Spined devils were winged, porcupine-like Devils that delivered messages to more powerful members of their kind. Covered in spines and yet completely spineless, they were often bullied by other intelligent devils due to their weakness and were only able to torment the few beings weaker than them in turn.
They resembled 2‒3 ft (0.61‒0.91 m) tall, 25 lb (11 kg) Gargoyles. They had long, keen talons at the ends of their hands and feet, and spines bristled their whole bodies. Contributing to their traditionally devilish appearance were the military forks they often carried, and their muted, glowing red eyes. They emitted high-pitched giggles and shrieks so obnoxious that even other devils found them grating.
In order to engage in their love of torture and torment, spined devils traveled in flocks to compensate for their small size. Although their lack of intelligence made them loyal, it diminished their capacity to act as useful agents, as they were incapable of discerning important and irrelevant information. Due to not properly understanding the purpose of collecting treasure, they did not carry valuables unless instructed to.
Spined devils could fire the spines from their bodies and tails which would burst into flame once launched, burning those hit and igniting flammable materials. The amount of spines they could fire was agreed to be about two every few seconds. The spines were said to be poisonous and could be fired from the air, although if forced into melee they could claw at their opponents with their talons or hurl themselves at their enemies.
