Karthus·Mid Counters

If you see Karthus channelling his R, try to cancel it with any CC abilities. This will reduce his and his allies chances of getting kills.

Karthus will be looking to farm as much as possible early so he can unlock his Ultimate {{championSpells.KarthusFallenOne}. Try to put him behind by playing aggressive and requesting ganks.

As soon as Karthus hits level 6, communicate with your team so they know he can impact fights with his Ultimate R. Ping as soon as he is level 6.

If you see Karthus using his Ultimate R at the start of the fight, try to CC him so it cancels his Ultimate R.

If you kill Karthus at the start of the fight, try to reposition and get away from his Passive. This will reduce his damage output and make surviving the team fight easier.

If you spot Karthus in a side lane split pushing, you could start a team fight. But, you need to keep in mind that he can influence the existing fight with his Ultimate R.

Once Karthus has his Ultimate R, he can impact the map regardless of his positioning. Whenever you’re fighting the enemy, always take into consideration that he may use his Ultimate R to finish you off.

The more AP and the more magic penetration Karthus gets, the better and stronger he will be. Try to shut him down or constantly invade him to reduce his gold income.

The longer the game goes, the stronger Karthus is going to become. Ensure you put him behind in the early game to make him less useful as the game goes along.
