B100X - Auto Dungeon RPG frames its adventure around the Eternal Cave, a monster-filled place that threatens the world. You take the role of a witness assisting Holly, an apostle of God, and venture into the cave amid questions about demons, God’s purpose, and the relationship between Holly’s apostles and humanity. That story gives the dungeon runs a larger mythic backdrop rather than presenting them as isolated fights.
Its defining choice is to make combat fully automatic while leaving players decisions about progression. The game describes an “Anything Synthesis System” alongside automatic battles: use experience, junk, and dropped items to strengthen Holly, then choose a dungeon and target floor for the next adventure. An automatic lap function also supports playing while matched in competitive games, so the format is designed for intermittent attention as well as dungeon progression.
Its appeal, as described, lies in letting the cave expedition continue through automated battles while players shape Holly’s growth and decide how deep to push.
