FAQs About Karthus
What is Karthus' greatest strength?
While many would argue that Karthus' greatest strength is his global Ultimate that can damage everyone, no matter where they are, we'd disagree. We believe his greatest strength is his ability to deal large amounts of AoE damage, even when dead. Karthus can continue to deal damage for a long time, even after his death. Adding Rylai's Crystal Scepter into your Karthus build can slow a large number of enemies and do more DoT. Because Karthus can deal damage even when dead, he's often not the priority of the fight. Killing him won't save them.
What is Karthus' greatest weakness?
Karthus' Q is a powerful, offensive ability with low cooldown. However, it is very skill dependent and can be dodged. Furthermore, its damage increases if only one target is hit. In teamfights and in lane, there are often other nearby enemies that dilute his single target potential. Karthus' only reliable source of damage in the middle of a teamfight is his damage aura. Use your slow to keep enemies close. To reduce the danger of diving into the enemy's back line, include Zhonya's Hourglass in your build for Karthus.
Is Karthus better in lane or in the jungle?
In the current meta, Karthus is best in the jungle. His powerful slow will help him gank while his global Ult allows him to participate in kills anywhere on the Rift. He's not just limited to a single lane or gank opportunity.
