League of Legends S12: Senna ADC Build Guide

From runes to items, gameplay tips amd more, we've put together a guide to help you master playing Senna in the botlane in League of Legends.

Be mindful that there are several ways to build and play a champion, and you'll need to be adaptable as the game and the enemy team progress.

That said, this guide is a good starting point to helping you get to grips with the champion and making an impact in your games.

Runes

Core Items

Kraken Slayer

3400 Gold

Rapid Firecannon

2500 Gold

Build

Kraken Slayer will shred through even the hardiest of tanks, a useful benefit for Senna.

Rapid Firecannon grants great range on top of Senna's already impressive range, for low-risk aggression.

Other great items include Guinsoo's Rageblade, Manamune, and Axiom Arc.

Starting Item & Boots

Health Potion

50 Gold

Doran's Blade

450 Gold

Boots of Swiftness

900 Gold

Skill Order

While your choices may differ according to how the game progresses, the typical Senna skill priority is:

R > Q > W > E

Summoner Spells

These are the summoner spells most typically taken by Senna in this role. Naturally, this may change depending on match-ups.

Gameplay

Similar to the way Veigar depends on stacks, the key to playing Senna as an ADC is farming up the souls that drop, otherwise you'll find it a struggle to get going later on in the game. You have exceptional range and poke, so use it to your advantage. 

• Level 1 - Take Q - Piercing Darkness, for the poke and early heal.
• Level 2 - Take W - Last Embrace, for the root potential in lane.
• First Back - Aim for your boots, which will help alleviate Senna's slow move speed early on.

Tips & Tricks

• Senna's passive has no hard limit. You could theoretically hit 1000 AD, and if you pass the 100% crit chance threshold this bonus will become lifesteal.
• Piercing Darkness can target wards, allied champions, and enemy turrets.
• Piercing Darkness also resets Senna's auto-attack.
• The range of Piercing Darkness increases according to Senna's auto-attack range, hence going for Rapid Firecannon.
• Curse of the Black Mist makes your allies invisible, making it a great tool for ganking lanes or confusing enemy ranks in a teamfight.
• Dawning Shadow inflicts damage only on enemies in the middle of the beam.
