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 Blitzcrank
Tips to maximize your impact
- Grab from a clear angle
Fire Rocket Grab (Q) from a brush or a side angle: it grabs the first enemy hit, so you need a line without minions.
- Power Fist right after the grab
After a successful grab, cast Power Fist (E) right away: your next auto knocks the target into the air and deals double damage.
- Sometimes engage without a grab
Sometimes engage without a grab: rush in with Overdrive (W), knock your target into the air with Power Fist (E), and save Rocket Grab (Q) for when they Flash away.
- Bait with your shield
Use Mana Barrier (passive) to bait: at low health you get a shield based on your mana, enough to make a kill look easy.
- Save your grab for their carry
In teamfights, save Rocket Grab (Q) for their carry and wait for them out of vision: grabbing them before the fight starts often decides it.
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.
