@JeremyECrawford is the Explorer's Guide to Wildemount considered official D&D material? Certainly Mr. Mercer is an expert weaver of tales and is very familiar with the mechanics but are these subclasses, items, and spells tested? Has it gone through what other books go through?

EXPLORER'S GUIDE TO WILDEMOUNT is a delightful introduction to the world of @CriticalRole. Like every D&D book, its rules have been tested by players, developed by the D&D team, and vetted by me. There are juicy subclasses, spells, magic items, and monsters awaiting you! #DnD https://t.co/by9s5P8tK9
