How it works

General
  1. You use your R frequently, thanks to Axiom Arc cooldown reduction.
  2. You try to use your Rs with First Strike, to boost damage and earn gold.
  3. Liandry's Torment works with Axiom Arc (bigger window of R cooldown reduction because of burn effects).
  4. Last Stand rune does TONS of damage.

How to play

General
  1. Rush #1 Liandry's Torment, #2 Axiom Arc.
  2. You can use R just to poke enemies. 100+ gold First Strike ensured!
  3. Usually wait for First Strike and proc it with your R. Be careful to not get poked, because you waste First Strike procs.
  4. Late in the game, you can sell boots and go for sixth AP item.
  5. The Collector works surprisingly well with DoTs. You can buy it if you are ahead or want to test this out.
Karthus Axiom Arc specific
  1. You will be going in all the time, getting gold, delaing tons of damage, dying and then buying items. This will give you tempo and full build early
  2. Do not be afraid to go in and die. Most of the time, you will reduce cooldown of your R and ult right after.
  3. You max E for sustained damage that works great with your items + R reset + Last Stand rune.
  4. Once you have core items, try ulting on cooldown, ideally targetting whole enemy team. Check for tips section how to do it most efficiently.

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.
