Bearers of Precious Gems. The glimmering garnet in this creature's forehead-the carbuncle for which it is named-is more than just a precious stone. Alchemists and other arcanists spend exorbitant amounts on carbuncle hunters because the gem is rumored to hold the power to amplify magic like light through a magnifying lens. What few wizards understand is that the carbuncle's garnet only holds magical power if given willingly; a garnet pried from the skull of a slain carbuncle still shines beautifully (and is worth 300 gp in most markets) but is devoid of magic. If a carbuncle willingly removes the gem from its forehead and gives it to another creature, the gem regrows in 1d4 weeks.
