In this 3rd installment of the S&W Appreciation Day series, I thought I might pass along some new monsters, scavenged up from my favorite medieval bestiary:

First up is the Amphisbaena
Hit Dice: 6
Armor Class: 5 
Attacks: Bite (2d6) + poison
Saving Throw: 11
Special: Poison (+2 save or die in 1d6 hours), Immune to Cold, Can not be attacked from behind
Challenge Level/XP: 8/800
A fearsome serpent, this beast has two heads. One in the usual location, one at the end of its tail. Amphisbaena are spawn when the blood of a gorgon spills upon a common serpent. They are, unlike many serpents, often found in cold environments where they lure lost and weary travelers with their glowing eyes which, from a distance, appear like lamps from a village. Their jaws drip with venom and their poison causes painful convulsions which can last for hours before the victim finally dies.
Next we have a Leucrota
Hit Dice: 4
Armor Class: 6 
Attacks: Bite (1d6) or Kick (2d4)
Saving Throw: 13
Special: Suggestion, Intelligent
Challenge Level/XP: 6/400
This swift beast has the head of a horse, the chest of a lion, the hind of a stag and cloven feet, the twisted result of a mating between a hyena and a lioness. But it’s most distinguishing feature is its mouth, which grins widely from each to ear, and is not filled with teeth, but rather a single bone where the teeth should be. Wiley and cunning, it is said that the Leucrota can imitate the speech of humans, and that it is dangerous to listen to its voice, lest it place you under a spell.
