Blastats are nocturnal omnivores that stand 2'-3' tall with wingspans reaching 6'-8' wide.  Their bodies pulsate with a scintillating, multi-hued light that can be quite entrancing...right up until the point it's focused through the crystalline structures on their snouts into a destructive energy beam.  Groups of 5 or more blastats can also Confuse targets by swarming.

Blastats make their home in caves and Ancient ruins, particularly abandoned power plants.  They are drawn to areas of high radioactivity, and for the traveler, circling swarms of blastats often serve as advance warning for upcoming hazardous environmental conditions.
