Carnivorous Coin

From publisher blurb: Each release for Crawthorne's Catalog of Creatures for the Pathfinder RPG presents a single, new creature for your Pathfinder RPG game, as presented by the famous and retired monster hunter and adventurer, Lord Crawthorne. Each release presents game stats for the new creature, as well as three adventure ideas to help insert them into your game. The Abroa, also known as a carnivorous coin, is capable of camouflaging itself to appear to be a precious coin. When disturbed, however, it reveals its true nature and attacks with piercing mandibles and dripping acid. Game stats are provided for a single abroa and an entire swarm of the nasty coin creatures.
