Kobold Press - Deep Magic Volume 1 the same a Deep Magic?

Hello, I searched the forums and didn't see and answer, can anyone tell me the difference between Kobold Press's "Deep Magic" and "Deep Magic Vol. I"?&nbsp; I already have Deep Magic (and I really like it), but I don't want to re-buy the same compendium content.

You might find better results searching online rather than Roll20. That way you are looking for more than just the digital conversion of the existing book. For example I found this reddit post on the topic.

Thanks!
