Task Master Demon

9 foot tall, but due to their posture, stand at 7 foot. Large Creature.

Large scaly humanoids covered in small spikes. From its back sprout these large spiked bony bat wings, but with no membrane between them.

They've got a pair of long curved bony plates that extend from the ridges of their eyes up and out. From their small palms extend three elongated and slightly webbed claws slightly sticking out. Their legs are kind of canine, with that weird back and forward thinker like a dog's back legs, but its feet are broad and short and covered in talons.

It carries a curved sword of obsidian and a whip. Seem to have +15 to hit using their sword and whip. While they are in the Prime Material Plane, they do not appear to have this high of a hit bonus.

It can let out a tremendous roar that deals minor damage(9, 3d6?), stuns for 2 rounds and deafens for 4 if you fail a saving throw vs breath weapon
