The Gold Element badge text is: there is a small chance when using Iron Throw that the cube is golden, and you should not miss it.
Steps
- Unlock Iron from the element list and equip it.
- Enter the arena.
- Use Iron Throw until a cube looks golden.
- Hit another player with that cube.
A March 2026 community badge note says the gold block chance is 1 in 40. Another guide estimates 1 to 5 percent. The catalog does not choose. The attempt planner on the calculator page uses 2.5 percent only as the 1-in-40 figure, and you can change it.
Empty servers are mentioned by players who needed a target for the cube. That is a practical tip, not a catalog rule. If a golden cube hits and the badge does not appear, the hit may not have counted. Try again rather than switching elements.
Gold is a badge element, so it is not a Diamond shop row.
