Monster Manual III
Blood Squirt (Ex): Every 1d4 rounds, a bloodstriker can project a 30-foot line of its acidic blood as a standard action. Anyone in the area takes 2d6 points of acid damage (Reflex DC 19 half). The save DC is Constitution based.
Caustic Blood (Ex): Any creature successfully striking a bloodstriker with a melee weapon or natural weapon takes 1d6 points of acid damage from the dinosaur's highly acidic blood. Weapons with exceptional reach, such as longspears, do not endanger their users in this way.
Spiked Skin (Ex): A bloodstriker's thick skin bristles with defensive spikes. Any creature attacking a bloodstriker with a melee weapon or natural weapon takes 1d8+6 points of piercing and slashing damage from the dinosaur's barbs. Weapons with exceptional reach, such as longspears, do not endanger their users in this way.
Skills: *Bloodstrikers gain a +4 racial bonus on Hide checks when they burrow underground to hide. They lurk just below the surface of the ground with only their eyes and the tops of their heads exposed.
A bloodstriker epitomizes tough natural defenses. Thick, spiked plates cover its body, providing both excellent natural armor and protective spikes apt to damage any creature adventurous enough to attack it. Those that successfully attack are sprayed by the dinosaur's caustic blood, providing further dissuasion. In addition, the creature has an unusual attack whereby it squirts its acidic blood from its eyes. It usually uses the blood squirt as a defensive measure when confronted by persistent foes.
