Patch 26.20 · Stats from the 26.18 Master+ sample (3,887 games).
Senna, the Redeemer, collects Mist from fallen units to grow stronger, and Dawning Shadow fires a global beam that shields allies. Counted Master+ Sennas were supports on Deathfire Touch more than Fleet Footwork, building Black Cleaver into Statikk Shiv. Nautilus, Alistar and Rakan were her toughest lanes. She won most of her games against Lulu and Soraka. Thresh, Leona and Pyke were near-even.

How Senna performs against enemy support laners
Recommended items by enemy team composition
SennaSupport average
102030
102030
102030
Track the roam — it is strongest where the enemy jungler already is
Close the gap early — it wins at range and at three items — neither before ten minutes
Punish the cooldown — Senna is exposed while its rotation is down
Ward the flank — vision is what turns its best opening into a worse one
Respect the spike — Riot rates the kit 7/10, so a practised player gets more out of it than the average
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.

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.

Riot's notes from patch 25.S1.1 to 26.20 change Senna in 7 patches. The latest is patch 26.14, published 2026-07-14.
PAbsolution
QPiercing Darkness
Even after her nerfs last patch, Senna is still tearing through the darkness and the light. We're focusing on bringing down her passive and scaling power as she collects souls and takes names, which should impact her in support less, and more in bot where Shiv is rushed for AP ratios.
PAbsolution
QPiercing Darkness
Senna players have moved over to a much stronger Bot lane farming pattern, so we're softening her farming and Shiv synergy while also tuning her DPS around having access to more souls. The Doran's Helm nerf should do the rest of the work necessary to get her to the right power level between roles.
QPiercing Darkness
WLast Embrace
Senna has found herself in a weird state where she can be quite powerful, but not when playing her more popular offense-focused builds. So we're shifting some power around with the goal of maintaining her viable supportive playstyles but making damage-focused builds much better.
Base Stats
Like Jhin, Yasuo, and Yone, Senna's guaranteed critical strikes cannot sustain a 2x modifier, so we're lowering her base crit damage down to a value similar to last year.
Base Stats
QPiercing Darkness
Senna is currently underperforming as a bot laner and even more so as a support. We're giving back some of the attack speed growth she's had previously to improve the feel of her attacking builds, and she's getting a small bump in her Q's base healing.
PAbsolution
As it turns out, the biggest buff ADC Senna received back in 15.10 was players collectively building Statikk Shiv. Now that players are doing that, she no longer needs many of the ADC-specific buffs from last month. So we’re bringing her ADC-specific buffs back down to see how the dust settles with this new tuning.
PAbsolution
QPiercing Darkness
Though it's her more popular build, Senna's AD builds significantly underperform compared to her enchanter setups. We'd like to retain both of these builds as equally viable, so we're buffing her AD builds by giving her better sustained damage output through soul crit chance. We'd also like to significantly raise the viability of carry Senna, so we're giving a large boost to her soul drop rate when last-hitting. As these would buff all builds to some degree, we're slightly bringing down one of her AP ratios as compensation.
Riot's data lists 12 looks for Senna with their own art, the base skin included and 68 chroma variants.

Riot Data Dragon 16.20.1. Growth curve: League of Legends Wiki — Champion statistic.
Senna, the Redeemer, is a Support and Marksman champion in League of Legends. Riot rates the kit 7/10 for difficulty, 7/10 for attack, 2/10 for defense and 6/10 for magic. Senna spends Mana and has 12 skins with their own art. Senna's base health of 530 is the 3rd-lowest of 173 champions on patch 26.20. Senna's attack range of 600 is the 3rd-highest of 173 champions on patch 26.20 (shared with 2 others).
Cursed from childhood to be haunted by the supernatural Black Mist, Senna joined a sacred order known as the Sentinels of Light, and fiercely fought back—only to be killed, her soul imprisoned in a lantern by the cruel specter Thresh. But refusing to lose hope, within the lantern Senna learned to use the Mist, and reemerged to new life, forever changed. Now wielding darkness along with light, Senna seeks to end the Black Mist by turning it against itself—with every blast of her relic weapon, redeeming the souls lost within.
