Darius, the Deathsinger is one of the most favourite ap carries in League of Legends, who can be very useful in the jungle. Karthus’ passive skill is called Death Defied and it does the following:

“Upon dying, Karthus enters a spirit form that allows him to continue casting spells.”

That’s a great opportunity to get the kill after your champion has fallen, but good players will not let you use this passive effectively.

General Tips

Now that you know the spells, runes, items and which abilities you’ll skill it’s time to learn how to actually jungle on this champion.

Jungle clear:

  • The jungle clear on this champion is it’s a most powerful tool, to do it 100% efficiently you’re gonna have to kite jungle monsters.
  • But it’s more than just spam your abilities on the camps, to be 100% efficient, you must always use 2 Qs and 1 auto, repeat this pattern always in order to clear it as fast as possible.
  • You always start on the blue side and you always full clear, ALWAYS.
  • This takes a bit of practice to achieve, so go to practise tool.
  • You have optimized your clear once you achieve full clear in less than 3 minutes with a leash.

Win conditions:

It’s essential that when you play a champion you understand what will make it win, luckily Karthus has quite a few.

The most important one is to play around objectives, such as drakes/baron.

Due to his high DPS nature, he can bring down objectives really fast in comparison to most champions which really enables your team to simply just rush them if the enemy team is lurking around the map. Fighting in closed locations is also very good since you have AoE damage and can hit multiple opponents in fights.

The second win condition would be to play for sidelanes with your ultimate, or you can do it yourself as well, Karthus is a good duelist, obviously, he’s far from being the best, but he can handle himself vs a couple of champions especially if he’s ahead.

If you find it hard to coordinate with your team to play sidelanes, which sometimes can be very frustrating in slow due to the lack of communication, just group and fight it out, in the end, it’s what Karthus does best.
