Hello, how to get spells and potions?

After you've been on the site 10 days, and made 20 posts (not in the game room), you will unlock the homework, where you can complete it to earn spells!
(sorry if that wasn't very clear...)

Mirada Johnson is right. In addition, you can also buy them from shops on the Hogwarts's Fifth Floor (for spells) and Potions Classroom (for potions). Just make sure you read each item's requirements before you buy them so you can use them in RPs.

Thanks!
