MONSTERS (Di-Do)

DIGESTER

A digester stands about 5 feet tall and is 7 feet long from snout to tail. It weighs about 350 pounds,
COMBAT
A digester is a hunting and eating machine. When it is not hungry (which is rarely), it lies low and avoids most other creatures. When hunting, it looks about for a likely target, then charges forth and delivers a gout of acid. If the initial attack is insufficient to kill the prey, the digester attacks with its hind feet until it can spray acid again.
Acid Spray (Ex): A digester can spray acid in a 20-foot cone, dealing 4d8 points of damage to everything in the area. Once a digester uses this ability, it can’t use it again until 1d4 rounds later.
The creature can also produce a concentrated stream of acid that deals 8d8 points of damage to a single target within 5 feet. In either case, a DC 17 Reflex save halves the damage. The save DC is Constitution-based.
Skills: A digester’s coloration gives it a +4 racial bonus on Hide checks. It also has a +4 racial bonus on Jump checks.

DINOSAUR
Dinosaurs come in many sizes and shapes. Bigger varieties have drab coloration, while smaller dinosaurs have more colorful markings. Most dinosaurs have a pebbly skin texture.
COMBAT
Dinosaurs take full advantage of their size and speed. The swift carnivores stalk prey, staying hidden in cover until they can get into charge range and rush to the attack. Herbivores frequently overrun and trample their opponents.
DEINONYCHUS

A deinonychus is bright green along its back and flanks, with a much lighter shade of the same color on its underside. The body has darker spots or stripes. Its tail extends straight out behind itself, held aloft by an intricate structure of bony supports, thus allowing its weight to be carried entirely by the back legs. It weighs about 600 pounds.
Combat
A deinonychus uses a combination of speed, grasping forearms, large teeth, and hind legs with ripping talons. It hunts by running at prey, leaping, and ripping with its rear talons as it claws and bites. The talons count as one attack. A deinonychus has a relatively large brain for a dinosaur, and its pack hunts with cunning tactics.
Pounce (Ex): If a deinonychus charges, it can make a full attack.
Skills: A deinonychus has a +8 racial bonus on Hide, Jump, Listen, Spot, and Survival checks.

ELASMOSAURUS

Though it resides primarily in the water, an elasmosaurus only breathes air. An elasmosaurus has a total length of some 30 feet, including a tail half as long as its entire body, and weighs about 5,000 pounds. Observers who see only its head or tail might easily mistake it for a massive snake.
Combat
An elasmosaurus is aggressive and attacks anything it notices. The creature is strong, fast, and highly maneuverable, able to turn quickly and lunge at prey. When hunting, it travels with its head out of the water, snapping down quickly to seize prey.
Skills: *An elasmosaurus has a +8 racial bonus on Hide checks in water.

Combat
A tyrannosaurus pursues and eats just about anything it sees. Its tactics are simple—charge in and bite.

It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can try to swallow the foe the following round.
Swallow Whole (Ex): A tyrannosaurus can try to swallow a grabbed opponent of up to two sizes smaller by making a successful grapple check. The swallowed creature takes 2d8+8 points of bludgeoning damage and 8 points of acid damage per round from the tyrannosaurus’s gizzard. A swallowed creature can cut its way out by using a light slashing or piercing weapon to deal 25 points of damage to the gizzard (AC 12).
