Hello guys! It's MisterFirstBlood from EUW with another ADC guide for you! Today, I want to give you a quick overview and explain all the basic information you need to know about Senna.

Whether Senna is viable as an AD carry or better played as a support highly depends on the current patch. Unfortunately, she is not in a good spot right now. Nonetheless, the provided information might help, and if she gets some balance changes, she might be a solid pick again!

Senna really benefits from initiating short trades, typically using either W, Q and an auto attack or just Q and an auto attack. It doesn't really matter how much health you lose while trading because you can heal up within seconds using your Q ability and Fleet Footwork. This also makes it easier to escape after using your burst rotation since you gain movement speed from your fully charged shot. Presence of Mind helps with your mana problems while laning, while Legend: Alacrity and Cut Down optimize your damage output.

As a secondary tree, I highly recommend Inspiration. Biscuit Delivery further increases your sustain and mana, and Approach Velocity makes it even easier to get closer to your CC'ed enemies to Q-auto attack them.

Seriously, there are tons of item builds you could go for right now, and there is not a lot of data from pros who currently play Senna ADC, so it's really hard to tell what is good and what is not. If you aim for a solid damage crit ratio, then Rapid Firecannon, Infinity Edge, and The Collector seem to be a very solid 3-item start.

I also saw some people building Statikk Shiv into 100% crit builds or buying Kraken Slayer, Trinity Force, and Muramana.

I guess if you really want to, give all of these builds a try and figure out what works and what doesn't, but I'm currently not playing Senna enough to tell exactly what's the best.

Try to trade as much as possible but avoid all-ins. You really need those stacks to scale well into the late game.

While walking to a lane, always check for killed jungle monsters' leftover souls to collect with your passive, especially from drakes, barons, and heralds, which always leave multiple souls behind.

Try to position yourself behind your support/ADC while laning so you can not only poke your opponents or last-hit minions but also apply the heal to your laning partner/teammates.

By using your E ability and giving camouflage to your allies, you can protect them from on-click abilities like Veigar's ultimate if they lose vision on them.

Always pay attention to the whole map and your teammates' icons to be ready if a global ult is needed to protect them or finish off an opponent.

Pros:

🟢 High burst

🟢 Abundant crowd control

🟢 Tons of sustain

🟢 Great scaling into the late game if laning goes well

🟢 Excellent supporting abilities

Cons:

🔴 Not much DPS compared to high attack speed hypercarries

🔴 No dash/jump makes her really vulnerable if an assassin gets close

🔴 Not a lot of damage against tanks

🔴 Needs a good laning phase to get lots of stacks early to be super effective in the late game

P: Absolution 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.

Q: Piercing Darkness
From the twin barrels of her Relic Cannon, Senna fires a unified beam of light and shadow through a target, healing allies and damaging enemies.

W: Last Embrace
Senna sends forth a wave of Black Mist. If it hits an enemy it latches onto them hungrily, rooting them and everything nearby after a brief delay.

E: Curse of the Black Mist
Senna draws the Mist she has stored in her weapon into a storm around her, embracing darkness and becoming a wraith within. Allies who enter the area are camouflaged and also appear as wraiths as the Mist shrouds them. Wraiths gain increased Move Speed, are unselectable, and hide their identities.

R: Dawning Shadow
Senna calls upon the relic stones of fallen Sentinels, splitting her relic cannon into a holy array of shadow and light. She then fires a global beam that shields allies from harm, while damaging enemies caught in the center.

Thanks for paying attention to my guide.
Senna is a unique ADC and support champion with a mix of ranged attacks and supportive abilities. She excels in initiating short trades, healing with her Q ability, and providing crowd control. Her passive allows her to collect souls from defeated enemies and jungle monsters, enhancing her damage and range over time. Senna's ultimate is a global ability that can heal allies and damage enemies. While she has strong burst damage and sustain, she lacks mobility and has a weaker early game compared to other ADCs. Her effectiveness largely depends on collecting stacks and having a successful laning phase.
