Playing as Sejuani

Tips to maximize your impact

  1. Land both Winter's Wrath swings

    Land both Winter's Wrath (W) swings: the second deals most of the damage and slows, and each one applies a Frost stack.

  2. Permafrost at 4 Frost stacks

    Cast Permafrost (E) as soon as your target has 4 Frost stacks: Winter's Wrath (W) and your melee allies' autos apply them.

  3. Shatter your stunned target

    Hit a target you just stunned: Fury of the North (passive) shatters them for heavy magic damage.

  4. Engage with Arctic Assault

    Engage with Arctic Assault (Q): enemies you pass through take a knock-up, and the charge stops on the first champion hit.

  5. Glacial Prison from a distance

    Cast Glacial Prison (R) at their carry from far enough away: past a quarter of its range, the stun lasts longer and a storm slows nearby enemies.

Playing against Kayn

How to counter and exploit weaknesses

  1. Dodge his Blade's Reach

    Dodge Blade's Reach (W): Umbral Trespass (R) can only target a champion he just damaged, and this ranged hit is how he marks you from range.

  2. Save your CC for his E

    If you have CC, land it during Shadow Step (E): once immobilized, he loses the spell and can't move through walls anymore.

  3. Save your spells for his exit

    Don't cast your spells during Umbral Trespass (R): hidden inside your ally, he's untargetable. Save them for when he bursts out.

  4. Ward your jungle too

    Ward your jungle too, not just the river: Shadow Step (E) lets him go through walls and show up from unexpected paths.

  5. Pressure him before he transforms

    Pressure him before his transformation: until he picks Rhaast or Shadow Assassin, The Darkin Scythe (passive) gives him no healing or bonus damage.
