Publisher's blurb: Strixhaven Supplemental Volume I: Course Catalog and Staff Directory is a companion to Strixhaven: A Curriculum of Chaos. This first volume contains 127 new and unique classes, each with their own punny or humorous name, to offer your players during their time at school. Each class comes with example ideas for DMs to use in terms of homework assignments, lab sessions, and exams as well as associated skill checks and other rolls for DMs to use for roleplay purposes. Each class in this book comes with it's own reward. Using the school setting each player essentially can learn magic like a Wizard without needing to multiclass and gains spells for successfully passing classes. These spells are meant to be used instead of the spells granted in the new, published backgrounds. Additionally included are 31 new professors and staff of all manner of races and gender identities, each with their own personalities and backstories. There are also additional details on the published faculty so DMs have more than two to three sentences to use when building personalities for the published faculty.
