How to play

  1. You rush Heartsteel.
  2. After Heartsteel, you can rush Titanic Hydra (more fun, damage and some survi) AND/OR Sundered Sky or just go full tank - depending on if you are behind and if your team needs more damage.
  3. Sundered Sky is very good damage item for this build. It scales off your HP (so Grasp, Heartsteel, Overgrowth). It gives damage and pretty good sustain in fights. Remember to switch targets to maximize the effect!
  4. This is auto attack oriented Karthus build, so do it! Especially if running with Titanic Hydra and Sundered Sky as well.
  5. Guardian's Horn is a surprisingly good item for its price. You can keep it for a very long time (or even have it as 6th item).
  6. Triumph is better (heal + gold), but if you want to have easier time with your mana, go Presence of the Mind.
  7. You need to adapt your items to the game. Enemy team heavy on AP? Buy MR. They heavy on AD? Buy Armor. You need some damage? Well buy that.
  8. Remember to consume your Heartsteel procs!
  9. Remember to consume your Grasp of the Undying procs!

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 an 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. Enemies in your base? Use E before taking portal (frost-gate) - you will damage them on your way!
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.
