Paizo loves to give you tons of free content for your games. And if you're looking to add a little, wild, goblin bomber to your Pathfinder adventure, they've got just that for you. You can head over and check out Gristleburst, the goblin alchemist now.
From the post:
The goblin alchemist Gristleburst is the fourth and final member of the protagonist adventuring party in the Pathfinder novella, The Shroud of Four Silences, by Pathfinder Tales veteran Liane Merciel. You can find the No-Prep Character (NPC) entries for his compatriots, Eleukas, Lisavet, and Wendlyn, on previous blogs. Check out the party’s full adventure here on paizo.com or on the Kindle bookstore.
