Counter Information

1/5

When Karthus dies, step away from his corpse - his passive means he can continue to damage you.

Standing near minions can help reduce the damage output of Karthus' Lay Waste, which does more damage to single targets.

Be aware and ready for Karthus' ultimate as it often catches players off-guard.

Spell shields and temporary invulnerability items may provide easy ways to deal with Karthus's ultimate.

As Karthus is dependent on AP, building magic resistance may prove effective.
