A quick glint of refracted light, gone in the blink of an eye, might be the only warning before a skin-searing blast of lightning obliterates the unfortunate target of Glimmerdoom’s wrath. This mutated behir stalks ancient ruins, subterranean tunnels, and canopied rocky mesas. The creature’s mirrorlike hide bends light around its massive powerhouse frame, allowing it to mask its presence or distort and refract its image at will. Glimmerdoom is nowhere and everywhere, a deadly mirage bristling with electricity and hungry for scorched flesh. Worse yet for those who would challenge it, the mirror-plated behir reflects magic as easily as it does light, and spells hurled at it turn back on the caster more often than not.
