Game icon Steam Market & Cube System Pitfalls Every TBH Player Must Avoid

Why Cube Stats Get Wiped When You Sell

This is the single most expensive mistake TBH players make — and it happens because the game never warns you. When you list any item on the Steam Community Market, all Cube-attached stats are permanently destroyed. Decorations (gems), Engravings, and Inscriptions — everything you socketed into that item — vanishes with zero compensation.

Example of what this costs you: You spend hours farming a rare +15% Critical Chance gem. You socket it into an Immortal Sword. You decide to sell the sword on the Steam Market. The buyer gets a completely clean sword with no gem. Your rare gem is gone forever. No refund. No warning. No way to undo it.

This rule exists because the Steam Market requires items to be in their base state for trading. The Cube modifications are local to your account — they don't transfer to the buyer. Rather than the game informing you of this before listing, it silently wipes everything.

Which Cube Attachments Get Wiped

  • Decorations (Gems) — Socketed at Cube Level 8, cost 300 Gold to apply. Common, Uncommon, Rare, Legendary gems — all destroyed on listing.
  • Engravings — Applied at Cube Level 15, cost 1,000 Gold. Guaranteed stat bonuses. Permanently lost when the item is listed.
  • Inscriptions — Applied at Cube Level 25, cost 10,000 Gold. Random stat scrolls. Also destroyed.

How to Sell Safely Without Losing Your Upgrades

The safe workflow is simple — decide sell vs keep before you socket anything. Once a gem or engraving goes into an item, you cannot get it back. Here's the correct decision tree:

  1. Identify the item's destiny. Is this a long-term piece you'll use for weeks, or something you'll outgrow in a few stages? Be honest — most early-game gear is temporary.
  2. If you plan to sell: Do not decorate, engrave, or inscribe it. Keep it in its base state. A clean Legendary or Immortal item sells just fine — buyer wants the base stats to customize themselves.
  3. If you already socketed and changed your mind: Use the Cube's Extraction feature (unlocked at Cube Level 10, costs 1,000 Gold per use) to strip all attachments. The materials are still lost, but at least you're not giving a free gem to a random buyer. Then list the clean item.
Build this habit: Every item you pick up, immediately decide: "Keep and upgrade" or "Sell as-is." Put keepers in a separate bag tab or mentally tag them. Never socket first and decide later.

Canceled Listings Go to Your Mailbox, Not Your Inventory

This is the second most common panic moment. If you cancel a Steam Market listing, the item does not go back to your regular inventory. It goes to your in-game Mailbox inside the Cube interface.

How to retrieve canceled items:

  1. Open the Cube
  2. Go to the Mailbox tab
  3. Wait 10 seconds for the refresh timer
  4. Manually claim each item

Players who don't know this will frantically search their inventory, assume the item is bugged or lost, and potentially waste support tickets on items that are sitting safely in their mailbox.

Items You Can Never Sell

Not everything that drops can be listed on the Steam Market. Upgrading an untradeable item is throwing resources into a black hole.

Untradeable CategoryHow to IdentifyWhy It's Blocked
Milestone-Level GearItem level is 25, 35, 45, 55, 60, 70, 75, 85, or 90These are progression-gated items tied to specific stage milestones. The game locks them to prevent market flooding at progression thresholds.
"Type B" Variant GearName contains "Type B" suffixAlternate-version items that the economy system blocks from trading. Functionally identical to normal versions but market-banned.
Common / Uncommon / Rare GearWhite, Green, or Blue name colorOnly Legendary (Gold) and above can be listed on the Steam Market. This restriction was added to combat bot flooding.
Good news — Materials are exempt: Decoration gems, engraving materials, inscription scrolls, crafting ores, and commemorative coins can be freely traded at any rarity. Materials bypass the Legendary-only restriction entirely, making them the most reliable trading category in the current version.

Why Buy Orders Matter More Than Listing Prices

New sellers instinctively look at the lowest listing price and price slightly below it. This works but it's slow — you're waiting for someone to find your listing among hundreds. The smarter approach: check active Buy Orders first.

Buy Orders show you what other players are actively waiting to buy, right now, at a specific price. Matching a Buy Order sells your item instantly — no waiting days for someone to stumble across your listing.

The Complete Pre-Listing Safety Checklist

Before clicking that list button, confirm all five of these. Every point you skip is a potential loss:

  1. Cube Level ≥ 10? No = market access locked. Keep alchemizing.
  2. Item level is NOT 25/35/45/55/60/70/75/85/90? Yes = milestone gear, cannot sell.
  3. Item name does NOT contain "Type B"? Contains Type B = cannot sell.
  4. Rarity is Legendary or above? (Or it's a material — any rarity OK.)
  5. All Cube attachments stripped via Extraction? Or item was never decorated/engraved/inscribed.
Golden rule: Never socket anything into gear you might sell. Decide first, upgrade second. The 1,000 Gold Extraction fee is a tax on indecision.
