Pathfinder 1e Monster / NPC: Mistress Of Torment

The horrifyingly sadistic shamans of a mutant tribe, a Mistress Of Torment takes pleasure in capturing victims to use as their playthings. They rip open the poor person's back and use their sinew and tendons as strings for a harp. The frame of which is grafted onto their bodies while they are still conscious. This is then enchanted to created a fearful weapon, known as a Heartstring Harp. The screams of agony as the Mistress plays this harp is turned into a psychic attack used against any of those unfortunate to stray too close to a mutant tribe. For every one successful creation, there are many that died in the process.   A Mistress Of Torment will spend their lives perfecting their art of pain and misery in order to increase their own feelings of sadistic elation. These Heartstring Harps are by no means the extent of their debauchery, they also use other captives as mere objects to experiment on, leading to unspeakable torments. But these harps are their pride and joy.
