Intoduction
Hi guys, this is my guide to
Karthus jungle. Karthus can be an amazing jungler because of his extremely high clear speed, global presence with his ult, and strong
Predator ganks, a keystone that also gives him bonus damage on his ult.
While a midlane Karthus can be easily abused and quickly become free food for assassins or burst mages, a jungle Karthus is overall a much safer blind pick in any game and can just play reactively on the map in a bad jungle matchup, focusing on fast farm and ganks.
Have a nice read!

Gameplay tips
- Starting red buff is better. You don't need the mana regen from blue buff, you only need HP regen, and most importantly the red buff has magic resist so it's very hard to solo early.
- Always go for a full clear (red->blue side->scuttle typically)
- Karthus is not bad at contesting scuttlecrabs early. Don't expect kills but Q+smite is solid for securing the crab and Q poke is good zoning. You're also very safe since you can just disengage with
Wall of Pain.
- Don't counterjungle aggressively, but always do it reactively when you see the enemy jungler on the other side of the map.
- While he has decent ganking ability, Karthus is still at the core a farming jungler, and his biggest strength is his ability to flashfarm the entire map. Always clear empty lanes whenever you can.
- Time your ultimate right. Either you use it at the start of a fight so you can get assists, or at the end of a fight to pick off low health champions who are fleeing. But avoid using it in the middle of a fight since the enemy champions may die before you get the assist.
- When you die, you have time for 3
Lay Waste casts before your ultimate.
