Introduction: Me, You, and The Reapers



"Agony, ecstasy, peace. Every passing has a beauty all its own."

Karthus is one of the oldest champions in the League of Legends being one of the original champions released with the game's launch back in 2009. League has come a long way since then and the lich has become an uncommon sight on the rift. Most will give up on him before they understand his full potential. The Deathsinger has always been a rewarding character for those that commit to learning him. This guide will serve to teach you everything the Karthus community has learned over the years.

I have petitioned my fellow Karthus Mains to craft this compendium of all things Karthus. I intend to make this guide the ultimate reference tool supplying a vast knowledge for Summoners truly master the The Deathsinger. Enjoy the Guide! Stop by the the Karthus Main discord. Our community is incredible! Additionally my own discord is listed which has shifted away from league and become an Pathfinder/RP server.

"Dear diary, I met a wonderful ghoul today..."

The Karthus Mains Discord




I suppose I need to talk about myself briefly. My summoner name is The Pale King. I began playing League of Legends around the end of season 2 and first encountered Karthus when I met a player in champion select that was raging about the garbage champion he had just bought, and how he would be refunding him. That champion was Karthus, and something about proving that player wrong had set me on the path to becoming an Elder Lich. In season 7 I played well over 300 games as Karthus with a 63% win rate in ranked. I climbed from the depths of Bronze V to Gold V last season. This current season I have played only 30 games with a 77% win rate on Karthus toward Gold V placing in Silver I in my promos. Additionally I played Karthus a lot before the mastery system but I am currently approaching 800k mastery and actively grinding to 1 million.

-Currently Revising Basic Match Up threats to display Runes, Build Paths, Counter Play, and Summoner Spells against those champions. Will be creating an A-Z index for in-depth match up descriptions of ALL champions, enemy team comp synergies, and common strategies mains of those champions use.


-I will be supplying a Karthus jungle chapter and match ups, I am currently learning how to do this and this is probably the largest and most intimidating chapter for me to write because I am inexperienced in that role. Alongside this I am working on supplying the Match ups for Karthus top.

The Basics of Karthus: Understanding Karthus



Pros


+ Strong Duel Potential
+ Global Ultimate
+ Inevitable Late Game Scaling
+ High Area of Effect Damage
+ Low Skill Floor
+ Powerful Zone Control and Wave Clear

Karthus is a powerful pick in a solo queue environment and supplies unholy amounts of damage alongside powerful utility with Wall of Pain. As a Battlemage Karthus looks to find his way into the heart of the battle and survive long enough to create an extended period of AOE/DPS Defile and Death Defied. Karthus holds the game hostage with his ever looming global ultimate Requiem and can snowball without warning. In lane Karthus is a zone control powerhouse with terrifying duel potential with Lay Waste and incredible wave clear when coupled with Defile.
Cons


- Weak to High Mobility
- Susceptible to Hard CC
- High Skill Ceiling
- Prediction Based Skill Shots
- Ultimate has alot of counterplay
- Reliant on Game Knowledge

In comparison to many mid lane picks Karthus struggles due to his high skill ceiling and lack of mobility. Karthus is a death machine that is reliant on skill and decision making. Karths ultimate Requiem presents alot of counter play and many champions naturally mitigate it by design. Karthus has one of the hardest skill shots Lay Waste in the game to land consistently, relying on predictions and extensive practice in order to master. Unlike other mages Karthus lacks a hard CC ability with only Wall of Pain's slow to provide engage.

"We all have a place among the divine. We have only to accept it."



Death Defied (Passive)

Upon dying, Karthus enters a spirit form allowing him to continue casting spells for 7 seconds. During this time his abilities cost no mana. Defile will be automatically toggled on.

"Gaze upon me and despair!"

Death Defied allows Karthus a window of invulnerability to make plays specific to his characters design. He is able to seal duels that would otherwise be unwinnable. He can flash onto the enemy back line or into an objective pit to pressure the enemy. He can channel his ultimate without fear of interruption. During this ability his standard combo is Wall of Pain Lay Waste Lay Waste Lay Waste Requiem additionally you can cast another Lay Waste at 40% CDR. Karthus can solo Blue Sentinel at level 1 and if he dies he retains the blue buff. Also Death Defied leaves scorch marks on the ground afterwards that enemy auto-pathing cannot cross



Lay Waste (Q)

RANGE: 875
COST: 20/26/32/38/44 mana
COOLDOWN: 1 second

"I will shred your body, and burn your soul!"

Creates a delayed blast at Karthus' cursor position. After 0.5 seconds dealing 40 / 60 / 80 / 100 / 120 (+30% of ability power) magic damage to each nearby enemy. This deals double damage if it hits only a single unit.


  • Lay Waste grants vision in the fog of war when it detonates.
  • Weaving in auto attacks alongside Lay Waste will fool your opponent into watching the autos animation instead of the spell and also raise your damage output.
  • Isolated Lay Waste gives you the strongest level 1 duel potential of any champion.
  • Focus on using Lay Waste to either zone your opponent off farm while you fill your mana pool by last hitting with your auto's Defile or to farm at a distance.
  • Try to predict where your opponents auto-pathing will send their champion. If at any time they are walking in a straight line punish them.
  • An isolated Lay Waste is registered as a single target ability but does not draw minion aggro and does proc the full effects of abilities like Arcane Comet and Ravenous Hunter
  • Lay Waste does not need to hit to be useful. Sometimes faking like you can't hit them will lure your opponent closer to you. The closer you are to the target the easier Lay Waste is to hit.



wall of Pain (W)

RANGE: 1000
COST: 100 mana
COOLDOWN: 18 seconds

"To flee is to suffer."

Karthus creates a 800 / 900 / 1000 / 1100 / 1200 distance wide wall at the target location for 5 seconds. The wall reduces the magic resistance of enemies who pass through it by 15% for 5 seconds and applies a 40 / 50 / 60 / 70 / 80% slow which drops to half effectiveness after 1 second and then decays over the remaining debuff duration.

  • Wall of Pain grants vision in the fog of war around Wall of Pain's pillars but not the wall itself.
  • Wall of Pain's debuff and slow can only affect any given unit once per cast.
  • Wall of Pain does apply to monsters and minions.
  • Placing Wall of Pain at a angle can allow you to hit multiple people during a team fight.
  • The decaying slow on Wall of Pain make it harder to chain Lay Waste you will usually only have time for 1 or 2 Lay Waste until the slow is diminished. The wall is best used against immobile enemies. Karthus is designed to duel other mages.



Defile (E)

RANGE: 425
COST: 30 / 42 / 54 / 66 / 78 per second

"Feel the spirits."

Toggle Off: When Karthus kills a unit, he restores 20 / 27 / 34 / 41 / 48 mana.

Toggle On: Drains 30 / 42 / 54 / 66 / 78 Mana to deal 30 / 50 / 70 / 90 / 110 (+20% of ability power) damage to nearby enemies each second.

  • Flickering Defile on and then off can ensure last hits on minions and enemy champions as it is a static and instantaneous effect.
  • Learning to farm with Karths basic attack allows Defile to completely refund the mana of Lay Waste
  • Defile also restores mana if Karthus destroys an enemy structure.
  • Defile provides the team with a zone of death. Alongside Rylai's Crystal Scepter a constant 20% slow.
  • Defile's healing provided from Ravenous Hunter is suppressed because it is AOE but stacks per enemy. Granting a constant stream of health.
  • Defile stacks Tear of the Goddess at remarkable speed. Toggling it on as you recall will allow the fountain to refund mana as you shop and stack your tear.
  • Defile allows Karthus to clear jungle camps quickly and you can starve out the enemy jungler by stealing their camps. The oldest Karthus trick is to constantly steal their Raptors as they are easy to access from mid lane.



Requiem (R)

RANGE: Global
COST: 150 / 175 / 200
COOLDOWN: 200 / 180 / 160

"Lights out - forever."

After channeling for 3 seconds, Karthus deals 250 / 400 / 550 (+75% of ability power) magic damage to all enemy champions (regardless of distance).

  • Look for champion portraits to draw close to one another on the mini-map to know which lane to watch for a well timed Requiem
  • Sometimes casting Requiem before a battle will weaken your enemies enough to stave off a battle or set them at low enough health to fail.
  • Casting Requiem as the victory screen appears will activate Zhonyha's Stasis effect even if you don't have the item.
  • The beam will be applied to untargetable enemies, although they will not take damage if they are still untargetable when the damage is applied.
  • Karthus cannot cast Requiem if Death Defied's duration is less than 3 seconds
  • Some junglers struggle with their early clear, a well timed Requiem, and a few deep wards can net you early kills.
  • Be aware of your enemies abilities and active items when using Requiem an enemy Zhonya's Hourglass and similar abilities/actives can cause you to waste your ultimate.
  • Requiem does proc the full damage off of Predator but this build is most viable alongside Celerity and champions that can give Karthus large amounts of movement speed such as Zilean or Sivir. Additionally this all stacks with Homeguard and Boots of Mobility. Karth can easily reach 2000 AP with the right items in this build. Not very practical but very fun one shoting the whole enemy team.



Skill Max Order

#1. Requiem
6 / 11 / 16

#2. Lay Waste
1 / 3 / 5 / 7 / 9

#3. Defile
2 / 8 / 10 / 12 / 13

#4. Wall of Pain
4 / 14 / 15 / 17 / 18
> > >

We want to max out Lay Waste because it is our main damage dealer and farming tool. Then Defile as it allows you to lane forever while last hitting minions with our auto's. We level up Wall of Pain last as the first level slow is sufficient until later in the game. Sometimes it is beneficial to take an extra point early in either Defile or Wall of Pain based on the matchup. Defile against anyone melee or anyone that has to get close to you. Wall of Pain against anyone that is immobile without Flash. Don't waste more than one extra point in Wall of Pain after rank 2 the slow is only 60% from 50% and the debuff is always 15%. Take points in Requiem at the immediate available levels.

"Revel in the undoing."





SUMMONER SPELLS
-
FLASH: A powerful mobility spell that is a staple of competitive play. This summoner spell allows Karthus to maneuver around the battlefield and make powerful plays alongside Death Defied. As an immobile mage Karthus needs Flash in order to escape from tough situations. In general this is a staple on almost all champions.
Exhaust: The staple summoner spell of both seasoned and beginner Karthus players alike. Exhaust has a long standing relevance with Karthus as it provides him with safety from ganks and tower dives. This summoner spell also assists Karthus in early duels as it slows and suppresses the targets damage while Karthus delivers the killing blow.
TELEPORT: Teleport is a favorite of higher tier Karthus players. Teleport grants the ability to appear in the midst of a skirmish or even back to a lane to gain a gold lead or defend a tower. The macro capabilities that teleport endows on Karthus is a powerful tool in experienced hands.
"Feel the frailty of life!"



There are 5 core rune pages that work for Karthus and I use all 5 of them based on the situation and preference. Knowing which runes to take and when is one of the most important aspects of Karthus.

Sorcery and Precision




Take this against standard immobile mages. Aery will finish and Scorch will finish off low health enemies. Last stand is mandatory as it provides a boost in damage while in death defied. This is good with the Seraph Singer and Sustain Builds.






Domination and Precision




OR




Take this when you need to duel early and sustain through poke or dps. Ravenous Hunter and Last Stand will keep you alive longer. It is best utilized alongside Sustain or Tank Karthus. Additionally both can be swapped out for
Coup de Grace and Ultimate Hunter when you need less sustain and more global pressure.





Domination and Resolve




Take this when you need to sustain through burst. Your build will need to be defensive to get the most out of this rune page.




Sorcery and Domination




When you need to poke and also sustain in lane. Good in match ups against other battle-mages. Best with Sustain and Traditional Karthus.

-OR-

Rod of Ages > Sustain and Scaling
Rod of Ages rush has stood the test of time as core item on Karthus. The Catalyst of Aeons passive allows you to sustain in lane during tough match ups such as Zed and LeBlanc. This item is best purchased by the 10 minute mark as it takes 10 minutes to scale but provides Karthus with the sustain and scaling he needs to make it into late game. The best questions to ask yourself is "Do I need to play safe?" or "Do I need to stall?", that's when you buy ROA.

Archangel's Staff > Scaling and Utility
Archangel's Staff is a heated topic amongst Karthus Mains. This item provides Karthus with near limitless mana after stacking Tear of the Goddess and early CDR and Ability Power. This item will make Karthus more frail but is the best option if you are confident in your abilities to snowball. It is a staple of the suicide Karthus play style and ramps up his capabilities by providing a shield alongside Zhonya's Hourglass. Unfortunately stacking Tear of the Goddess can take away from Karth's early game.

Sacrifices early game if you first back Tear of the Goddess. Lost Chapter into Tear of the Goddess has been the preferred purchase order. While making Karthus relatively fragile this build supplies defense actives, stronger early to mid game scaling, and a vast mana pool. This build is best against other immobile mages.

Another tank build for Karthus. Expensive but it supplies additional damage and protection. I usually buy this to stall against burst mages in lane and against AP heavy comps. Liandry's and Rabadon's are core to this builds damage.





Offensive
Defensive
Utility





We want this item for the Magic Penetration it provides when stack with Void Staff and Liandry's Torment/ Morellonomicon. It is common to sell boots late game when you have excess gold to reach 900-1000 Ability Power. It's usually best to sell them only if your team has killed an Infernal Drake.

"None can outrun death."



This item seems to have been made for Karthus. It provides him the ability to shred through tanks and squishes alike. It continues to stack percent damage while in Death Defied easily reaching the items full 10% damage. When coupled with Rylai's Crystal Scepter the damage is doubled and can help you melt anti-magic tanks like Maokai and Galio. Additionally this is the core item in all tank Karthus builds.

"What can protect you from the inevitable?"



The Infinity Edge for casters. This item helps Karthus break through his low ability power modifiers on his abilities. It is the go to item if you are snowballing as it will extend your lead and allow you to just burst down the enemy because you are several levels ahead. This item is best purchased after Void Staff. Buy it if you are snowballing to the point where you have the gold.

"When the goin gets tough. The tough get a Deathcap"



More Magic Penetration to help nuke squishes and melt tanks. It is usually best to buy this as early as possible to break the Magic Resist threshold on your opponents Health Bar. This item helps you amplify your damage after you get Liandry's Torment If at any point you see a Spirit Visage or Adaptive Helm in the enemy build paths you need to rush this item alongside Morellonomicon.

"It will turn their mantles to shrouds."



Survivability against AD heavy comps and Assassins. In general this is your go to defensive item. It lets you survive longer in team fights and get a free window of damage when Defile is on and you activate the stasis effect. Defile still drains mana while in the invulnerability. I often stack this alongside Sunfire Cape and Liandry's Torment against AD heavy teams.

"Freeze that moment, on the threshold of oblivion."





This item adds to the stack of Magic Penetration with Void Staff, Sorcerer's Shoes and Liandry's Torment to break down any magic resist being built by tanks and 0 out the magic resist on carries. Additionally this is the go to item against healing champions like Warwick, and Soraka while still providing the ability to nuke carries.


"Pain is the herald of your salvation."




Rylai's is commonly thought to be a core item on Karthus due to his immobility and reliance on positioning to land his Lay Waste. This is a luxury item that is usually bought for its utility if you NEED it. Do not Rylai on Rylai's Crystal Scepter to help land Lay Waste. This item is best when coupled with Liandry's Torment when you need to add to your DPS. I have a tendency to sell boots for this item when I am snowballing hard and can feel the Pentakill coming in my gut. It can also be really handy to help peel for your ADC.

"When death's grip finds you, it clings tightly."



Another item you will sell boots for late game and the more likely choice than Rylai's Crystal Scepter. This item replaces your movement speed that you lose from selling boots and when fully stacked grants a burst of Movement Speed and a 100 AP steroid. It takes 3 minutes to stack the charges on this with Lay Waste but it does charge off your opponents spells. This item lets you break the 1000 AP barrier and you can usually one shot the enemy ADC with Requiem along side this items active and full magic pen at this stage of the game. You usually don't buy this untill 35 minutes or more.

"Surrender!"


A more recent addition to Karth's arsenal Abyssal Mask is a potent sustain item versus high burst champions that can continually use their abilities such as Brand or Syndra. This item offers an aura that allows you to still deal damage when in close proximity while remaining hard to kill. This item is late game oriented and functions as a tool to prevent damage trade interactions while you scale into mid-late game.I often stack this alongside Spirit Visage and Liandry's Torment against heavy AP teams.

"Life clings like a parasite to a soul!."

Being a Death Machine: Learning Karthus



"My pilgrimage begins."





Karthus - The Deathsinger
High Ranged, High AOE/DPS, Battle Mage, Strong Utility, Duelist
How to Learn Karthus
  • Time
  • Practice
  • Knowledge
Speciality: Duels, Global Pressure, Battlemage

Introduction: Now that we've covered the basics of Karthus we have to learn exactly how to be a Karthus. Most people have a bad opinion of Karth because it is very rare to see a strong Karthus. We have already discussed the pro's and con's of selecting Karthus in champion select. But what separates a good Karthus from a bad one? What are the discernible differences between a veteran Karthus and one that's fresh off the boat. Remember that we all make mistakes and some days your game play will be far from perfect. Seek to learn from those mistakes and you have discovered the way.



The Neophyte
VS

The Elder Lich
  • Misses Lay Waste
  • Does not continue to farm or extend kill leads.
  • Wastes Requiem and misses multi-kill opportunities.
  • Death Defied is causing them to feed.
  • Is constantly out of mana.
  • Has little zone control and being bullied in lane.
  • Is constantly front lining or being collapsed on.
  • Misses kill and objective potential due to lack of rotation.
  • Are constantly pushed in and being camped.
  • Does not properly initiate/disengage with Wall of Pain.
  • Lands Lay Waste consistently.
  • Farms Heavily and extends leads.
  • Understands Requiem timing and kill thresholds.
  • Uses Death Defied to extend their window of power.
  • Manages mana and can sustain in lane.
  • Uses Lay Waste as a zoning and vision tool.
  • Can kite and position against enemies.
  • Understands lane rotations and objective importance.
  • Understands wave management and vision control.
  • Uses Wall of Pain effectively per situation.



Practice Makes Perfect

Lay Waste is The Deathsingers bread and butter ability and what defines Karth's kit. Most Summoners see Karthus and immediately think of Requiem as his defining damage tool when in reality Lay Waste is the core of his damage and what differentiates a strong Karthus from a weak one. Below are exercises that will fortify your consistency.
  • Duel a friend in customs or play some hide and seek. When you are learning try and find someone below your skill level. Once you become consistent find someone equal to you. Then find someone stronger than you. Even the champion they choose can be a factor in learning.
  • Go into practice tool lock your level at 1, set your mana to infinite, and practice landing Q's on Scuttle Crab. Scuttle Crab uses autopathing when it flees and this will help train your ability to chain together Lay Wastes and spot autopathing windows.
  • Practice regularly in http://www.aimbooster.com/ or hit some notes in https://osu.ppy.sh/p/download this trains muscle memory which is a large part of hitting Lay Waste.
  • Go into practice tool again lock your level at at and only take 1 point in Lay Waste. Go into the jungle and fight camps try to avoid being hit by the monsters as long as you can while landing Q this is the best way to learn how to kite and evade around enemies in close quarters.
  • The no ult challenge! Go into a game and go into your hotkeys and set your R to a different key. Try and get your kills with only your Lay Waste and other abilities. This will help you break the barrier and not rely on your ultimate for kills. Remember Requiem isn't everything, Lay Waste is where the true power is.
  • Go into practice tool make turrets invincible and lock yourself at level 1 and practice last hitting with both Lay Waste and your auto attacks.

Knowledge

Knowledge is our greatest weapon. Unfortunately I can tell you everything about Karthus but I cannot tell you how to be strong. If you wish to succeed as Karthus you must learn how through trial. Below is an archive of league related videos that are invaluable to learning Karthus.
