Monstrous humanoids that resemble humans with snakes instead of hair, medusas are best known for their petrifying gazes that-if lingered upon-can permanently transform mortals to stone. Medusas are shrewd and manipulative adversaries who collect and covet secrets, and who use threats and guile to exploit the fears of weaker creatures. A medusa may seek out powerful magic items, use divination magic to discover secret knowledge and unlock forbidden power, or infiltrate a society to beguile influential politicians. Their ability to worm their way into powerful organizations makes them natural leaders of criminal outfits and thieves' guilds, and their interest in magical phenomena leads some to pursue careers as oracles who offer to help adventurers find what they seek-for a price. Of course, if wit and deception proves insufficient, a medusa can always simply turn rivals into ornate stone decorations with little more than a glare.
