Playing as Sion
Tips to maximize your impact
- 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.
- 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.
- 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.
- 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.
- 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
- 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.
- 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.
- 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.
- 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.
- 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.
