Karthus is a powerful champion in League of Legends who can play a pivotal role in the game. He is a mage/assassin who is capable of dealing massive amounts of damage from a distance. His ability to deal sustained damage from a far, as well as provide powerful and unique utility, makes him a highly sought-after champion among players.

In this article, we’ll provide you with everything you need to know about Karthus, including his abilities, stats, and strategies:

Overview of Karthus

Karthus is a powerful mage in the wildly popular online game League of Legends. He is a master of death, able to bring destruction to his enemies through magic and his ultimate ability, Requiem.

Karthus is one of the more unique champions in the game and requires careful strategy and positioning to fully utilize him in battle.

Karthus possesses many strong abilities, including Lay Waste, Defile, Wall of Pain, and Requiem. Lay Waste deals magical damage upon activation and then again each time it hits terrain – such as walls or brushes – allowing Karthus players to maximize their damage output with clever positioning. Defile requires mana but deals area-of-effect (AOE) damage while draining Karthus’ own health; this ability must be managed carefully by experienced players in order to make sure that it does not deplete Karthus’ life when activated. The Wall of Pain reduces enemy movement speed for a certain duration, making it easier for Karthus to catch up with enemies or escape from them if necessary.

Lastly, his ultimate ability Requiem will bring a long range AOE damage throughout the entire battlefield – regardless how far away foes are located from him: meticulously utilizing this ultimate can turn the tides of battle in any team fight!

History of Karthus

Karthus is a powerful and versatile champion originating from the League of Legends universe. Dating back to 2009, he has been one of the most popular champions in the game among hardcore players and casual fans alike. Possessing tremendous range, mobility, and damage potential, Karthus is a force to be reckoned with on the Fields of Justice.

Karthus was originally an undead guardian from Icathia, where ancient magics have been sealed away for centuries. In League lore, Icathia was an advanced place that even by Runeterran standards was far ahead in magical development. Eventually a cataclysmic event occurred destroying much of Icathia’s power as well as Karthus’s physical form, transforming him into a lich-like entity powerful enough to rival any other champion in League of Legends.


Karthus is a mage that can excel in lane and team fights due to his high burst damage and utility. He has a variety of spells which make him a great pick for both the mid-lane and the jungle. Let’s take a closer look at his abilities and how you can maximize them:

  1. Lay Waste – Karthus’ basic attack, which deals damage in a small area and can be used to farm minions.
  2. Wall of Pain – Karthus creates a wall of pain which reduces enemy movement speed and damage.
  3. Defile – Karthus drains mana as he deals damage in a large area around him. The more mana he drains, the more damage he deals.
  4. Requiem – Karthus’ ultimate ability, which deals massive damage to all enemies in a large area.

Passive – Death Defied

Karthus’s passive ability is called Death Defied. It allows him to revive from death after a brief delay, which means he can keep fighting even in the face of defeat. When Karthus revives, he will be healed for 25% of his max health and gain bonus movement speed. However, Karthus will have to channel for 3 seconds and cannot attack or use abilities while channeling. If Karthus is interrupted in this process, he will not be able to use Death Defied again for a long duration of time. After the channeling is complete, Karthus will return to life with 25% of his maximum health.

Q – Lay Waste

Q-Lay Waste is an ability seen in many strategy video games. This ability allows the player to quickly destroy a large group of enemies in order to have a better chance at victory. The user typically has limited uses of the ability and must make sure to use it during the right times.

Q-Lay Waste mostly affects standing forces, rather than buildings or other structures. In some games, such as Warcraft III, the ability may also be used to target enemies within an area of effect (AOE), allowing multiple enemies to be hit if they are within range. In addition, Q-Lay Waste abilities can sometimes cause damage over time and confuse enemies in order to hinder their progress toward victory.

Depending on the game, Q-Lay Waste powers may be available at different levels or require a certain level of progress before unlocking them for usage by players. Additionally, certain heroes or characters might have access to a wider range of Q-Lay Waste power than others do; for example a Demon Hunter from World of Warcraft might have more powerful AOE capabilities due their class advantages against certain types of enemy encounters. Regardless, these abilities should ultimately provide players with an edge in difficult battles—as long as they’re wielded appropriately!

W – Wall of Pain

Karthus’ W – Wall of Pain is an area of effect ability that creates a wall with an impressive range—285 attack range at max level. The wall lasts for 5 seconds, dealing magic damage over time and reducing the enemy team’s movement speed by 35%. Additionally, Karthus will gain vision of any enemies caught in the wall for 4 seconds.

This ability has a few unique uses that make it important to understand when playing Karthus. The obvious use is in a team-fight when fighting around neutral objectives such as Baron or dragon (as both teams need to be present to have a successful fight). The wall slows down all enemies caught in it and gives your team an advantage before committing. It’ll also be useful for boxing out opponents running away from your team as you can place it directly on paths/inbetween camps and objectives so they cannot escape until it wears off.

It can also be used to block escaping opponents who are fleeing from a losing fight situation so your team can secure the win. Finally, you can use Wall of Pain offensively if you know where another enemy is running towards and preemptively place the wall before they enter their desired area for maximum effect. Overall, understanding how to effectively use this ability will greatly improve your competency using Karthus!

E – Defile

Karthus’s E ability is Defile. This requires no target and is activated by simply pressing the E key. Defile causes Karthus to drain mana while it is active, but gives him a damage boost, with more power scaling with the cost of each tick. This makes Defile great for waveclear, as well as a reliable source of single-target combat damage when used along with Q and W. It also synergizes well with Karthus’ ultimate, Requiem, allowing him to add area-of-effect burst to his nukes.

R – Requiem

R – Requiem is Karthus’ ultimate ability, a channeled spell that Karthus empowers with his soul. After channeling for three seconds, all enemy champions on the field are dealt Magic Damage equal to a portion of their missing Health.

Requiem can be used to start fights from a distance or finish them off; since the channels lasts for so long, it allows Karthus to take advantage of any repositioning the enemies may do during the cast. The more health enemies are missing, the more damage Requiem will deal. The damage from this ultimate can easily turn fights around and even provide kills when activated in teamfights. As such, it is very crucial for enemy teams to be aware of when Karthus’ Requiem is up and play accordingly.

Tips and Tricks

Karthus is a powerful champion in League of Legends and mastering him can give you an advantage in the game. Knowing his abilities, items and runes are key to becoming a successful Karthus player. This article will give you useful tips and tricks for playing Karthus effectively.

We’ll start off by discussing his abilities and then move on to his build and runes:


The most successful Karthus players focus heavily on positioning. Unlike most champions, Karthus doesn’t possess the mobility or crowd control to easily reach his targets or escape once he does. He needs to make well-planned forays into the enemy team and find convenient spots from which to cast his abilities.

Good positioning allows Karthus players to stay relatively safe throughout fights and use their spells from advantageous angles. Be sure to observe the Fighting Triangle when engaging in teamfights, with the front line and back line spaced out appropriately. Keep an eye on your opponents’ movement during a skirmish and try to stay a few steps ahead of them strategically.

Karthus is also very adept at splitting pushing, as his passive allows him to easily clear out creeps and objective markers while also having enough damage potential (especially when using Defile) to repel enemy champions who might interrupt him as he pushes down structures. Smart placement of walls can allow even a single player on their team to stall multiple enemies while they siege towers uninhibited. When your lane opponent moves away from your lane, take the opportunity and push it aggressively!


When it comes to brewing coffee, timing is everything. If you want to make the perfect cup of coffee, there are a few simple rules of thumb to help you get started.

  • Grind your beans as needed. Freshly ground coffee will bring out the flavor and aroma of your beans more vividly than using pre-ground products. Timing is important when grinding as well – grinding too fine can make extraction difficult, while grinding too coarsely can lead to flavor loss.
  • Once you’ve got the grind sorted out, the next step is finding the ideal brew time for your specific method and desired flavor profile. Generally speaking, lighter roasts require shorter brew times (3-4 minutes) while darker roasts fare better with longer ones (5+ minutes). The variation in these times depends on many different factors such as roast level and bean size, but overall it’s important that it falls within an optimal range in order to get the full flavor profile from your coffee grounds.
  • Finally remember that over-brewing can lead to bitter tasting cups of coffee; so with that said its best practice if you’re unfamiliar with a method or type of roast – start small and increase time slightly until you find just the right amount for your taste preferences.

Team Synergy

When playing as Karthus, it’s important to keep your team in mind. His skills are most effective when used to support his teammates. Karthus is a powerful AoE caster with the ability to focus damage on specific targets. If played correctly, his ultimate can help turn around team fights, especially when used in conjunction with other powerful abilities like Ignite and Exhaust.

Karthus’s passive, Death Defied, gives him a huge mobility advantage if your team has enough CC (crowd control) to keep enemies engaged while your ult is active. This can be a lifesaver in extended fights and takes some of the pressure off your entire team during conflict.

Make sure to pick up items which will provide extra benefit for the entire team like Deathfire Grasp or Liandry’s Torment – these will be more valuable than taking AP carry style items due to Karthus’ sustained AoE damage throughout the game rather than burst damage from single-target ultimates and spells.

Using his Lay Waste ability strategically means even if you don’t get kills or assists you are still providing excellent utility for your team by farming quickly and allowing them opportunities for picks up kills. Make sure that you use Wall of Pain and Wall of Pain followed by Defile liberally for extra zoning force against enemies who are trying to engage or escape from fights without being seen or harassed throughout the game.


Karthus is a powerful champion in the League of Legends. He has a unique set of abilities and can be extremely powerful in the right hands. When playing against a Karthus, it is important to know what to do in order to counter him. Counters are important in any situation when playing against a powerful enemy.

This section will take a look at the best counters against a Karthus and how to use them to your advantage.


Champions are powerful characters that often appear in multiplayer video games. They are usually at the forefront of battles, outfitted with special skills and abilities that make them stronger than the average player. This allows them to take on a wide range of enemies, often without taking damage. While each game may feature a different set of champions, they all have certain elements in common, such as health and mana bars, special abilities and items.

For example, some champions may have large health pools that can absorb massive amounts of damage before they die. Others may possess special abilities that grant extra strength or speed for short periods of time. Champions may also possess weapons or items that grant them an advantage over their opponents, such as slowing or stunning enemies when hit by certain attacks or granting shields to help absorb incoming damage. Each champion is unique and requires different strategies to play successfully; it’s up to you to find an effective way to utilize your chosen champion’s strengths and weaknesses in battle!


When playing as Karthus, it is important to have a strong item build. Each individual game can be different and require the use of different items. Some common core items for Karthus include the following:

  • Rylai’s Crystal Scepter – this item provides Karthus with health, ability power and most importantly a slow effect on his AOE spells. This slow provides good utility by helping his team kite opponents, or catch up to them.
  • Luden’s Echo – this item increases Karthus’s spell damage while also providing movement speed when he casts spells. This item is great at allowing him to hit multiple enemies with an AOE while also providing him additional mobility due to the movement boost it gives.
  • Rabadon’s Deathcap – this very expensive but powerful item provides lots of ability power that makes his spells hit harder and more often.
  • Void Staff – this cheap staff provides magic resist penetration which reduces enemies magic resist, making it easier for Karthus’s spells to land damaging hits.
  • Liandry’s Torment – this item gives lots of Ability Power and unique bonuses such as extra damage when enemies are below 30% HP and bonus damage over time on a target once they are hit by an ability or spell making it an ideal choice in most situations even though its relatively pricey compared some other options.


Karthus is one of the most versatile champions to have ever been released in League of Legends. As a low-cost mage, Karthus can be played in any position, from support to mid lane, but he tends to shine the most when taking up an offensive role. Karthus is designed as a champion who can dish out lots of damage at long distances while still being able to survive sustained fights. To excel with this champion, you need to be aware of the options available and know how best to execute them.

When playing as Karthus, you should always focus on your abilities and make sure that your ultimate is used whenever it is off cooldown; this will allow you to put out massive amounts of damage quickly which will help your team secure objectives and take down enemy champions quickly. Moreover, Karthus’ passive allows him to become extremely durable if he kills enough enemies early game which then allows him to tank up if needed in late game teamfights or siege scenarios. When facing counters like tanks or healers, it may be worth considering building a Rabadon’s Deathcap or Liandry’s Torment in order to solidify your damage output even further than usual.

Finally when considering opponents in lane make sure you are aware of their options and plays they are likely trying do against you; take note of cooldowns and important actions such as how low their health bar is and what items they have bought; all these pieces for information can go into formulating an effective strategy against them both pre fight (denying farm) and during combat (bash combos).


In conclusion, Karthus is a great champion that enables the team to deal powerful and sustained damage with his passive and spells. He has an array of advantages including the ability to bring down tanks, great sustain in fights and the ability to farm safely with walls. All in all, Karthus provides great utility for your team. His high damage can turn the tides of a game and he has a wide range of uses from siege to team fighting.

Just remember that you need a lot of practice to be able to play him optimally and he takes some getting used to for newer players. If you manage to learn him correctly, though, you’ll be one step closer towards becoming a master LoL player!
