This creature is a hideous blend of vermin and drake, with the body, tail and legs of a giant scorpion and the head, teeth and lethal breath of a dragon.

Special Abilities
Draconic Parentage (Ex) All scorpidrakes have some draconic blood in them. This blood alters the coloration of the scorpidrake, as well as its energy resistance and breath weapon to match the that of its parent type. These statistics represent a black scorpidrake.
Poison (Ex) Sting—injury; save Fort DC 23; frequency 1/round for 6 rounds; effect 1d2 Strength damage; cure 2 saves. The save DC is Constitutuion-based and includes a +2 racial bonus.

Whether the scorpidrake is the product of wizardly experimentation, draconic fecundity or deific malice, it is clearly not of natural origin. Its body is that of an immense scorpion, while its head is that of a chromatic dragon. The hue of the body is that of the dragon’s type – those with the head of a blue dragon have a deep azure shell, for example, while those with a black dragons head have a shell of obsidian tone. Only the neck and head are draconic; the creature has no forelimbs or wings.

Many scorpidrakes traits are draconic. They will make a lair, usually a small cave or hollow and they will gather what treasure they can into it. They are far too stupid to have elaborate traps or hired guards for their lair and so they hate to leave it, venturing out only for food and never straying too far. Scorpidrakes can speak a limited form of draconic but they rarely have much to say. Powerful beings can sometimes manage to get scorpidrakes to serve them, as long as food and treasure are provided regularly.

On Porphyra
Like dragons, scorpidrakes tend to be rare, but recently rumors have begun to spread about large clutches of scorpidrakes emerging from the Glass Sea to invade nearby Argentum, in the Creeper’s Rift and Ashyim, in the Wastes of Simoon.
