Obviously this is material supporting a game using published materials. All concepts and other materials drawn from publications relating to Dungeons and Dragons, 5th edition are meant to be within fair use and the intent of those materials to support an active, creative game. Occasional other references to characters or ideas in other media, such as Rich Burlew’s Order of the Stick, are also meant to be within fair use, and are removable upon appropriately-documented request. Any materials that seem very derivative obviously are — that is much of the point of D&D, to ransack a larger popular culture for fun game material.
