I think you never jungled karthus. I do it sometimes and with this build I had the most sucess. still you can downvote this guide for many other reasons. before downvoting a guide for the items, (except it is obvious they are bad (6rabadon on vayne)) you should try them out after a game where you used your own item choices for that particular champ. then it still depens on the way you play the game. after if you think the item he use are terrible then it's your opinion. I'm not going to judge you about that

Fast junglers like Shyvana and Karthus do not need a Machete to clear. In addition to that, Karthus can't build any items out of the machete. Spectral Wraith is a subpar item for Karthus, unless you're planning to not be an APC and just bumrush objectives by stacking spellvamp. Elder Lizard isn't a good choice for obvious reasons, and Ancient Golem doesn't give the stats needed for an APC.
RoA perfectly fine on a jungler, your clear times let you farm fairly well, and as long as you aren't ******ed with your ganking, you'll get a decent amount of gold from it too. I've never had an issue getting RoA and Tear before 20 mins.

Thanks for bringing this to my attention though, I'll be sure to add this in a section on my guide.

You're right the items aren't bad. They're terrible. RoA on a jungler is bad, not starting machete on a weak jungler is even worse.

the items aren't bad, there's much other stuff that's more important where you could downvote for ...

Downvoted for rubbish items.

on the guide the part on the right wouldn't be cut off, here is only not enough space so everything can be seen

Thanks for the suggestion but I honestly think that the planners look horrible.

everything related to karthus jungle has to be explained the best way possible! every item you use, for what reason you use them and what it provides you. don't forget about how to gank with karthus, since he only has a slow, wich once missplaced is useless for you.

edit1 : for your runes section you should use the rune planner
www.mobafire.com/league-of-legends/rune-page-planner

wich in your case would look like this.


same for your masteries, use the masteries tree planner
http://www.mobafire.com/league-of-legends/mastery-tree-planner

wich in your case would look like this
edit 2 : for your skill sequence you can see it in my first post already ;)

Thanks for the input, I originally left out stuff like detailed item explanations and ganking methods, etc. because I felt that they weren't really related to Karthus and more of how to play the game in general. I'll add it in now since I guess it does help play Karthus better.

If your gonna use that title at least have this SOMEWHERE in the guide xD

Nice written sections. Try to elaborate more on things like runes and masteries despite it seeming somewhat tedious given the stagnant meta of AP mids.

Upvoted for promising content.
