A Lightning Dracomander resembles a giant snake more than 12 feet long with two dragon-like heads (with long serpentine necks) and a pair of dragon wings. Its scales are all the colors of lightning: white, blue, purple, and yellow. A lightning dracomander constantly emits little bolts of lightning; all non-lightning-resistant creatures within 20 feet of the monster suffer 1d8 points of damage per round from being struck by them. Lightning dracomanders are immune to damage from any type of electrical or lightning attack.

A lightning dracomander may project its breath weapon from either mouth, or even from both, but cannot use the breath weapon more times than it has hit dice in any day (an adult lightning dracomander cannot use its breath weapon 9 times per day from each mouth, but rather 9 times per day total). Anyone in the area of effect of both breath weapons in the same round suffers damage only from one of them (generally the one with the higher damage total).

As with the lightning salamander, this monster has only one mind despite having two heads.
