If you’re a Professor, you can complete Fortress Challenges without using a single bolt of Spell Energy.

You can even help out your Auror and Magizoologist friends to save their spell energy, too.

In this video, we show you how to do this with an Auror – which is the best combination for faster challenges.

You can try doing this with random Professor and Auror match-ups and we’ve had some success with this.

Hope this helps some of you to keep fortressing for longer, even when you’re out of spell energy. If this helped you in any way, please consider giving the channel a like and subscribe so you’re notified about any future guide videos we make.
