Playing as Senna

Tips to maximize your impact

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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

  1. 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.

  2. 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.

  3. 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.
