When disturbed, giant fire beetles bite with their mandibles.

These luminous nocturnal insects are prized by miners and adventurers. They have two glands, one above each eye, that produce a red glow. The glands' luminosity persists for 1d6 days after removal from the beetle, illuminating a toughly circular area with a 10-foot radius.

Giant fire beetles are about 2 feet long.
