Are your d20 monsters....correct? Meet ENWorld staff reviewer John Cooper, known as "the nit-picky stat block guy". He's been invited by Dog Soul to comb through the core monsters and correct anything that seems amiss. Fully bookmarked and easy to print, each pdf also includes "Cooper's Comments" sidebars, which explain what John changed and why he made the changes that he did. "Cooper's Comments" also prompt the DM to check for possible synergy bonuses in instances where a given creature has a skill or skills that still need to be plugged in, like “Craft (any)” or “Knowledge (any three).” Cooper's Corrected Creature Codex - the definitive monster resource for both GM's and d20 publishers.
