"wow, did you even read more than the title?" (:

Sorry mate, completely wrong.
Everyone knows you can't build Katarina AD.
You should focus 100% on AP.

Thanks for your feedback amd vote, I'll check this :)

An interesting thought, if nothing else. Pretty well built, imo. Needs a few fixes here and there, but largely alright.

20/9/1 masteries don't give you Executioner ;).

wow, did you even read more than the title?

Katarina = AP carry

Hi, wow the first "-1"-comment with a good statement, thanks! :)

First of all: this isn't a Hybrid-Build. I'm focussing on AD, there's just one item with AP I always buy ( Sheen ) - all the other items are just counter-items like Haunting Guise.
It's really important to underline that my AD-Kata build is not about dealing autohit-dmg - you deal Magic-Damage + Sheen (= perma harassing).

And yup you're right, my build is bad against melee AP-champs like Fizz or Akali. But on the other side I'm able to win against champs where AP-Kata would be totally lost. :-)
I've played so many games with these build now and all I can say is that about 80% of my RANDOM Kata-games didn't include a loss of the mid-lane.

The build is a little all over the place. If you want to build AD you should lean more heavily on defensive builds and avoid trying to play hybrid, it works poorly with kat. This sort of build is only useful against match-ups that are difficult for AP burst kat (cho'gath etc.). On the upside presentation and appearance of the guide is probably some of the best I've seen. Match-ups are what they are with a oddball build - fizz/akali who are a joke for AP kat's ranged poke are admittedly disgusting to deal with if you're going to try for this kind of close ranged auto-attacking build :/

Thank you for your comment, I really appreciate it! =]
Yeah, the jungling route will be completly reworked because of the pre-seaoson patch.

AD-Katarina is about constant harassing, not about nuking hard. You still have a really good nuke in team-fights (you can kill squishies very fast because of the good AD-Ratio for Death Lotus)
I would never play AP-Katarina again after the rework - AD-Kata is not easy but if you realise how imbalanced Sinister Steel is you can easily dominate the lane. Riot should decrease the movement-speed buff of this spell, it's too strong in early-game because many gankers can't reach you. ^.^

Your first point: I didn't update the masteries, they are normally with Executioner, but my build was deleted because of the latest patch.
This is the important point about this jungle-build: you're able to use the FULL offensive masteries with Lifesteal-Runes because your damage is high enough to regenerate yourself while jungling with auto-hitting.
You can still jungle with Defensive-Tree and Armor but it's really slow.

Your third and fourth point are a nice idea to improve my guide - I've just tested many ways to jungle with Katarina - and the Armor-Pen-Runes + Lifesteal-Runes were the best way I could jungle wiht Kata.
But I have to say that Kata-Jungle is just some kind of a fun-build - my focus on this is guide is about the Lane-AD Katarina.

I would not like the style of playing Kat with AD and trinity force. I'd rather just nuke people down. It's pretty funny to read all the uneducated comments people have been leaving you though. Here's my suggestions:

First off, you need to change the masteries. I WISH i could go 20/9/1 and still get executioner that would be awesome :P

Second, I was interested in jungling until I read "If you don't have at least two of these essences (very expensive!) you shouldn't give it a try. :)" Don't discourage anyone based on lack of anything... it's just bad practice when writing a guide. I just did a route and did fine.

Third, Kat does not use mana. Mana is the primary reason someone starts at the blue buff. The cdr would give you maybe one extra use of sinister steel per camp. In my opinion you should by jungling only the smaller camps for two reasons. It will make your jungling easier AND it will leave the buffs up for when you ARE ready to gank you can do so with extended buff duration.

Fourth, you should jungle with MR reduction as you can decrease something's MR below zero and do bonus damage to them seeing as all of kat's abilities deal magic damage, even sinister steel

I hope I've been helpful in possibly improving your guide ^_^

Thanks for your comment! :)
Yeah, I just have the chapter "How to play Trinity-Force Kata" which contains some information about her playstyle with Trinity-Force.
I sell Cloth Armor in the end - perhaps there's a good item that you can combine with it but I'm really unsure about a better alternative. Cloth Armor is just the best way I've found to start jungling with my build if you want to gank early.

This matchup-thing is a very good point I should add into my guide! There are enemies that you can easily dominate with early maxed Sinister Steel like Veigar - but there are melee-ranged AP-champions like Fizz or Akali who can be disastrous.

Good guide but I can't find in-depth information about jungle Katarina. I took a glimpse of the chapters, what do you do with the Cloth Armor(jungle build)?
And why don't you have some match-ups? I know how to play Katarina but I really think her playstyle changes with Trinity Force. That means, the match-ups change too. You can go more in-depth, you just say the basics and this doesn't mean this is comprehensive. I am in a hurry, I will come later on with some arguments!
