Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Hi this is my first build so be patience please and leave comment below about what u think. That's my build for karthus and it works more then well for me. its simply OP.
Well early game u shold go mid. just hold back and spam ur Q as much as u can. his Q is an great range and really powerful skill combined with his W skill which reduces enemy's magic penetration. Your mana early shouldnt be problem because of his passive which gives him mana everytime he kills an unit (even minion). so if u run out of mana just go back to turret and last hit minions. Once you reach lvl 3 or 4 u can rush in for an easy kill. First harras him until he's 1/2 of his health ( which shouldnt be too hard if you're good with aiming your Q spell) then u just flesh in Use ur E then W and spam Q as much as u can and u can also use ignite if he somehow getaway. So he's 99% not able to get away but if he somehow got away u can just use your R for sure. that wont happen in early game probablly but still. U should keep checking your teammates if u can help them out with your R spell While it ain't on cooldown. Karthus is also very important in teamfights while teamfight is running just flesh into middle of fight and use ur E and W and spam Q. Even if u die. U still got ur 8 seconds to spam ur spells (cause of his passive). Also notice that karthus is really squishi champion. He's not good with 1-1. well you're probabbly gonna kill your enemy but you're probably gonna die too. so just be carefull. That's prolly all u need to know.
LAY WASTE - This is gonna be your main skill. It has low Cooldown so spam it as soon as it's available. It'll make tones of damage combined with your W spell as i said already.
Wall of Pain - Its a great skill which slows a target and it also reduces their magic pen if he passes throught. In team fights just throw it in middle of it to hit as many enemies as possible.
DEFILE - Great skill which does lots of damage. U can use it while enemy is trying to run from u . and u just follow him and it'll kill him cause of its range. u can also easily kill whole monion waves. but be careful this skill costs you alot of mana in early game.
REQUIEM - One of most fun spells in game in my options. Its great to use it while someone is trying to run away from u with low health and u just use it and it'll finish him off.
With the build at the end it'll make like 900-1100 damage.
Sorcerer's shoes - Great for its Magic penetration
Rabadon's deathcap - Great for its AP
Archangel's staff (x4) - It gives u an AMAZING AP at the end and it also gives u alot of mana.
At the end with this build u'll have like 1200 AP.
Enjoy it :)
