Senna

Senna can attack souls that spawn from dead enemies to absorb their Mist. She can also siphon Mist from enemy champions she hits with Attacks or Abilities twice, dealing an additional 1% current Health physical damage.

Each stack of Mist grants 0.75 Attack Damage. Every 20 stacks grant 20 Attack Range and 10% Critical Strike Chance but she only has 200% Critical Strike Damage. 35% of excess Critical Strike Chance is converted into Lifesteal.

Senna's Attacks take extra time to fire, deal an additional 10 physical damage, and briefly grant her 10% of the target's Move Speed.

Senna shoots a bolt of piercing shadow through an ally or enemy, dealing 30 physical damage to enemies and Slowing them by 15% for 1 second(s). Restores 40 Health to allied champions.

Attacks reduce this Ability's Cooldown by 1 second.

Senna sends forth the Black Mist, dealing 70 physical damage to the first enemy hit. After a 1 second delay the target and other nearby enemies are Rooted for 1.25 second(s).

Senna dissolves into a cloud of Black Mist for 6 seconds, becoming a Wraith. Allied champions who enter the Mist are Camouflaged and become Wraiths when they leave. Wraiths gain 20% Move Speed, are Unselectable, and hide their identities as long as no enemy champions are nearby.

Senna fires a beam of light that deals 250 physical damage to all enemy champions hit. Allied champions hit in a wider area receive 120 Shield for 3 seconds.
