Please update this guide, i loved your jungle guide and i think you should put some time into updating so others can enjoy it too

I was wondering if getting a dorans ring would be better for better harrass and mp regen early game over boots + 3 hp in solo mid. Can someone give me back some feedback? thank you

Thank you for this guide.... when I started with Karthus (who is my main champ now), this guide was the main information-source for me; it's maybe one of many reasons why I play Karthus with Clarity and without Archangel's Staff. Few day ago I've registered to mobafire, so I upvote this guide now (even if I wanted to do it long time ago).

Someone might have mentioned this before (no way im going through 23 pages to check) but your first solo mid build is about 21% over the CDR cap. Id suggest changing the boots and 2/3rds of the glyphs, or swap out the Morellos for something with more AP and health like Ryalis / Rod of Ages.

I find heal really fun to use early game for Karth, I like to intentionally get myself down to low hp near lv 2-3, still staying near creeps for exp and money, but giving that irresistable temptation to kill a squishy at low hp really shows you what kind of player they are. If they attack, offensive, if not, defensive. If you find that they are defensive, pop a pot and forget anything ever happened. If offensive, 9 times outta 10, they'll die and you'll live. Now simply recall and teleport. Most people would disasgree with me but imo, i think these 2 summoner spells are perfect. Like someone said abovr, i use my heal to live a couple more seconds (before my brother(yorick) casts his ulti on me and gives me 10 seconds) and easily get 1-2 more kills while alive, and maybe 1-3 while dead, if not, i zone them out for 7 seconds, usually enough to get a turret. Also, about your (while dead) combo with ***, 3-4 Lw and requiem. I find that quite unreliable and maybe this is where all those bad karths this week found their build. Tbh, this was my karth build when i first startes before changing it into my own playstyle, so i thank you for the foundation you provided me. Also, i also disagree with the fact that you use requiem to start fights, that's not smart. Chances are that theyll be left and enough life to be intimidated, that's all. What good is half their life if theyre going to all recall? Id rather my teammates do the dmg, retreat if they need to, and then use requiem to finish them off or scare them off. Just my playstyle, +1 anyways

Really nice. It's obvious that you put a lot of efford into this.

I would consider as an other alternative for Summoner Spells the Flash + Heal! Combo.

Flash is obvious but Heal is due to following reasons:

The Team fights are starting around you, so you can easily heal 2-4 people + yourself with it.
The increased survivability gains you around 2-3 seconds in a fight, which are 2-4 Lay Wastes + the damage from your Aura, this is more then Ignite will ever deal.
And last but not least, it can save your *** and yeah, sometimes this is worth more then killing someone if you are on a killing spree.

I'm Lvl 22 and it's just ridiculous...

+1 love the guide espicialy the jungling build its so much fun to jungle karthus =D

this guide may not be updated yet its still awesome my last game i got a penta and 4 quads :)
