Introduction

Welcome to the 4 vs 0 Karthus guide. This will lead to a 100% victory if some requirements are met. It's what people call a "Glass Cannon" build but with some tweaks.

WARNING!!
This will work:
  • If your team has a tank and sufficient CCs, which it should.
  • The enemy team is not full of tanks/off-tanks.
  • The enemy team doesn't stack tons of magic resist just to counter you.

Pros / Cons


Pros

  • Insane damage.
  • Fun to watch enemy team rage at your ulti.
  • Cheap build due to easy creep farm
  • One Teemo dies on each Requiem
  • Another Teemo dies on the other 2 LoL servers in a random Dominion match.
  • 1 x Lay Waste = 50% of Squishies' health
  • Defile = Vacuum cleaner
  • Tons of damage before you die
  • Tons of damage after you die






Cons


  • So squishy that as much as a creep sneezes, you die.
  • Tanky enemy team = you are useless.
  • Easily countered by Soraka.
  • Easily countered with Zhonya's Hourglass.
  • Boring early game farming.

Runes

For runes i strongly recommed:


Runes

Greater Mark of Magic Penetration
9

Greater Seal of Mana Regeneration
9

Greater Glyph of Ability Power
9

Greater Quintessence of Ability Power
3





Greater Mark of Insight

These + Sorcerer's Shoes will give you 28.55 magic penetration. Squishy champions with no magic resist items(or m.resist scaling) have 30 magic resist. This means true damage for you.

Greater Seal of Replenishment
Greater Seal of Replenishment

These will give you enough mana regeneration to help you farm and harass on lane early-game until you get Tear of the Goddess and blue buff to charge it



Greater Glyph of Potency

A lot of Ability Power for more effectiveness on Lay Waste. Better harass - guaranteed last hit on creeps.


Greater Quintessence of Potency

A lot of Ability Power for more effectiveness on Lay Waste. Better harass - guaranteed last hit on creeps.

This is a near-standard 21-0-9 AP carry page. I will explain a couple of things in more detail:
  • 4 points on Archmage is a must, as this build will give you TONS of AP.
  • 4 points on Swiftness is a must as well for the gamestyle you are going to follow and will explain bellow.
  • 1 points on Runic Affinity . You are the AP carry, you will be taking blue unless there's another teammate that cant offer more than you casting Requiem like no tomorrow... Also, the first time you will get blue buff, you WILL have your 1st Tear of the Goddess bought. Spam skills and charge it.

Items

Now for the good stuff!

Your final built will look like this:

Item Sequence











Archangel's Staff
3100

Rabadon's Deathcap
3800

Archangel's Staff
3100

Archangel's Staff
3100

Archangel's Staff
3100

These combination of items give the Maximum AP a Karthus can ever get.
AP at level 18 with tear charged: 1149.2




Explanation:
  • Karthus is a very squishy champion but has a lot of potential for some serious damage output. For the game-style this guide is about a rod of the ages (as many would suggest) would not help and only drag your damage lower.
    The idea about stacking Archangel's Staff is that its passive + the mana lets you take your AP sky-high.

  • You will not get the mana from the many tear of goddess components but the 3% mana = AP stacks since its not Unique Passive.

  • Each Archangel's Staff you purchase gets more and more stronger.

  • Now take all that AP you ve built up from 4 x Archangel's Staff and maximize it with Rabadon's Deathcap

  • In case the enemy starts stacking magic resist, sell 1 x Archangel's Staff and replace it with a Void Staff.



Abilities Damage:






Additional potions in case you reach full build and game is not won yet:


Buy these 3 in the following order
More AP + cooldown reduction is GOOD! Note that at this point it might not be a good idea to be the one getting the Blue buff, since you are going to kamikaze youself to devastate enemy team.


Some health boost to make your roaming half a hit easier.


Attack Speed! You + enemy Turret/inhibitor/nexus = GG

Priorities:

Needless to say you max Requiem whenever possible. Give points at levels 6 - 11 - 16.
  1. Max Lay Waste first.
    You will be able to get easier last hits early game and do a LOT of damage from a great distance in teamfights/ganks etc.

  2. Max Defile 2nd.
    With this at mid/late game you will be farming creeps at a ridiculously high rate. It looks really funny when sweeping over a lane. Its like a Vacuum cleaner picking up creeps.

  3. Max Wall of Pain last.
    Some would say, why not give this some points earler since the length and the amount of magic resist reduction increases? Simple: what use will it make, if your other skills dont do as much damage as they should in order to take full advantage of this skill. This is a great skill for escaping or catching fleeing opponents.

Summoner Spells

At first, the summoner spells i chose for this build might look weird for you but i will explain shortly why they are the best for what you are about to do in-game.



  • Teleport to save any turret under attack by creeps + enemy pusher. Switch defile on and farm 2-3 minion waves and go buy a Ferrari with the gold you've earned.

  • If there is an opening and the enemy team is busy at the one half of the map, use teleport to backdoor any turret available on the other half. Now, before you go comment "Bd karthus? lol rofl noob" etc. The damage done to buildings is equal to 40% of your Ability power, that means 40% of 1149 = 460 per auto attack. Your defile will not let any creeps bother the ones you've already pushed under the enemy turret, so ~4-5 seconds and bye bye enemy turret. The enemy team will not expecting a Karthus backdoor so the response to that will be slow and most likely allow you to get turret and back to safety.

  • Situation: The way you will be playing Karthus will most likely leave u dead after a teamfight. In that case, you will respawn first (also with help of Good Hands ). In late-game(nexus left) if that happens and you get the chance, teleport to enemy base and finish off their Nexus.
    Note: It mind sound crazy to you, but has happened many times to me with this build.

Playstyle

This is the main reason why this build is so OP.

{ Early Game }:

  • Focus on farming like your life depends on it (which it does)
  • Watch lanes and chat for your teammates to call for Requiem and get some kills or assists. Careful to observe the situation and make sure your target WILL die weather it is from you or your teammates waiting for your Requiem to strike.




{{ Middle Game }}: Important Note: If your team is not doing so well and you don't think you can win a teamfight like that, consider casting Requiem the second the fight is initiated. This will give your team a MAJOR headstart and most likely Ace. Make sure you stand somewhere safe to cast it otherwise an enemy champion might interrupt it.




{{{ Late Game }}}:
Real fun starts here!

Steps to follow:
  1. Get in position behind your team or hidden in a bush.
  2. YOU initiate the fight by pinging or informing your team beforehand or this will end up in a disaster.
  3. Ghost + Defile On!
  4. Run INTO the enemy team and place Wall of Pain in them making sure you will place yourself inside the wall too.
  5. Spam Lay Waste until you die. Spam 2 more times after dead
  6. Hit Requiem





Congratulations!

  • You are dead.
  • Your team Aced. (remember the 4 vs 0) ;)
  • Minimum 2 Turrets down every time this is done.
  • GG.
