AP Karthus Tips and Tricks

General
  1. Late in the game, you can sell boots and go for sixth AP item.
  2. You can stop push by using W on minions.
  3. You can die in strategic positions and prevent enemy team from pushing/defending turret.
  4. You can start casting your R when somebody is dead and has 2 seconds left, so you will hit him instantly with R (i.e Fizz won't use E to dodge it).
  5. You can use E before using portal and you will damage enemies when travelling!
Riot
  1. Ask your allies to help point out when you should use Requiem to get kills in different lanes.
  2. Lay Waste is very strong at farming minions and harassing enemy champions.
