Gila Monster (heloderma suspectum)

One of the few poisonous lizards, the gila monster is a slow, sluggish creature with a terrible, painful bite. Though small in stature, the gila monster is incredibly strong for its size.

This lizard has a massive head, tiny legs, and a short, stout tail. It has brightly colored, bead-like scales that form gaudy patterns across its body. The gila’s scales do not overlap like those of a snake, and are rough in texture.

Combat: The jaws of the gila monster are extremely strong, and it can hold its tight grip for up to 15 minutes. An Open Doors roll is needed to remove the creature — or its death. The gila monster has 35 poisonous teeth that it uses to introduce lethal doses of venom. The teeth are not hollow, but grooved. Venom flows from sacks in the mouth, down the grooves, and into the victim.

The longer the gila monster is attached, the more chance there is for a victim to become poisoned. Following an initial saving throw vs. poison a penalty of -1 is applied for every round the gila monster remains attached, saving each round as more venom is introduced. The poison of the gila monster is hemotoxic, elevating the victim’s blood pressure.

Failing a saving throw means the venom has entered the bloodstream, causing extreme pain followed by sweating, vomiting swelling, and an unbearable ringing in the ears. Symptoms become gradually worse until death in 1-2 turns.

Habitat: The gila monster is found in temperate zones ranging from savannahs to light jungle regions. This creature is shy by nature, and does not attack humanoid creatures unless provoked. They seek shelter under rocks or in small burrows, which it often takes over from other animals.

Ecology: Gila monsters are nocturnal and very sluggish during the day. They feed on birds, eggs, and small mammals. The gila monster can go for months without food, living on fat stored in its tail.

Originally from Dragon #237 (1997).

Note that it should have "Heloderma suspectum" for the taxonomic name, not "heloderma suspectum".

Okay, to get things moving around here I've done a Homebrew which I'll post as a "Working Draft".

Feedback and Criticisms are as welcome as they've always been.

A thick-bodied little lizard with a short, fat tail and flat head. Its covered in rounded scales that resemble beads, colored in alternating dark and light bands.

The statistics presented here describe small, venomous lizards of perhaps a foot or two in length, such as a gila monster or beaded lizard. These slow-moving reptiles use their keen sense of smell to track down food and specialize in eating eggs.

These lizards do not have venom-injecting fangs like a viper snake, but have grooved "venom teeth" at the back of their mouth. They can only envenom opponents if they chew upon them to work poison into the bite wound.

A banded lizard is colored black or dull brown with bands of a lighter color – usually white, yellow or orange. They sometimes have reddish or pinkish scales on their heads.

A typical banded lizard is roughly a foot long and weighs about a pound. The largest species can reach two or three feet in length and can weigh up to 10 pounds.

Combat
These sluggish creatures only attack in self defense, but once they bite they hang on tenaciously and use venomous chewing to attempt to poison their opponent.

Improved Grab (Ex): To use this ability, a banded lizard must hit a creature of any size with its bite attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity. If it wins the grapple check, it establishes a hold and can use its venomous chewing attack each round thereafter.

A banded lizard's jaws have an astonishingly strong grip, giving it a +6 racial bonus to grapple checks to keep hold of or damage an opponent.

Poison (Ex): Injury (venomous chewing), Fortitude DC 11; initial damage 1d3 Str plus agonizing pain (–4 penalty on attack rolls, skill checks, and ability checks) for 2d6 minutes; secondary damage 1d3 Str plus agonizing pain for 1d4+1 hours. The save DC is Constitution-based.

Venomous Chewing (Ex): On a successful grapple check (including a +6 racial bonus), a banded lizard automatically deals 1d4–1 points of damage and affects its opponent with its poison. For each successive round of venomous chewing, the banded lizard adds a +1 circumstance bonus to the DC of its poison (max +4 DC).

Skills: Banded lizards have a +8 racial bonus on Climb checks and can always choose to take 10 on Climb checks, even if rushed or threatened.

* Banded lizards have a +4 racial bonus on Survival checks when tracking by scent.

Note: Originally appeared as "Lizard, Poisonous - Gila Monster". Name changed to match the "Giant Banded Lizard" in Sandstorm.

Originally appeared in Dragon #237 (1997).

Design Notes
Much of the stats come from the Horned Lizard in Sandstorm. The agonizing venom is based on the poison we came up with for our conversion of the Farrowdale Mouse, with the addition of Strength damage to match the Strength damage caused by the Giant Banded Lizard in Sandstorm.

That works for me overall, but I note that the original critter had 2+3 HD. What about bumping to 2HD?

Yes, I know. I deliberately cut the basic HD because a typical real-world Gila Monster is only about a foot long (roughly the same size as the Tiny 1 HD Horned Lizard in Sandstorm), which made 2 HD seem excessive.

Also, notice that the original critter is also Small size and 2 to 3 feet long, which is a better match to the Gila monster's bigger cousin the Beaded Lizard.

It seemed a more accurate match to their real-world counterparts to have the Banded Lizard start out Tiny and advance to Small size, to covered both "ordinary" and "jumbo" size specimens.

I've been wondering about giving them Advancement of 2-3 HD instead of just 2 HD. What do you think of the notion?

Yeah, that seems sensible. Let's have advancement go up to 3HD.

I'll go along with Toughness(B), as well.

Did you finish these up already?
