Let me tell you, when E.R.F got a hold of me to take a look at this bad bumpkin, I was more than happy to - and I gotta say this is one of the most interesting books I have every looked at. In 56 pages, E.R.F manages to slam you with a ton of new content in revamping, bringing back, and utilizing the vestiges from 3 and 3.5 in the world of 5e. So for those of you that don't know, vestiges are strange chaotic entities who exist in the nether between all the physical planes, and they are TERRIFYINGLY AWESOME! You have a huge slew of sweet new vestiges to work with, as well as rules on how to work with binding and pact magic with vestiges, as well as cool new magic items and handouts with printable cards of each vestige. One of the best things I think E.R.F did with the vestiges here is that they have an physical toll on the binder, for instance - with Amon you grow black rams horns, with Eligor one of your hands is covered in scales - and so on. It has so so much roleplay potential as well as new gameplay mechanics, and it is the sheer amount of work that E.R.F put into this project that makes me honored to give it the Comics, Clerics, & Controllers Golden d20 Badge.
