Playing as Senna
Tips to maximize your impact
- Collect every soul
Attack the souls held by the Mist whenever you can: each soul freed with Absolution (passive) increases your AD, attack range and crit chance.
- One beam to heal and damage
Fire Piercing Darkness (Q) through an ally or an enemy to hit both: the beam heals your allies, and damages and slows enemies in the line.
- Last Embrace on a slowed target
Cast Last Embrace (W) on a target that's already slowed or immobilized: after a short delay, they and nearby enemies are rooted.
- Hide your team in the Mist
Cast Curse of the Black Mist (E) to engage or escape with your team: allies who enter it are camouflaged, then fast and unselectable.
- Save an ally across the map
Cast Dawning Shadow (R) to save an ally across the map: the beam has unlimited range and shields allies.
Playing against Kai'Sa
How to counter and exploit weaknesses
- Stay near your minions
Stay near your minions: Icathian Rain (Q) splits its missiles between nearby enemies, and on your own, you take them all.
- Harass her before she evolves
If your attack range beats her 525 units, harass her early: Second Skin (passive) only evolves her spells as she buys items.
- Dodge her Void Seeker
Dodge Void Seeker (W): it marks you with Plasma and reveals you, which lets Killer Instinct (R) dash onto you from very far away.
