Melpomene was once the Muse of Song, and the Mother of the Sirens. One day she fell in love with the great hero Farnir, becoming infatuated. The two were married, Farnir completely oblivious of his wifes divine origins, and they retired to a quiet life alone in a small village, Farnir happy to leave behind his days of grandeur and adventure for the woman of his dreams.
Farnir and Melpomene were not to live in peace for long, however, the retired adventurer had made a fair number of enemies, and before long they found him, the village burned, their children dead, Farnir and Melpomene wept tears of bitter rage and Farnir swore a solemn oath of vengeance. But the slope into darkness is steep and slippery, and as Farnir hunted down those who had wronged him, his soul slowly blackened, sacking whole towns, looting evil artifacts of power, all in the name of his children and his village. Melpomene's soul followed suit, her songs turning to funeral dirges and her heart turning harder and harder, neither realized when or how they had crossed the threshold to evil, gradual change is insidious that way.
Farnir hasn't been seen in an age now, and is assumed dead, his hidden tomb rumored to be full of his bloodstained riches. Melpomene languished in his absence, the only light in her immortal life, now snuffed out. Her twisted heart festered until she was reborn, as the demon now known as Mormo.
Hmm... So, I would give it like... 3 Songs of Discord (which any bard worth his salt can countersong and also learn afterwards) that it switches between during battle, while relying on it's minions and brute strength for actual damage First would be like Song of Kinslaying - 30' AOE centered on the demon that causes a DC 16 Will save or you have to move towards and attack your nearest ally, can be countered by calm emotions or countersong, the demon would lead with this, as it distracts and disorganizes his enemies, allowing him to close the gap and wade in while their in chaos Next would be Song of Corruption - Which heals all fiends within the 30' AOE and causes any good aligned creature to take Necrotic Damage, DC 16 Con save for half, I'd go with something like 2D8, save for half, and fiends heal for 2D8, because he can use this constantly it's pretty brutal and increasing those numbers can lead to TPK pretty easily Lastly would be the fiends trump card Song of Death, which causes any living creature that hears it to take 10D8 damage, DC 15 Charisma save negates and grants 24 hour immunity. This dmg bypasses ALL damage reduction so the barbarian is gonna be pretty tilted Being Deafened, casting silence, or otherwise preventing the music from reaching your ears is the only way to negate the effects of the Songs of Discord Give the demon a buttload of HP and resistances, maybe make it vulnerable to bardic magic in someway and give it like... 2 claws that deal 2d6+6 damage on hit
