Senna combos

Written guide · based on the official ability texts

Harassment

Q AA AA

When: An ally is lined up with the enemy.

Piercing Darkness heals allies and damages the enemies it hits; your cannon attacks benefit from the movement speed bonus.

The root

Q AA AA

When: An enemy is within Mist range.

Last Embrace sends a wave of Mist: if it hits an enemy, they are rooted along with nearby enemies after a short delay.

The global ultimate

When: Your allies are fighting far from you.

Dawning Shadow fires a beam with unlimited range: a shield for the allies hit, damage for the enemies in the center.

Common mistakes

Not collecting the souls: they empower your cannon.
Casting Last Embrace when your team cannot take advantage of the root.
Using the ultimate without aiming for allies or the enemy center.

Official ability descriptions

PassiveAbsolution

When units die near Senna, their souls are periodically trapped by the Black Mist. Senna can attack these souls to free them, absorbing the Mist that held them in death. Mist fuels her Relic Cannon's power with increased Attack Damage, Attack Range, and Critical Strike Chance.

Attacks from Senna's Relic Cannon take longer to fire, deal bonus damage, and briefly grant her a portion of her target's Move Speed.

QPiercing Darkness

From the twin barrels of her Relic Cannon, Senna fires a unified beam of light and shadow through a target, healing allies and damaging enemies.

WLast Embrace

Senna sends forth a wave of Black Mist. If it hits an enemy it latches onto them hungrily, rooting them and everything nearby after a brief delay.

ECurse of the Black Mist

Senna draws the Mist she has stored in her weapon into a storm around her, embracing darkness and becoming a wraith within. Allies who enter the area are camouflaged and also appear as wraiths as the Mist shrouds them. Wraiths gain increased Move Speed, are unselectable, and hide their identities.

RDawning Shadow

Senna calls upon the relic stones of fallen Sentinels, splitting her relic cannon into a holy array of shadow and light. She then fires a global beam that shields allies from harm, while damaging enemies caught in the center.
