Interactable, duplication and unlocks

What Does the Microwave Do in Megabonk?

It duplicates one item you select, charges Gold, and consumes another random item of the same rarity. Use it when the extra copy is worth both costs.

SELECT 1 ITEM → RECEIVE 1 EXTRA COPY

Quick Answer

The Microwave is a green-marked map interactable that duplicates the item you choose. Its displayed color determines which rarity it accepts. The trade costs Gold and removes another random item of the same rarity.

Before confirming: count every same-rarity item you can afford to lose. The duplicated item is your choice; the sacrificed item is not.

How the Microwave Works

  1. Find the green marker.
    Placement varies with the generated map.
  2. Match the displayed rarity.
    The machine offers owned items from its current rarity tier.
  3. Select the item to copy.
    This item receives one additional stack.
  4. Review both costs.
    You pay Gold and lose another random item from that rarity.
  5. Accept or leave.
    Skip when every possible sacrifice matters more than the duplicate.

Which Items Should You Duplicate?

Unlock objective

Prioritize Ice Crystal for Noelle or Moldy Cheese for Moldy Gloves and make all three copies consecutively.

Build-defining stack

Choose a stack that changes damage, survival or economy enough to justify both costs.

Skip when every other same-rarity item is essential.

Gold planning

Keep enough Gold for chests and other interactions your run still needs.

Key and Quest Interaction

The inventory Key is not Monke's Gold Key. The Common Key item can make chests free. It does not open Monke's cage.

The Microwave works with inventory Items matching its rarity. Special quest objects are separate interactions.
