What do you build on karthus

Its still mandatory. Its just also very sad

Nothing, you sit there and play the waiting game for when and if they'll buff him.

you don't need it

i like getting if I'm carrying

swap morello for abyssal or Zhonya if you need either of them

I normally don't build it on him anymore, but I still have it as a situational set up if you want to pair it with and maybe.

My usual build: Either OR

How you build depends on how the match is going, certain champs/Matchups, etc however, so you may need to adjust.

I normally don't get boots unless I'm going for a Full Magic Pen build (usually ), mostly because in most cases Movespeed isn't quite as important to Karthus as people think.
