To buy an item from Blackheart Hollow, do you first need wizard tokens in your inventory? Thanks so much!

I've been able to buy items from BHH with wizard tokens in my currency storage, viewable from your vault here

Wizard Tokens in your Inventory won't work at all. Before it was possible to bank currencies, you did need to have the currency in question (not just WT) in your Inventory, but that hasn't been true for years.

Thank you so much <3

You are welcome
