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.

Somewhere in the world lies the lost valley of Tlactoztlan. The strange natives of this hidden place practice human sacrifice, pray to bizarre gods, adorn themselves with brightly-colored feathers, and – it is rumored – live in cities made of gold. Only the bravest and luckiest adventurers find their way to Tlactoztlan!

Deep within the jungles of Tlactoztlan there are giant red and black centipedes, some measuring well over 4 feet long. These horrifying predators possess a deadly, necrotizing poison which continues to harm those it has afflicted for days after they have been bitten.

Xotlatocazatl, as they are called in Tlacuatl, live primarily on the floor of the jungle, nesting under stones and dead wood, as well as inside logs. They do occasionally climb high into the canopy in search of prey, and sometimes drop form branches to ambush unwary travelers.

Anyone bitten by a Xotlatocazatl must make a Tough Strength-based task check when the adrenaline of combat has cleared his or her system. Failure indicates that d3 of damage is dealt from the poison. Success results in only a single point of damage. Twenty-four hours later a new Strength-based task check, which will either be Tough (if the initial check failed) or Hard (if the initial check succeeded). Failure of this check again results in d3 damage, while success yields a single point of damage. This cycle continues every twenty-four hours, with the task check becoming progressively easier after a successful check (up to Moderate difficulty) or remaining at the difficulty level of the last successful check. Once a character has succeeded in four successive task checks the poison ceases to be damaging.

Damage done by Xotlatocazatl poison cannot be healed by any normal means until the poison has been purged from the victim’s system.
