Rainbonite is a rare ore that only spawns in caves from 1000m - 1999m depth, and is only found in caves. It is required for higher shop upgrades.
- Rainbonite and Topaz are the only ores that spawn exclusively in caves.
- Once your Marketplace is level 7, you should sell some of your Rainbonite or Painite, Dragonglass or Azure. These specific ores are usually very valuable for sale.
- Rainbonite is also good for trading with robloxians or friends for other items.
