League of Legends Swarm Rek’Sai boss guide: How to beat Rek’Sai

The League of Legends PvE game mode is almost here! The first boss you'll face is Rek'Sai - check out this guide for tips on how to beat Rek'Sai in League of Legends Swarm.

First, you have to meet Rek'Sai in League of Legends Swarm. Her boss fight will trigger once you reach 15 minutes on the Warehouse District map. You will be moved into a small arena with Rek'Sai.

On Story Mode (the easiest difficulty) she has 272,000 HP. By this point, you should be loaded up on Weapons and Passives. Ideally, you would also have evolved weapons. Beating her is dependent on the strength and effectiveness of your weapons and passives, along with the upgrades you have.

During the Rek'Sai boss fight, she will occasionally burrow underground. This will leave behind a tunnel that you can destroy. Destroying these tunnels before she unburrows is key to beating her. When done successfully, you will deal a significant chunk (~20%) of her HP. Do this enough times and this boss fight is a breeze.

This is a pure DPS check. If you are having trouble destroying her tunnels, you're probably going to have a difficult time beating her.

She has two big attacks: one single-target and one AoE.

She will mark one character (this will look similar to a Nautilus R, for you League of Legends players) and will charge toward them after channeling. This is considered a dash. so Yasuo's Wind Wall can stop it. Other ways to mitigate or prevent the damage include shielding (Leona, Seraphine) and Invulnerable (Yasuo, Aurora). She does this move if she finishes her burrow with her tunnel still intact.

For her AoE attack, Rek'Sai will rain down rocks during her boss fight. This is also a DPS check; the longer the boss fight goes the more rocks Rek'Sai throws. The first few times she does this, you can easily move your champion to dodge. If the fight takes long enough, the danger zones take over the whole arena and will most likely kill you.
