How to Craft Trent Axe: Orzeca's Treasure - Black Desert Mobile Guide (2023) 

Thank you :)

For now I believe you can only have one perilla's star. It's a unique item that I don't believe we've ever gotten before. I think it's better than the brilliant glyph if you don't already have a perilla's star. We don't have anything else like this so it's a best in slot :)

It’s just a rare drop from rift. It can be used for the treasure item or if you get another it can be sold to a vendor (I think for 50b)

Thanks you for telling me this i really didn't know now i do so thank you so much for your help
