Much of the action in League of Legends Swarm mode revolves around endless enemies coming to kill you, which makes Briar’s tanky build all the more fun as she turns against the Primordians.
Briar Build Guide (Weapons/Passives/Augments) | LoL Swarm
In Swarm, Briar is a former Primordian who defects to the Anima Squad halfway through the mode’s story. Once Briar becomes playable, you’ll be able to take advantage of her furious attacks—fast auto attacks, a dual-phase Fish Frenzy/Survival Scream ability, and an Ultimate that helps her escape waves.
Just like in League, the Insatiable Hunger is at her best when she is right up close to the enemy, so survival is of the utmost importance.
This is the best way to build Briar in League's Swarm mode.
