Abilities & tips
Open an ability to read its effect and a practical use tip.
PAbsolution
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.
Practise the hit area and target conditions first. Do not spend the rest of your rotation automatically when the opening damage misses.
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.
Read the effect and its conditions, then practise it alone. Build your sequence around the effect you can reliably reproduce.
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.
Use this control to create a follow-up window. Check the target’s defensive spells and your teammates’ range before committing.
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.
Read the effect and its conditions, then practise it alone. Build your sequence around the effect you can reliably reproduce.
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.
Match the protective effect to the moment damage arrives. Read who it protects and how long it lasts before relying on it.

Game plan by role
Senna · Support
Stand where you can help your lane partner without exposing both of you. Coordinate the opening before spending your main control or protection.
Set up vision with nearby allies rather than walking into unlit areas alone. Roam when your lane partner can safely handle the next wave.
Choose between creating an opening and protecting the teammate who can carry the fight. Do not spend every defensive spell on the first visible enemy.
Before your next fight, check: Piercing Darkness · Dawning Shadow · Combos
06
Matchup preparation
Compare opponents in the build for the role you are actually playing. Then check their key control, escape and defensive spells before choosing your trade.
07
Practice checklist
- Cast each ability alone and identify its range, target conditions and stopping point.
- Practise the first sequence slowly. Repeat it while moving, without skipping the conditions shown on its card.
- After each attempt, identify the spell you would still have available to defend or retreat.
