They were also known to freely exude an aura of fear that caused most to run in terror, and slowly regenerated when not harmed by good-aligned spells or weapons. The body of a gelugon, but particularly the tail, was surrounded by an aura of numbing cold that slowed those they struck.
Gelugons were savage warriors that fought their enemies with their claws, pincers and tails. While ice devils still schemed to obtain souls for their masters, they avoided complex plans and attempted to delay the end of their plans until after they were promoted. Their desire for the power held by the pit fiends ingrained not only diligent loyalty, but also a crippling fear of making mistakes. They begrudgingly cooperated with weaker devils, seeing them as either pawns or outlets for their frustration. Gelugons resented the weak and respected the powerful, regardless of their allegiances.
Their heads hosted a set of antenna, sharp mandibles, and a pair of multifaceted eyes. Their hands and feet ended in claws and their long, thick tails were surrounded in spikes. Gelugons were blue and white, insectile bipeds that stood about 10.5‒12 ft (3.2‒3.7 m) tall and weighed around 700 lbs (320 kg).
