Karthus has tons of map pressure when his Ultimate R is up. As long as he keeps an eye on the minimap at all times, he can use it to pick up kills easily.
Even when Karthus dies, he is still a threat to the enemy team thanks to his Passive as he can continue to use his Q and R briefly while he is dead.
Extremely farm oriented champ who can not recover from a set back with ease. If the enemy Jungler keeps invading him, he won’t be able to do much without his team’s help.
His playstyle revolves around power farming till he gets his Ultimate R. This means he won’t be able to gank or counter gank early on unless it is a guaranteed kill for him.
His Ultimate R deals meagre amounts of damage during the early game which forces him to use it only when the enemy is too low. This can be a detriment if he doesn’t have his items or if he is set back early on.

Focus on power farming. You will need to hit level 6 as quickly as possible to unlock your Ultimate R.

Powerfarm in the mid-game. You need to earn as much gold and XP as possible so you can level up quickly.
Try to secure objectives like the Baron and Dragon. Karthus can take objectives fast thanks to his Q and E.

Play around your Ultimate R in the late game. It deals tons of damage and you need for it to be up before committing to a fight.
Stick with your team in the late game. Getting caught out will result in your team having to play 4v5. As you’re the Jungler after all, if you die when the Baron’s up, the enemy will take it for free.
Rush objectives as soon as they spawn. You should be able to take them fast thanks to your Q.
He is powerful whenever he has managed to pick his Blue Buff so that he can spam spells. He has a really quick Jungle clear speed so it should be really easy for him to reach level six quickly.

Fighting the enemy in the Jungle will be very optimal for Karthus due to how his basic abilities work. The enemy will be slowed by his W, while his team and he just kill the enemy team.
His Passive is really helpful during this stage as it completely zones out enemies and prevents them from continuing a fight further. If they do continue, they will just get killed due to how much damage Karthus can dish out when he is dead.
Karthus becomes really powerful during this stage of the game. He can simply just walk up to the enemy team with his E active and end up melting most of the enemy team with ease.
