Playing as Sion

Tips to maximize your impact

  1. Last-hit everything for max health

    Last-hit minions and monsters for Soul Furnace (W): each kill permanently gives you max health, more on champions, large minions and large monsters.

  2. Slow before your Smash

    Slow your target with Roar of the Slayer (E) before charging Decimating Smash (Q): they're less likely to get out of the area.

  3. Charge your Smash for at least 1 second

    Charge Decimating Smash (Q) for at least 1 second: below that, the hit only slows, and beyond it, the knock-up and stun last longer the more you charge.

  4. Keep hitting after you die

    After you die, hit the nearest champion: during Glory in Death (passive), your autos are much faster, heal you and deal damage based on their max health.

  5. Engage or roam from far away

    Cast Unstoppable Onslaught (R) from far away to engage or roam: unstoppable for 8 seconds, you stun longer and hit harder after a long charge.

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.
