Cube Synthesis Simulator
Synthesis consumes 9 items of the same grade and rolls the result grade by weight. Low grades always rank up, but Immortal and above carry a retention chance. Odds are taken straight from the game data.

Synthesizing 9 items of the same grade yields a higher-grade item. Pick a grade and hit Synthesize. The result follows the odds shown below — and from Immortal up, it can also stay the same grade (retain).
