[11.1] Karthus Jungle Guide | Not just an R Machine

By nZk01
Why would you even want to play Karthus?

First of all, why would you want to play this Champ?

- Best Jungle Clear in the game
- A lot of outplay potential
- Your ult is one of the most dangerous and annoying abilities in the Game
- You're even useful if you die!

Overall, Karthus is generally hated as he has an insanely fast Clear and can legit gank all Lanes with just pressing R at once, you can AFK farm the whole game and just do nothing but ult and still be more useful than the enemy Jungler.

If you get fed on this champ, you can instantly 1 shot every enemy below 50% HP which is really funny to see :^)

Pros and Cons Back to Top

Here are some Pros and Cons about Karthus!


- Very fast Clear
- Scales very well
- Good early damage to fight enemies and contest objectives
- Can instantly 1 shot targets at 50% HP if fed enough
- Useful after death
- Wall gives Vision
- Doesn't need Leash


- High Skillcap/Hard to master
- Ult has low Base damage and high cooldown early on
- Invades can really destroy you
- Items like banshees, Edge of Night and Zhonya can **** you over
Abilities Back to Top

In this Chapter I will explain the Abilites and how to effectively use them

Death Defied/Passive

When Karthus dies, he remains active for 7 seconds, making him unable to move, Autoattack or to use item effects, but becoming untargetable and invulnerable for the duration as well as being able to use abilites at no cost.

If Defile has been learned, it will remain toggled on for the entire duration at no mana cost.

You can abuse this in fights, especially later on.
As example, you could Flash into the enemy team for permanent AOE Damage and easier to hit Q, besides that, I would recommend dying before using ult if your in a teamfight or at the risk of getting CC'd.

Lay Waste/Q

Target Range: 875
Effect Radius: 160
Cost: 20/26/32/38/44 Mana
Cooldown: 1 Second

After a 0.5-second delay, Karthus detonates the target Area in the cursor's direction, dealing 45/65/85/105/125(+30% AP) Magic Damage to all enemies within, dobuled when hitting only one target.

This spell has a really low CD and low mana cost and even gives you vision for a short amount, abusing that is Key, especially as Cheesing can really destroy you.
Just Q into a bush or somewhere you think the enemy could be to go sure he isn't there.

Wall of Pain/W

Target Range: 1000
Cost: 70 Mana
Cooldown: 15 Seconds
Wall Lenngth: 800/900/1000/1100/1200

Karthus Creates a wall at the target location for 5 Seconds and grants sight around it.

For the Duration, all units who cross it are both slowed by 40/50/60/70/80% for 4 seconds, reduced by 50% over the first second, decaying over its duration and lose 15% magic resistance for the same duration.

This Spell is mainly used early on for vision or as a slow when ganking, the range is really helpful later on as u gain a lot of vision by using it throughout the whole game and when you die, use this ability first if you're allowed to.


Effect Radius: 425
Cost: 30/42/54/66/78 Mana per Second

Toggle Off: Karthus restores 20/27/34/41/48 Mana whenever he kills a unit.

Toggle On: Karthus deals 30/50/70/90/110(+20% AP) Magic Damage per second to all nearby units.

This Spell is probabaly the most important on Karthus Jungle as the abusing of this spell makes a gigantic difference between a good and bad Karthus player.
You have to abuse the Mana refund early on a lot as its really insane and helps so much to clear your Jungle.


Effect Radius: Global
Cost: 100 Mana
Cooldown: 200/180/160

Karthus channels for 3 Seconds and deals 200/350/500(75% AP) Magic Damage to all targetable enemy champions upon its completion.

This is the Main spell and makes Karthus what he is, the usage of this ult shows, just like your E, weither you're a good Karthus or a bad one.
This spell can be used as an execute or a Zoning tool for important fights and Objectives.
Pathing Back to Top

Now we'll talk about the Pathing.

The Pathing of Karthus is legit every game pretty much the same, you start Blue without Leash, then clear Gromp and Wolves, head to the other side of the map and full clear that side too, then gank bot and ask your Support to come with you to maybe get both crabs.

If you start Redside you can start Red, obviously without Leash too, then clear Krugs and raptors and head to your botside to full clear that one too, then gank bot and do the same as before, even though I wouldn't recommend this pathing as a Level 2 Gromp is way better than level 2 Krugs and you kinda waste time walking from red to krugs to raptors instead of just going a straight line while jungling.

Here's a Video of Malice (Korean Challenger Karthus player and former Proplayer) showcasing both of the Clears:
Playstyle Back to Top

In this Chapter we'll talk about how to play in the stages of the Game

Early Game

In the Early Game you want to focus on Farming and getting Objectives to Scale into the Mid/Lategame

Mid Game

In the Mid Game you focus on taking Nash or getting the Dragon Soul and try to abuse your ult to kill the enemies in fights, after fights or Zone the enemies off from Objectives.

Late Game

In the Late Game you can legit just flash into the enemy team and deal a **** ton of damage or abuse your insane Ultimate Damage to Zone the enemies off of the Dragon or Baron, Zoning is a really insane tool for Karthus which a lot of people don't think of and is really underrated as you can secure a lot of stuff with that.
