In The Cycle Frontier, you need Textiles to upgrade your backpacks, but you have to find them first.
The Cycle: Frontier – Release Trailer
Every step you take in the regions of Fortuna III in Cycle: Frontier could be your last. There is a chance that you will lose everything you have brought with you when other players try to steal them, or monsters lurking around the area will lead you to your death.
However, you must consistently take risks and upgrade your equipment to advance in the game.
Textiles are among the most important items to collect in The Cycle Frontier, but the game doesn't help you figure out where to look.
