A big part of making the Bel’Veth boss fight easy is surviving the tons of attacks she throws at you.

Bel'Veth is the third boss fight in the League of Legends PvE game mode Swarm. Check out this guide for everything you need to know to beat her and progress in LoL Swarm.

LoL Swarm Bel'Veth boss guide

The Bel'Veth boss fight begins once the timer hits 15:00 on the Subterranean Lab map. No matter where you are in the area, you get sent flying to the left-most section. You must make it to the boss arena on the far right of the map without getting swallowed by the field closing in.

The actual boss fight begins when you enter the arena. Bel'Veth will begin hitting you with two main attacks. Throughout the fight, there will be rubble falling. If you take too long, the rubble will eventually cover the whole arena, and, combined with the ring shrinking, will end your run.

Bel'Veth boss fight attacks

The first one is her dashes - she will dash around the cramped arena hoping to hit you. Avoiding this is simple enough, just move out of the way once the indicators appear.

For her second attack, she will glue herself in the middle of the room and then spawn small spikes from underground. Again, avoid when the indicators appear, but they are quick. Luckily, they don't deal that much damage; the real threat is the small knockup it applies.

Don't let Bel'Veth ult

Sometime during the Bel'Veth boss fight in LoL Swarm, she will spawn four Void Corals in a square pattern. This is not a DPS check and you cannot destroy the Void Corals. You can, however, damage her while she's doing this. She will assimilate each Coral one by one and enter her enhanced state.

Bel'Veth's attacks get stronger when she becomes enhanced. The indicators for her dashes appear one after the other, and then she will dash rapidly, multiple times, turning it into a memory game of sorts.

The enhanced state will wear off eventually, and it doesn't make her any tankier, so you can still beat her in this form.
