Playing as Master Yi
Tips to maximize your impact
- Dodge with Alpha Strike
Cast Alpha Strike (Q) to dodge a spell or a burst: you're untargetable during the strike, and your autos lower its cooldown.
- Meditate to tank damage
Cast Meditate (W) to tank a burst mid-teamfight: you take less damage, heal more at low health, and the time left on Highlander (R) is paused.
- Activate Highlander to chase
Activate Highlander (R) to chase: you gain move speed and attack speed, and slows no longer affect you.
- Chain your kills
Chain kills in teamfights: each takedown lowers the remaining cooldown of your basic spells, and extends Highlander (R) if it's active.
Playing against Karthus
How to counter and exploit weaknesses
- Stay near your minions
Stay near your minions or your allies: Lay Waste (Q) deals much more damage when the blast hits only one enemy.
- Jump on him if you can
If you can engage, jump on him: Karthus has no dash or leap to escape.
- Don't stay low once he hits 6
Once he hits level 6, back instead of staying at low health: Requiem (R) hits every enemy champion wherever they are, 3 seconds after he starts channeling.
- Save your protection for Requiem
If you have a shield, a heal or invulnerability, save it for Requiem (R): it hits every enemy champion 3 seconds after he starts channeling.
- Move away after he dies
Once Karthus is dead, move away: Death Defied (passive) keeps him in spirit form for a while, and he can still cast his spells.
