I have fixed some of this points, you are right I took the catalyst instead of the Blasting wand but I am going to try also to skip the rod of ages and to rush the rabadon but I will see how it is. I will continu updating my guide tomorow just let me some time to finish to fix all of that ^^

For now I won't vote, but there are a couple things you need to address in order to have a comprehensive (and good) Karthus guide.

1- Karthus counters and how to counter them. (Numerous champions can ult-dodge when karthus requiems. Fizz, Sivir, and Shaco just to name a few.)

2- Tear of the goddess and Catalyst at the same time. The majority of people go one way or the other because they are gold intensive and there isn't much AP return for the investment.

3- BB coding (NEED MOAR!!)

4- Instead of just posting a video of someone else explaining how to karthus, you need to explain. otherwise this isn't really your guide, its a bunch of different guides from everywhere frankenstiened together. Its alot like plagerism. Be original.

All of that being said, I am happy to see someone else using Ghost/Heal on karthus. Its underrated by a long shot. Fix some of the stuff I said and I'll +1 your guide. Also check out my guide here

Overall a good guide, as said above, dont use too much color and explian with words the highlights of the video you provide.

Good information. However, don't use all these random colours as it makes your guide look unprofessional. Just highlight the important keywords and it'll look fine. If you want an example my guide is ok.

+1 for effort.

Iamblamb first I dont get my boots on first item because you need mana regeneration but I buy it the first time when I back to my chop. Of course if the enemy keep harassing me I back to shop earlier and buy boots because I know that you can't do all the time the same build you have to adapt it ! Like I have wrote in my item description I make my Archangel's staff at that moment for his passive ... I have tried to make it before/after but that is the way I prefer. For my guide I have passed something like 10 hours to make it + the BB code so no I haven't took 35 minutes for doing it. I post that video because at the begining I have look some tips and tricks on the internet but I had some problems to play karthus ... But a day I watsh that video and I have understood how to play that hero right! You need to see this hero in action or you will never understand how to play him !

Yes you are right ;) next time I will kill you with my Cho'Gath and you will upvote my guide ;)

Got killed by da Karth of BuckRoger recently. Summoner name is Adorona

There are a couple issues I have with this guide. First of all, karthus is deathly slow without boots, and needs them to be able to dodge harass from people like lux and escape from junglers. Second, you should take Archangel's right after RoA (I never use RoA, but I guess thats a preference). You rush AA's because you need time to build its mana and in turn it's AP. I think you need to go more in depth with some sections, and it seems like its the easy way out to just post a 35 minute video in the section titled "How To Play Karthus". How about some bulletpoints. I won't downvote for now, but this needs some improving.
