Praester

Praesters are a magical breed of asp that originated in Medieval Europe, but has now spread around the world.

Appearance
Praesters are magical beasts that look similar to mundane snakes, however, they are mostly a light bluish-gray color, the color of steam.

Behavior
Despite their appearance, praesters, for all intents and purposes, behave much like their mundane cousins.

Powers

 * Snake physiology:  Praesters possess the main powers and abiities of snakes (basically look at the amphisbaena page, but without the extra head powers).
 * Steam breath:  Praesters possess the ability to exhale clouds of scalding hot steam.
 * Steamy venom: Praesters possess venom that not only burns when injected, but turns to steam/hot air when it enters, which, if left untreated, will basically inflate the victim like a balloon, lift them into the air, and eventually make them explode.
