Rebirth Forge Idle is an idle progression game built around enhancement and reforging. Reforge randomly obtained swords, push through the risk of success, preservation, and destruction, and aim for higher-level blades with rare traits. Combat runs automatically in spectator mode. Turn-based auto battles continue on the side while you keep enhancing, selling, and acquiring new swords to grow stronger. Game Features - Luck-based enhancement loop: costs rise and success rates fall as you enhance. Just one more try! - Random collection: both swords and traits are random, including grade, pool, and duplicate rules. - Enhancement encounter choices: events during enhancement can change traits and stats. - Rebirth reset progression: reset your run through rebirth and spend rebirth points on permanent upgrades. Casual tone and playful flavor text: collect the forge's suspicious excuses and quirky lines. This is not an action game. Instead of fast controls, it focuses on the tension of probability-based enhancement and the thrill of growth when success lands. Step into the forge, overcome the risk about to explode, and complete your own top-grade sword!
