The world of RPGs would be a dull place without monsters. Your heroes would probably spend time filling in tax returns, taking cookery classes, or maybe sharpening their two-handed deathblades ready to carve the dinner. Thankfully, with the Pathfinder Bestiary there are monsters. Lots and lots of monsters. All the boxes are ticked, whether you're looking for full-on vampire badness, underworld hideousness demons, fantasy fare giants, or heavenly angels. Every bit as important are the extensive collection of rules to advance your monsters, the thoughtfully presented lists designed to speed you towards the perfect monster fit for your next encounter, and a host of other small but perfectly formed touches that denote a product of genuine quality. And just in case you still want more monsters, there's a great section for building effective and balanced monsters of your own. The perfect monster mash-up!
I love this book. The art, the writing and the rules are all very solid and give you pretty much every classic Western monster you will want to bring into a game. All I feel it is missing is Easter mythology, which is expanded in Bestiary 2 and 3, so I'm more than happy with the first book as it is.
