any others because half of the time i end up making the build up myself after a rough guideline.. But this guide explains alot for me and i actually follow it and do well. no need to be so negative... just because someone hasn't been around long doesn't mean that they are fake people or being made to do anything. it just makes you look silly for jumping to conclusions. if you want screen caps i can give you some.

They are my mates from ingame or team mates who i linked to the guide who i helped so they voted it up not like any of the accounts where mine.

Eu West: Zerockk thats my summoner profile should be on there

ok so i was kind impressed until i noticed that all the other votes on here are from people who joined the day of your guide or the day after. Also it doesn't say anything about you being from the EU west server in the guide or your profile so that leads me to believe that your spamming accounts and artificially voting up your guide. As such i am changing my vote to a down vote until im am CLEARLY proved otherwise. please stop being so noobish and let REAL people vote on your guides

AHMYGOD - best guide ever written i used to suck hard with karthus but now i am pro... racking up the kills with my big orange ball..

I love you Zerockk best guide ever, you must be the best karthus on EU west.

Peace Out

Yeah I rarely get to that point in the game, If im versus alot of ap i often take a defensive item maybe i should create an optional item section since i myself don't always go for that

Nice guide but you are overlooking a couple of things. Karthus is one of my mains and ive started moving away from archangels staff and have replaced it with rylias crystal scepter for the added hp and slow effects. Another point is that karthus's ult is often more useful late game as a team fight initiating in combo with your tank initiating,or for example: evening the odds for your teammate stuck holding that last bot tower 1 v 2( though it really comes down to your team play style and your timing with stuff). Also one last thing i noticed is you dont take any more lvls in defile until after you've maxed lay waste. While this makes you do more damage with lay waste early if you build them up together simply for the manna regain (i dont usually toggle defile until lvl 9 or 10) you have virtually indefinite lane sustainability. Good build overall though, always nice to see a fellow Karthus fan keep up the good work.

p.s. jungle karhtus is also very viable.

Very nice guide, Funny aswell! It worked for my first 2 games so far hope it carries on i like to get a banshees to survive more but its pretty much the same nice guide +1

This guide really helped me with playing Karthus mid :) Mucb better than the other builds.. thank alot!
