Special Abilities

Carrier (Ex): The dermal plates were designed to be opened, allowing medium-sized creatures to ride. When a medium creature is riding in the plates, it gains the Brontosaurus’s EAC and KAC. The creature can carry up to 10 medium sized or smaller ‘passengers’.

Deadly Aim (Ex): The creature can take a -2 penalty to any attack it makes, and will gain a bonus of +7 to damage inflicted.

Dragon Gland, standard disruption (Ex): As a full round action, the creature can breathe a cone of disruptive energy. Anything caught in the area of effect is allowed a Reflex save (DC 19). If the save fails, the target will suffer 9d6 acid / sonic damage and if the target fails by more than 5, the target is also deafened until cured.

Earthquake stomp (Ex): As a full round action, the creature can rear up on its hind legs and come crashing down. This has an area of effect of 60 feet and anything in the area must make a Reflex save (DC 19)  or suffer 3d8+27 B damage and automatically be knocked prone.

Tail Sweep (Ex): As a full-round action, the creature can ‘sweep’ an area with its massive tail. This is treated like a 30 ft. cone for area of effect. Anyone caught in the cone must make a Reflex save (DC 19) or take 3d10+25 B damage and automatically be knocked prone. Those who make the save do not take any damage.

Trample (Ex): As a full-round action, the creature can move up to twice its speed and literally run over any opponents at least one size category smaller than itself. The creature merely has to move over the opponents in its path. The creature does not need to make an attack roll; each creature whose space it moves through takes damage. A target of a trample can make a REF save (DC 19) for half damage. If it attempts the save, it can’t make an attack of opportunity against the trampling creature due to the creature’s movement. The creature can deal trample damage to a given target only once per round.

Designed to be a major combatant, this particular dinosaur has the usual upgrades, such as heightened intelligence so that it can take and understand simple orders, heavy dermal plating, and built-in weapons. An Absolute zero hail cannon has been implanted on the top of its head, and it has a pair of forward facing inferno agitators, mounted on just above the front legs. These two cannons can only fire forward. With the additional upgrades, the creature is able to act as living APC, carrying up to 10 medium sized creatures into battle with it. Like the augmented Brachiosaurus, it can use its incredibly long neck to get behind enemy defenses and attack directly. The skeletal and musculature of the creature has also been strengthened, to allow it to move on land without difficulty. This is especially effective when the creature decides to use its dragon gland in this type of situation.
