League of Legends Senna Guide: Best Build, Runes & Combos

Senna is a powerful hybrid support and marksman in League of Legends who excels at dealing damage while providing utility to her team. Whether you’re poking enemies from afar or saving allies with clutch heals and shields, Senna offers incredible versatility in both solo queue and competitive play. In this guide, we’ll break down the best build, runes, items, and combos to help you get the most out of Senna’s unique kit and carry games from the support or ADC role.

Senna Abilities Overview In League of Legends

Passive – Absolution:
Senna can absorb Mist from enemy champions she hits twice with attacks or abilities, and from souls that spawn from dead enemies. Each stack of Mist grants bonus attack damage and critical strike chance, while also extending her attack range over time.

Q – Piercing Darkness:
Senna fires a beam through a target, healing allies and damaging enemies it passes through. It scales with both attack damage and healing power, making it useful for both poke and sustain.

W – Last Embrace:
Senna sends out a shadow that latches onto the first enemy hit. After a short delay, it detonates, damaging and rooting the target and nearby enemies.

E – Curse of the Black Mist:
Senna shrouds herself and nearby allies in mist, turning them into wraiths. While camouflaged, allies gain bonus movement speed and cannot be directly targeted until they exit the mist or attack.

R – Dawning Shadow:
Senna channels a global beam of light that shields allies in a wide line and damages enemies in the center. It can turn the tide of teamfights across the map when used wisely.

How To Play Senna In League of Legends

Best Summoner Spells For Senna

The best summoner spells for Senna are Flash and Heal when playing her as a support or ADC. Flash is essential for positioning, escaping, or making clutch plays with your root or ultimate. Heal is great for keeping both you and your lane partner alive during trades or all-ins. If you’re playing Senna as a support and your ADC already has Heal, consider taking Exhaust instead to shut down assassins or burst champs.

Best Runes For Senna

The best runes for Senna are from the Inspiration tree with a secondary in Precision. Take Glacial Augment as your keystone for amazing crowd control in fights, especially when paired with slows from your passive and Q. Follow it with Magical Footwear, Biscuit Delivery, and Approach Velocity to boost sustain and mobility. In the Precision tree, choose Presence of Mind and Legend: Alacrity for mana sustain and better attack speed scaling. For shards, go with Attack Speed, Adaptive Force, and either Armor or Magic Resist depending on lane matchup. This setup gives Senna great poke, utility, and scaling.

Best Build For Senna

The best build for Senna in League of Legends typically starts with Umbral Glaive for early vision control and poke damage. Follow it with Eclipse or Kraken Slayer depending on whether you want more sustain or raw DPS. Then go for Rapid Firecannon to increase your poke range, making it easier to land roots and auto attacks. Mortal Reminder is a solid choice for anti-heal and armor penetration. Finish with Guardian Angel or Edge of Night for survivability. Boots-wise, go with Boots of Swiftness or Plated Steelcaps depending on enemy team comp. This build gives you solid poke, utility, and scaling in both ADC and support roles.

Best Combos To Learn For Senna

The best combos to learn for Senna focus on maximizing poke, utility, and crowd control. Start with a simple Auto Attack into Q (Piercing Darkness) to deal solid damage while healing allies nearby. For more aggressive trades, use W (Last Embrace) to mark the enemy, follow it with an auto attack to trigger your passive, then hit them with Q to sustain and extend the trade. A more advanced combo is starting Q and then Flashing mid-animation to reposition and catch enemies by surprise, great for unexpected heals or snipes. In teamfights, lead with your ultimate (Dawning Shadow) to shield allies and damage enemies, then follow up with W or Q to lock down key targets. During extended fights, weave Auto → Q → Auto to maximize damage output while continuously stacking your passive. These combos make Senna an annoying laner and a clutch playmaker in fights.

With the right build, runes, and combos, she can carry games through clutch plays and consistent pressure. Whether you’re playing her in the bot lane or as a support, mastering her abilities and playstyle can make a big impact on your team’s success.
