Upper body of a beautiful woman, lower body of a venomous snake
With the upper body of a beautiful woman, and the lower body of a venomous snake, Lamia are dangerous monsters often found near human settlements, where they prey on unsuspecting stragglers from the settlement, especially favouring children.
A lamia possesses a poisonous bite that causes paralysis for 1d4 turns when a victim fails a save vs. Poison. It uses this poison to subdue its prey before devouring them. A lamia can wield weapons, often favoring bows, spears, and pole-arms.
A lamia can also constrict its victims in the coils of it's lower body, they must first successfully grapple its target. This requires a successful attack roll. If the attack roll is successful, the lamia can then wrap its lower-body around the target, beginning the constriction. Every round after that, the lamia automatically deals 2d6 points of constriction damage. Their hold may be broken by rolling beneath the characters strenth on 1d20.

Upper body of a beautiful woman, lower body of a venomous snake
Lamiai like to live in deserted towns, ruins, and other desolate places. These creatures have the upper body of a woman and the lower half of an animal.
Typically a lamia is armed with a dagger, but these are really just tools. Lamiai are able to cast these spells once per day: charm person, mirror image, suggestion, and illusion (like the wand). They use these spells to lure their victims and then hold them. The touch of a lamia permanently drains a single point of wisdom; once their victim's wisdom falls below 3 they will do as the lamia instructs. The lamiai like to drain their victims' blood, then devour their flesh. They speak the common language.
