Senna lane is a soul-tax game: weave two clean hits to cash Mist — most often Q through a minion, ally, or ward into auto, or auto into Q — and end the trade once you get paid.
Do not let soul greed build your funeral wave: blind autos for stacks create the long lane engage supports want, so keep the wave thin, use brush to drop return damage, and remember early holes punish Senna more like Ashe or Pyke than fallback enchanters.
When the game turns bad, stop forcing the carry version of Senna and rebuild from the edge — safe Mist, W on divers or clean follow-up, E to blur target calls or cover peel, and R early for shield and swing instead of hoarding a snipe; recent data says those behind games recover much better if they stretch.
Into engage, treat every soul like it has a price tag. Your job is to collect only the cheap ones: use Q through the wave, keep the minion line thin enough to back out after the second touch, and stand where their engage has to cross more distance than they want. If Leona, Nautilus, or Rell still have the button that starts the lane, do not walk up just because a soul dropped. Let them spend the first move badly, then answer. Brush matters more here because disappearing after the first hit cuts down the return trade. If the lane gets ugly, stop chasing stacks and preserve HP until the next clean window.
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.
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.
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.
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.
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.
