I just picked up the Re-Roll Aura, but it doesn't tell me how to "spend" it. I went into a shop, hoping to find something to help me undersand, but I still have no idea how it's done.
Honestly I think it might be broken right now I need to double-check. Apologies! There's usually a little circle that you can roll over with a 🔄 emoji above it that you roll over while holding the aura
Just had this too! :)
