Karthus the Deathsinger
The harbinger of oblivion, Karthus is an undying spirit whose haunting songs are a prelude to the horror of his nightmarish appearance.

Karthus Tips

- Karthus has less crowd control than most champions. This can make locking down kills or ganking for other players more difficult.
- Karthus secures less objectives than most champions. Your value may be better oriented towards helping other champions secure objectives.
- Karthus has a much higher late game win rate than their early game win rate. Take advantage of this by spending the early game farming and avoiding unneccessary fights.
- Karthus has a low base attack speed, which can make last hitting in the early game more challenging. It can also make percentage attack speed items scale less effectively than they do on other champions.
