Playing as Sivir

Tips to maximize your impact

  1. Hit going out and coming back

    Position so Boomerang Blade (Q) hits on the way out and on the way back: it damages every enemy it passes through, but less after hitting a minion.

  2. Ricochet right after an auto

    Cast Ricochet (W) right after an auto: it resets your auto immediately, and the next ones bounce to nearby enemies.

  3. Save your shield for their CC

    Save Spell Shield (E) for the stun or root aimed at you: it blocks the next enemy ability, and heals and speeds you up if it blocks.

  4. On The Hunt to engage or escape

    Cast On The Hunt (R) to engage or escape as a group: nearby allies gain move speed, and your autos on champions reduce your cooldowns.

Playing against Karthus

How to counter and exploit weaknesses

  1. 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.

  2. Jump on him if you can

    If you can engage, jump on him: Karthus has no dash or leap to escape.

  3. 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.

  4. 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.

  5. 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.
