Boom, baby! If you're looking to add some explosions to your games of Pathfinder, you should head over to this article where you can find Redpitch Bombs. These thrown incendiary devices will certainly add some brightness to your games.
From the article:
A distinctively sharp and somewhat minty smell alerts travelers to the presence of redpitch pines, trees that have grown around Otari since before the town was founded. Redpitch wood isn’t much prized, as it catches fire dangerously quickly and burns fast, but its flammable sap is useful in many alchemical concoctions. Eager alchemists here often make volatile concoctions with redpitch pine sap, including incendiary bombs.
