Karthus counter tips

Laning Against

Karthus will be looking to farm as much as possible early so he can get his power spike and his KarthusFallenOne. Try to invade him to delay his level 6.
Once Karthus has level 6, he will keep an eye on his the map and use his KarthusFallenOne to help his allies. Always keep this in mind as he can impact team fights from afar.
Karthus dueling potential is poor if he is low on mana. Try to find him and fight him if you have strong skirmishing and pick power.

Strategy VS

Due to Kathus’ Passive, fighting in a tight area like around the Baron or Dragon will allow him to deal a lot of damage even after his death. If you kill him in an enclosed area, get out of his Passive so you do not take extra damage.
Do not take any team fights inside the jungle as you will allow Karthus to hit everybody with his kit. Try to limit any team fights in these situations- or atleast kite away from him to reduce his damage output.
Karthus’ KarthusFallenOne is a channel. If you can cancel it, you will stop him from dealing damage to all of your allies. You can cancel it by applying CC or killing him.

Power Spikes

Karthus’ main power spike early is once he has his KarthusFallenOne. When he reaches 6, he will start to gain global map pressure because his KarthusFallenOne can impact several lanes at once. Always take into consideration his damage whentrading- regardless of his location.
Deathcap increases Karthus KarthusFallenOne damage by a substantial amount. Look to interrupt his Ultimate if possible so he can't dish out a lot of damage onto the carries.
Another power spike for Karthus is once he gets Sorcerer Shoes. Once he has those Boots, his abilities will deal more damage and he will be able to trade more effectively. Build items that provide health and magic resist to counter this.
