I've spent a lot of money at the 7th Witch House over the past 2.5 years -- and of all my purchases, ever, the Frejya Conduit Crown of Sorcery is easily in my top 5.
Frejya's presence is unbelievable. She's a master at magick, period, so she can guide you and accelerate your workings/efforts no matter what you're working on. For example, tonight I had the intention of putting on her crown and doing a Tarot reading with her. I put on her crown, gave an offering and lit a candle for her, and thought I'd knock out a few quick tasks before we got to our Tarot reading. (We're talking 5-10 minutes of busy work, maximum.)
Instead, Frejya has helped me solve something like 5 different problems I wasn't even trying to work on tonight! For every little passing thought that's floated through my brain (i.e. "I should really get to XYZ tomorrow/this week"), she's come up with a stellar solution that I didn't even ASK for!! And we haven't even started Tarot yet, so I can work on the actual problem I wanted to work on with her!!!
Seriously -- get Frejya's crown. Build a relationship with her. Her level of talent and generosity is beyond what I have the words to describe. If there's any piece of advice I wish I could give my younger magickal self, it'd be to build a relationship with Frejya immediately.
Hail Frejya!!! Thank you, thank you, thank you. I so love being your student.
