 What separates it from past volumes is the level of detail given to each creature subtype, including probable behavior in combat and even a complete pre-prepared encounter complete with a map.While the 'standard' entry still clocks in around two pages, many of the 'expanded' entries are four pages or longer, with the 'Spawn of Tiamat' section going on for nearly forty pages, or 20% of the entire volume.This results in fewer overall monster entries, which proved unpopular among many D&D players.
