Cube Guide — All Functions & Unlocks

Every Cube function laid out with unlock levels and in-game screens. You start with Synthesis, Alchemy and Crafting; higher functions and the Lv.10 Trade Ship unlock as you level the Cube.

The Cube is a multi-function tool for converting and upgrading items. You start with three functions; leveling the Cube unlocks higher functions one by one, and at Lv.10 it opens the Trade Ship for trading with other players. Use the table below to get the full picture first.
