This collection of nefarious villains and powerful patrons adds spark to your Dungeons & Dragons game. It's packed with powerful spellcasters, devious mobsters and deadly monsters galore, including: Statistics for powerful and unusual nonplayer characters you can drop into your own campaign. Ready-to-run minions, guards and thugs useful in dungeons, cities or wherever your adventures take you. Full descriptions of the D&D characters from the Player's Handbook - the characters that designers use to test new monsters and adventures for the D&D game.
This was intended to be a trove of useful NPCs, but... I dunno. I feel like it would have been better served with more helpful notes on how to make great supporting NPC casts, rather than just basically a list of characters you could drop into your campaign. It was okay, but it wasn't a book I re-opened often.
