Vivid World is a party-building roguelike auto-battler built around characters transformed into jewels. Its premise sets up a distinctive kind of dungeon run: players assemble a team from these jewel characters, strengthen their bonds, and encounter the mysteries of the Underworld as they conquer dungeons. The cast also draws on Vivid Knight, with characters redesigned for this new world.
Preparation blends party synergy with resource decisions. Gathering several matching jewels lets players enhance them and build buffs, while equipping Orbs gives each party member another way to shape the lineup. Jewels can also be bought and sold, or merged to strengthen one, making party growth a matter of choosing where to direct resources. These systems give the game a deeper team-building emphasis than a simple roster of fixed fighters.
Combat advances automatically, but players still intervene with Gems during battle phases. Gems can be combined or used individually, so the format pairs hands-off battle progression with decisions about when and how to support the party.
