Cuberarev1.00.26

Synthesis

Cube / Progression

Combine 9 same-rarity items into 1 of the next grade. Output item level comes from a dropdown, not the fodder.

Key attributes

Unlocked: Initial (Hero Level 4)
Order: 2
Total Functions: 8
Recipe Tiers: 8 (Lv 1 → Lv 70)
Enhancement Layers: Decoration, Engraving, Inscription

Notes

Synthesis rolls the next-grade odds below Immortal 100% of the time. From Immortal up the roll can stay the same grade, and a rare great success jumps two grades (★). Always set the output item-level dropdown deliberately — it does not auto-pull from the fodder.
