Sorrowsworn demon A sorrowsworn demon was a breed of tanar ' ri demon that preyed upon feelings of grief and loss . Description . A sorrowsworn demon was a gaunt humanoid standing some 12 – 15 feet ( 3 . 6 – 4 . 5 meters ) tall and weighing 500 pounds ( 230 kilograms ) . It had hooked claws for hands , a dusky black hide , and slender bat - like wings emerging from its back . Its face was a demonic , skeletal visage contorted into a mockery of utter grief , with a wide toothy maw and two short and twisted horns upon its high brow . Powers . At a whim , this demon exuded an aura that provoked creatures within 30 feet ( 9 . 1 meters ) to suffer intense feelings of despair and personal loss , constantly imagining the worst bereavements and failures they ' d ever known or could dread to know . Those of iron will could shrug off such thoughts ; the rest were overwhelmed and distracted and weakened by them . When in battle or tormenting a victim , a sorrowsworn demon hissed and whispered incessantly , both in voice and in the mind . It could affect one thinking being at a time , to a distance of 60 feet ( 18 . 3 meters ) , and could change the subject of these mutterings to provoke different responses . If it whispered of past losses , whether real or made - up , a victim would become dazed as they thought on these . If it spoke of the great emptiness of history , of genocide , massacre , tragedy , and pointless sacrifice , a victim might become dangerously confused . If it promised future sorrow or taunted its victim with the futility of fighting against the inevitable , they would become stunned with fear . Only a strong will could ignore these whispers of loss . It was also a mind - reader , using " detect thoughts " to raid the memories and thoughts of its intended victims for true losses and fears to taunt them with , making them more vulnerable to its whispers of loss if they were caught within its aura . As a demon , it could also communicate via telepathy to any within 100 feet ( 30 meters ) who spoke a common language , enabling to transmit its cruel whispers . As a master manipulator of the mind , the sorrowsworn demon was well inured to similar tactics , possessing an unholy will and a resistance to spells . In addition to such supernatural powers , the sorrowsworn could cast the innate spells of " detect magic " , " invisibility " , " nondetection " , " greater teleport " at will ; " greater dispel magic " , " touch of idiocy " , " unholy blight " thrice a day ; and " feeblemind " , " mind fog " , " plane shift " , and " weird " but once a day . However , it lacked the power other demons had to summon others of its own or lesser kind . The sorrowsworn demon was innately good at stealth and survival , and was well - practiced in deceit , intimidation , and knowledge of lore and magic . It had extremely keen senses and obscenely great strength and resilience . Tactics . A sorrowsworn demon preferred to prey on its victims from hiding , using its skills and spells to remain unseen and unknown as its spied on its targets , reading their minds and gauging their strength . It then appeared suddenly among them , using its powers to weaken them before finally slaying them . It favored a " + 2 glaive " , striking brutal blows to swiftly fell its opponents and follow through to another . It could also smash items . Activities . Sorrowsworn demons preyed upon folk who ' d suffered great loss or sorrow . They coaxed them to ever greater depths of grief , and consumed such feelings . Creeping out from the Abyss , they only appeared in the material plane after a battle or war had come to an end , to feast on the sorrow that saturated a land with the cutting short of its youth and potential . They often lurked about hospitals for the wounded , orphanages for those left without parents , the homes of bereft people , and at mass graves . Such places offered the greatest density of souls suffering loss to feed upon . Following the war against the Tuigan Horde in 1360 DR , sorrowsworn demons were to be found in the populations of those realms who ' d lost their kin to the invaders , such as Cormyr , Sembia , Rashemen , and Thay . They were also known to haunt fallen temples , eating the despair of cleric s forsaken by dead gods like Bhaal and Myrkul , after their deaths in the Time of Troubles of 1358 DR .
