Coins at the Upgrade stall buy more ore space, stronger training gains, better Forge luck, or faster movement. Choose the upgrade that helps your next activity, and read each price as the cost of one more level.

What to Upgrade First

  • Your bag fills before you finish collecting: Buy Ore Bag first. Its first level costs 50 Coins, compared with 300 Coins for each of the other upgrades. More carrying room lets you bring back more materials per trip.
  • You are focusing on Power: Buy Training Boost before spending time on training pads. It improves the Power those pads provide. See the training guide for pad selection and Auto Train.
  • You are focusing on forging: Buy Luck Boost to improve Forge luck. Its percentage is a luck bonus, not a guaranteed chance of receiving a particular item. Compare other luck options in the boosts and luck guide.
  • Moving around is slowing you down: Buy Walk Speed for faster movement.

Reassess after each purchase. Once carrying space is comfortable, a boost for your next activity can be more useful than another bag level.

Upgrade Effects, Prices and Level Caps

Ore Bag caps at level 40, Walk Speed at level 10, and both Luck Boost and Training Boost at level 25. Each Boost reaches +50% at its maximum level.

Prices apply to the specified level transition, not every level or the total cost of reaching that level. Prices shown with K use thousands of Coins and retain the menu's rounded precision. A MAX label means that upgrade has reached its cap.

Buy One Level at the Upgrade Stall

  1. Approach the blue-and-white Upgrade stall in the lobby and press E at the Open prompt.
  2. Scroll to the upgrade you want. Read its current level, current effect, next effect, and Coin price.
  3. Click the price button to buy one level. For example, Training Boost level 3 → 4 costs 858 Coins and raises the bonus from 6% to 8%.
  4. Read the updated level and price before buying again. After that purchase, 1.22K Coins buys Training Boost level 5, raising the bonus to 10%.
  5. Close the menu with the red X when finished.

If you cannot afford an upgrade, its button can appear gray. Attempting to buy it can open a Robux cash offer; opening that offer does not grant the upgrade. Close it and save more Coins or sell items you no longer need. The money and selling guide explains how to fund upgrades and decide what to sell.

Ore Bag Bonus Versus Total Capacity

The Ore Bag row displays the extra slots contributed by the upgrade. A preview of +11 → +12 means the next purchase increases that contribution by one slot. It does not mean your entire bag holds 12 ores.

Read the capacity number after the slash in your HUD bag counter for your actual total. In a setup with 16 total slots at Ore Bag level 11, buying level 12 increases the total to 17. Other capacity bonuses can make the same Ore Bag level produce a different total: level 10 can accompany 14 slots in one setup and 15 in another.

Two other capacity sources matter:

  • Index rewards add extra bag slots. The level 3 ROOKIE configuration includes a cumulative +1 slot, while the level 8 COLLECTOR configuration includes +2 slots. See Index rewards for the collection and claiming process.
  • 2x Carry doubles ore carrying capacity. For example, a setup with 8 slots becomes 16 after purchasing the pass. See game pass benefits and prices before choosing a paid capacity upgrade.

When your bag is full, return to town to use ore in forging or sell ore you do not want to keep. Upgrade Ore Bag if capacity repeatedly cuts trips short; use the ore farming guide to plan pickups and filters around the materials you need.
