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.
MAJOR UPDATE! Made a double statistic guide for beginner karthus and advanced karthus.
Grats to DEWO for this brilliant idea.
Before you are going to read the guide I want to say something. In the end it's all up to you if you choose a karthus with less AP, more survivability or a full AP Karthus. The one to the left is the beginner set-up, the one to the right is the advanced set-up.

One of the best gank tools / debuffs in the game. Set a gank or escape from enemys. This ability makes the difference in teamfights!

Very strong AoE spell. Your late game farming tool as well.
Requiem - Ultimate After channeling for 3 seconds, Karthus deals 250 / 400 / 550 (+70% of ability power) magic damage to all enemy champions (regardless of distance).
cooldown: 180/150/120 seconds The tool to finish off enemys that get away with 10HP. With this skill the line "What a lucker" will be completely banned out of the chat! It is also great to use in teamfights right before initiating. It will be a good start for your team and waiting to use your ultimate might cost you your life.
