A Troll Charm is a magical item found in Underside and are given to beings that show traits that are favorable to Trolls (such as being rude, selfish, cruel or chaotic) - as long as a Troll Charm is in one's possession they are granted the ability to manifest a single power of their choice, providing it is not a power that can be utilized to gain "godlike" power (for example one could not be granted reality-bending or omnipotence).
