Of the various champions you can choose from in League of Legends' Swarm, Riven can be one of the most fun options at your disposal, but only if you give her the right tools to succeed.
RIVEN S-Tier build in SWARM ANIMA LOADED | League of Legends PVE game mode
Riven is one of the original members of the Anima Squad, an elite group of champions whose sole purpose is to protect humanity’s last bastion from the incoming Primordian threat. However, she jumps into the action alongside a whole new cast of additions as they battle massive bosses and limitless waves of enemies.
For those who want to return to the glorious battlefield, this is the best Riven build in League's Swarm game mode.
Since Riven has a lot of movement at her disposal with her Bunny Hop and Valor Dash, she thrives on a movement speed and damage build to avoid getting surrounded while still dishing out some punishment to enemies around her. She's great at distraction, as she can escape many types of situations while her team regroups, but she can also be a formidable threat when her team needs some durability and damage.
