CUBE SYSTEM · VERSION-SENSITIVE

Task Bar Hero equipment synthesis guide

Community guides describe synthesis as combining 9 items of the same equipment grade and category to produce an item at least one grade higher. Check the Cube's displayed output range before confirming.

Last source review: 2026-08-11 · The core recipe is cross-sourced; exact output-range rules remain pending verification.

The supported synthesis framework

The collected community guides agree on this working process:

  1. Prepare 9 items.
  2. Keep all inputs at the same equipment grade.
  3. Keep all inputs in the same equipment category.
  4. Read the Cube's displayed output range before confirming.
  5. Expect the result to be at least one grade above the inputs, subject to the current Cube rules.

Check before you consume the items

  • Remove anything that is equipped or reserved for a build.
  • Confirm the input category and grade are consistent.
  • Read the current output range shown by the game rather than relying on an old screenshot.
  • Save the input and result if you are testing an uncertain rule.

Synthesis versus Alchemy

Do not treat the two Cube options as interchangeable. Use the current in-game labels and output preview to decide which operation you are about to confirm. This page covers the synthesis framework only; it does not claim a complete Alchemy formula.

The “five levels lower” claim

Some community material describes an output-range rule involving items up to five levels below the selected target. That exact interpretation and its exceptions have not been verified in the current game version, so it is not presented here as a guaranteed rule.
