Cube Hub

The Hero-dric Cube unlocks at level 4 and becomes the center of TBH itemization. Learn function order before Auto Fill burns your build.

Function Map

Default UI opens on Synthesis - switch to Alchemy early. Level the Cube with on-level materials when possible. See Alchemy vs Synthesis for the decision tree.

Crafting fills gaps when drops refuse to cooperate, but it is not a substitute for Alchemy gold during the slot-unlock weeks. Socket systems arrive as rarities climb: decorations around Rare+, engraving Immortal+, inscription Arcana+ depending on your patch tooltips.

Removal is a safety valve, not a junk drawer. Unequip first, understand costs, and never yank sockets mid-listing without checking Trade Ship expectations for clean gear.

Recommended Function Order

Early: Alchemy almost everything that is not a strict upgrade. Mid: selective Synthesis of nine-packs once Cube level can respect item levels. Later: sockets and Removal as you specialize the permanent trio.

Players who live in Synthesis at level 4 starve Rune of Command and wonder why Hunter DLC "does nothing." The Cube is a gold engine first, a rarity engine second, and a socket studio third.

Between sessions, process AFK bags in the same order: lock keepers, Alchemy junk, set aside market candidates, only then fuse duplicates you truly want to climb.

  1. 1

    Lock keepers

    Alt + Left Click before Auto Fill.

  2. 2

    Alchemy junk

    Fund runes and Cube XP.

  3. 3

    Sort market pieces

    Arcana+ candidates go toward Trade Ship, not melt grids.

  4. 4

    Synthesize selectively

    Nine same rarity when Cube level is ready.

  5. 5

    Socket with a plan

    Match roles; unequip before Removal.

Safety Rules

Most "Cube ruined my item" stories are Auto Fill without locks or synthesis below a safe Cube tier. Slow down when rarity jumps. High grades deserve manual clicks.

If you are tired after work, Alchemy locked junk only. Save Synthesis and Inscription for a focused session where you can read every slot.

Leveling the Cube

Community videos emphasize feeding materials near your Cube level band for efficient XP. Dumping absurdly high or low fodder can feel productive while slowing the level that protects future synthesis.

AFK stages that print on-level gear are better Cube XP than occasional lucky uniques you are afraid to touch. Process volume with locks, not fear-hoarding that clogs inventory.

Watch the embedded leveling video on this page for visual pacing, then return to Alchemy vs Synthesis when deciding which piles become gold versus rarity climbs.

Cube vs Market

Alchemy is in-game gold. Trade Ship is Steam wallet economy. Never confuse the two panels when listing Arcana+.

After 1.01.00, higher-grade trading matters again. Melting a listable Immortal for a trickle of gold can be the most expensive click in the game if the Market is healthy.

Use the Market hub for holds, Steam Guard, and mailbox reclaim. Use this Cube hub for craft and fuse literacy. Together they form TBH's real endgame loop.

FAQ

Why did synthesis downgrade my item?
Low Cube synthesis tier can fail downward - level the Cube first.
When do sockets unlock?
Decorations around Rare+, Engraving Immortal+, Inscription Arcana+.
Should I Alchemy or sell early rares?
Usually Alchemy until slots and automation are funded, unless a piece is a strict upgrade.
Is Auto Fill safe?
Only after Alt-locking keepers. Otherwise it is the fastest way to delete a build.
Does Cube XP need premium currency?
No - play, Alchemy, and on-level materials are the core path.
