Senna's abilities
Passive, spells and ultimate
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.

Playing as Yuumi
Tips to maximize your impact
- Steer your Prowling Projectile
While attached to an ally, steer Prowling Projectile (Q) with your mouse before it accelerates: once accelerated, it deals more damage and slows harder.
- Hit a champion to heal
Hit a champion regularly, even with just a Prowling Projectile (Q): Feline Friendship (passive) then heals you, and then the next ally you attach to.
- Make an ally your Best Friend
Stay attached to the same ally most of the time: Feline Friendship (passive) strengthens your bond with them, and your Best Friend empowers your spells while you're on them.
- Stay on your carry
Attach to your carry with You and Me! (W): only towers can target you then, and Zoomies (E) gives them a shield, attack speed and mana.
- Steer your ult onto their group
Cast Final Chapter (R) while attached to steer its waves: each wave that hits slows enemies more and heals your allies.
Playing against Senna
How to counter and exploit weaknesses
- Punish her when she goes for a soul
Take a trade when she steps up for a soul: each bit of Mist she absorbs with Absolution (passive) gives her AD, attack range and crit.
- Spread out if her embrace hits you
If Last Embrace (W) hits you, move away from your allies: after a short delay, you and nearby allies are rooted.
- Target her when she steps up
If you can engage, target her when she steps up for Piercing Darkness (Q): she has no dash to get away.
- Beware the wraiths
Back off when her team disappears into Curse of the Black Mist (E): her allies are camouflaged there, then fast and unselectable.
