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 Lux
Tips to maximize your impact
- Start with Light Binding
Start with Light Binding (Q), then Lucent Singularity (E) and Final Spark (R) before detonating the singularity: the root makes sure everything hits.
- Weave an auto between spells
Slip in an auto after each spell that hits: it triggers Illumination (passive) for extra magic damage, and Final Spark (R) triggers it too.
- Light up brush with your E
Cast Lucent Singularity (E) into a brush before walking in: the area is revealed, and a hidden enemy would be slowed.
- Shield your allies twice
Cast Prismatic Barrier (W) through as many allies as you can: the wand shields them on the way out, then again on the way back.
- Use your R often
Cast Final Spark (R) to clear a wave or secure an objective: it only has a 60 to 40 second cooldown, depending on rank.
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.
