Since the release of 5.5e I feel that theres been a real drought of official content. So as a dm who loves to read sourcebooks to draw inspiration from I want to try out using more 3rd party content, I am especially interested in content that adds more gameplay options for the dm like interesting statblocks, magic items and dungeons. I prefer physical book content but Im willing to try online only if its good enough. Theres famous stuff like Grimhollow which sponsors so many youtubers but what experience do people actually have with such content?
