Synthesis

Default

Synthesize 9 items of the same grade into one of a higher grade.

Synthesis combines 9 items of the same grade and category into one item — usually one grade higher. The three categories (Gear, Accessory, Material) are synthesized separately.

Grade-up odds

Result grade per input grade. Below Immortal, synthesis always grades up; from Immortal up it can stay the same grade (a fail).
