Hello and welcome to my Karthus guide. Karthus isnt a very versatile champion, because as you can see the only way to build him is to stack phantom dancers because all other items suck. I have never played Karthus, but watching other people playing himhas made me rly fking awesome with him.

PROS + CONS-

Ranged Master Yi counters you hard
Good base stats Gay ultimate
Can die without losing downtime Gay

Now you might think that im stupid picking fortify and fortify. Yes, they were actually deleted from the game a while ago, but i use them anyways because they are very good for towerdiving. This is a pro guide after all no ****ty noob wtf lmao dumbass guide for ******s that play bad champions suck as janna and sona.

This is the most important thing in the world. Seriously.

I have seen too many karthus players max their Q ability first. THAT SUCKS. When you look at the spell, it says that it scales with ability power, and what the bloody hell is that? All we use is phantom dancers, and you already do tonns of damage and run rly rly fast so why would you want a ****ty spell when you can use your E to look cool and your W for the ground to look cool.

Your ultimate is gay and only noobs use it so I decided to not put any points in it.
