How it works

  1. You play as Mage building Burn items.
  2. You rush Liandry's Torment.
  3. You burn your enemies. With DOTs. And debuffs.

How to play

  1. Playing AP Burn Karthus build, your default rush is Liandry's Torment vs. HP, Blackfire Torch vs. squishes. Then get the other item
  2. Adapt to an enemy team. Are they full of tanks, and they rush tons of Magic Resist? You rush Void Staff as #2 or #3 item to counter MR stacking. Their team has champs with lots of healing? Rush Oblivion Orb as #2 item (upgrade to Morellonomicon as 4th or 5th item).
  3. Items like Morellonomicon or Oblivon Orb are extra effective with this build, thanks to damage over time effects from Liandry's Torment.
  4. In some rare cases, when an enemy team has an extremely strong shielding, you can even buy Serpent's Fang. It works with your DoTs, meaning shield reduction lasts longer.
  5. They have lots of melee? Or you just want to kite them? Get Rylai's Crystal Scepter.
  6. Somebody is going after you each fight? Always getting ulted by enemy assassins? Rush Zhonya's Hourglass.
  7. If you are doing well, are ahead and want to have some fun, you can buy The Collector item. It works off your damage over time effects!

Tips and Tricks

  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!
  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.
