What are the other ways to aquire a without obtaining it from another User?

You would have to buy it from the Blackheart Hollow, which restocks rarely. Items from it are very expensive, and can be purchased with Wizard Tokens. If you go to the Blackheart Hollow too often you could be banned temporarily.

Banned from the Hollow, of course.

Not Subeta.

(Just felt the need to clarify, since I myself am a dumb blond and if I read that and thought I could be banned from Subeta for it, I'd never go there ever lol)
