The Cube system explained

All 8 Cube functions, the Cube Level they unlock at, and when to use each — verified against the game data.

QUICK GUIDE
  • The Cube has 8 functions. Synthesis and Alchemy are free from Cube Lv 1; the rest unlock as you level the Cube.
  • Cube Level is separate from your hero level — you raise it by feeding items into Synthesis.
  • Synthesis = random tier upgrade. Crafting = deterministic recipe. Alchemy = gear → gold.
  • Save Inscription for endgame: it costs 10,000 gold per recipe slot and only opens at Cube Lv 25.

The 8 Cube functions and their unlock Cube Levels

  • Cube Lv 1 — Synthesis (free, default unlocked)
  • Cube Lv 1 — Alchemy (10 gold to unlock)
  • Cube Lv 5 — Crafting (100 gold)
  • Cube Lv 8 — Decoration (300 gold)
  • Cube Lv 10 — Extraction (1,000 gold)
  • Cube Lv 15 — Engraving (1,000 gold)
  • Cube Lv 20 — Offering (3,000 gold)
  • Cube Lv 25 — Inscription (10,000 gold)

When to use each

Feed 5 items in, get 1 random output at the same tier or higher. Use it constantly in the early game — it's the cheapest way to level up gear and the Cube itself.

Convert junk gear into gold. Run it on commons and uncommons that don't fit your build. Don't alchemize anything with a stat mod you might want to extract later.

Deterministic. You spend materials and get the exact gear piece the recipe names. Use it when you need a specific stat baseline that Synthesis won't reliably produce.

Adds cosmetic gem slots to gear pieces. Purely visual — no combat stats — but the slots persist when you upgrade the piece.

Pulls a stat mod off a piece you're about to discard. Cost scales with mod tier. Useful for migrating a +Drop Chance or +Crit roll between accessories.

Permanently inscribes a stat line onto a piece. Much more reliable than re-rolling — once it's engraved, it stays through every subsequent upgrade.

Trades a stack of materials for a guaranteed item from a curated pool. Best gold-to-result ratio in the late game; see the Offering page for the per-tier pools.

Applies a best-in-slot mod from your stash onto a piece. Endgame finisher — 10,000 gold per recipe slot, so save it for your final BiS.
