Before we get into all the details, check out Senna's champion spotlight:

Senna can attack souls that spawn from dead enemies to absorb their mist. She can also siphon mist from enemy champions she hits twice, dealing [1-16%] of their current health as bonus physical damage (4 second cooldown per target)

Each stack of mist grants 1 Attack Damage. Every 20 stacks of mist grant 25 attack range and 15% Critical Strike Chance. 35% of excess Critical Strike Chance is converted into Lifesteal.

Relic CannonSenna's attacks take extra time to fire, deal [20% AD] bonus physical damage on-hit, and briefly grant her [10-20%] of the target's movement speed.

Senna gains Adaptive Force instead of Ability Power from Spell Thief's Edge and the items it builds into.

Souls are less likely to spawn from enemies Senna kills, but will always spawn from champions and large minions and monsters. Senna does not gain Attack Damage on level up. Her critical strikes deal 35% less damage

% scaling on damage is 1/2/3/4/5/6/8/10/12/14/16 - caps at 16% at level 12

Relic cannon speed is 10% at lv 1, 15% at lv 6, & 20% at lvl 10.

Lore

"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 wraith 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."

"Senna rose to fame with her stunning vocal range and iconic sense of style, but when a shady adversary from her past imprisoned her in a restrictive record deal that took away her creative independence, she vanished from the spotlight. After years of living in the shadows, she now emerges as the lead singer of True Damage with her mind set on defining her legacy on her own terms."
