Playing as Gragas

Tips to maximize your impact

  1. Let your barrel charge

    Let Barrel Roll (Q) charge before detonating it: damage and slow grow the longer it sits on the ground, and if you don't recast it, it explodes on its own.

  2. Drink before you engage

    Drink Drunken Rage (W) before engaging: drinking takes 1 second, then you take less damage and your next auto hits every nearby enemy.

  3. Charge through a clear path

    Engage with Body Slam (E) through a path without minions: you stop on the first enemy you meet, and hitting reduces its cooldown.

  4. Send them toward your team

    After Body Slam (E), cast Explosive Cask (R) behind your target: the blast knocks enemies away from the impact, sending them toward your team.

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.
