Honestly i wouldnt join spell casters there's nothing but fluffs and fluff spells in this coven. I mean there might be some good spells. But a lot of them are fake and dont work.
I would try to find a coven on here that your interested in. And if they are accepting new applications or memebers you can apply for that coven. But i know you must be a council member in those covens in order to post new spells.
