Glowbras are thick, muscular serpents that reach lengths of 12'-15' long, and they continually emanate a cobalt-blue light.  Resilient creatures, they thrive in the most polluted and toxic environs.

The bite of a glowbra is one of the deadliest in all the Mutant Future, as it injects a lethal radioactive venom.  A victim must make a successful Saving Throw Versus Poison, or die 1d4 turns later (from the Class 20 poison, with delay).  Even if the Save is made, the victim still suffers a permanent loss of 1d6 CON.

Glowbra eggs are highly prized amongst those sects of Mutant Humans that worship radiation, as ingesting the raw yolk bestows 1d3 random Mutations.

Mutations:  Accumulated Resistance (Pollutants), Optic Emissions (Radiation), Reflective Epidermis (Radiation), Toxic Weapon (Venom)
