How Alchemy Works

Alchemy is the Cube's recycling function. You feed it items you don't need, and it converts them into gold. That's it — simple, but it's one of the most important systems in the game.

Unlike selling items through other means, alchemy also grants Cube EXP, making it a dual-purpose operation: you get gold and you level up your Cube at the same time.

Golden rule: Never sell Common or Uncommon items through any other channel. Alchemize them. The gold adds up fast, and the Cube XP compounds over time.
How it fits the economy: Alchemy is your primary gold source for the Rune Tree. Most players find that alchemy gold funds their early-to-mid game progression. The gold-per-item may seem small, but the volume of drops in TBH means it scales dramatically with your farming speed.

Gold Values by Rarity Tier

Higher rarity items yield more gold. Below are approximate values based on community testing:

RarityApprox. Gold YieldNotes
Common3 – 5Small but infinite supply from farming
Uncommon~10Bread and butter — most of your drops
Rare~25Decent value; consider synthesis before alchemizing
Legendary~80Steam Market candidate — check market price first
Immortal~250Rare enough to warrant careful decision-making

Values are approximate and may vary slightly based on item type and level. Arcane and above yield significantly more but are rarely alchemized due to their trade value.

Cube XP from Alchemy

Every alchemy operation grants Cube EXP in addition to gold. The XP scales with the rarity of the item alchemized — higher rarity = more XP.

In the early game, alchemy is often your fastest source of Cube XP. Combined with Offering (which uses commemorative coins for larger XP bursts), it forms the backbone of Cube leveling.

Alchemy Strategy

Always Alchemize

  • All Common items. Their individual gold value is tiny, but you get hundreds per farming session. Alchemize them all — the Cube XP alone makes it worth the 10g cost.
  • All Uncommon items you're not equipping. These are your main gold engine. Alchemize uncommons immediately; don't let them pile up.
  • Duplicate Rares beyond what you need for synthesis. If you have 10+ Rare swords, alchemize the extras rather than hoarding them indefinitely.

Think Twice Before Alchemizing

  • Legendary+ items. Check the Steam Market before alchemizing. Even a mediocre Legendary can sell for far more than the ~80g alchemy yield.
  • Items with good engravings or inscriptions. These carry value beyond their base rarity. Extract the effect first, then decide whether to alchemize the empty item.
  • 9-stack synthesis candidates. If you're close to 9 of the same rarity/type, synthesizing may yield more value than alchemizing the individual pieces.
Pro tip — Alchemy + Rune Tree loop: Farm gear → Alchemize all Common/Uncommon → Gold goes into Rune Tree (hero slots first, then Awakening Rune) → Stronger heroes farm faster → More gear to alchemize. This is the core progression loop for the first 50+ hours of TBH.

Common Mistakes to Avoid

Mistake #1: Selling instead of alchemizing. The sell-to-vendor option exists but yields less gold and gives zero Cube XP. There is almost no situation where selling is better than alchemizing.
Mistake #2: Skipping alchemy to save the 10g cost. The 10g cost per alchemy use is negligible compared to the gold you get back. Even a Common item at 3-5g nearly breaks even — and the Cube XP is pure profit.
Mistake #3: Alchemizing rare materials. Materials like ores, essences, and commemorative coins should not be alchemized. They're used for crafting, offering, and other Cube operations where their value far exceeds their alchemy gold yield.
