With a tip of the hat to Jeff Mejia of Evil DM Productions for his outstanding work in the BoL version of Legends of Steel, I present the Giant Snake (Tlactoztol variants).

From the tall grasses of the plains, to the dark depth of the jungles, to the fetid swamps, and sometimes even in the sewers and catacombs beneath the cities – cold-blooded death awaits the unwary in the lost valley. Whether striking with poisonous fangs, constricting with powerful muscles, or killing freely with both approaches, Hueyacoatl – the giant snakes of Tlactoztlan – pose a serious threat to human and animal alike.

Hueyiztlacoatl (Giant Venomous Snake)

Hueyiztlacoatl venom is a neurotoxin that impedes muscle movement, including the functioning of heart and lungs. Victims of a Hueyiztlacoatl bite must make a Hard Strength-based task check or be paralyzed for one hour. At the end of the hour – if the victim has somehow not been consumed by the snake – a second task check, of Tricky difficulty, must be made. On a success the victim shakes off the effects of the poison and recovers. On a failure, however, the victim expires.

Hueyaquilpicoatl (Giant Constrictor Snake)

A victim of a Hueyaquilpicoatl’s constriction attack may attempt to break free each round after the initial successful strike by making a Strength-based task check with the snake’s own Strength as a negative modifier. You might want to spend a Hero Point on that, son.
