Greater Krayt Dragon
The greater krayt dragon is a truly massive beast. This 100-meter-long desert titan lives among the endless dunes of Tatooine. A greater krayt dragon actually submerges itself in the shifting sands, and can use its ten powerful limbs to swim through the dunes.
Tatooine natives rarely see a living krayt dragon, although the titanic bones of these creatures dot the landscape and are highly prized as building material or trade goods. The gigantic reptile prefers to lurk under the warm desert during the day, moving about at night as it slinks close to the surface of the sand. A greater krayt dragon attacks with its massive jaws or whiplike tail; its claws have evolved exclusively for locomotion. Krayt dragons subsist on the largest prey, including herds of banthas and dewbacks. Anything that moves across a krayt dragon’s field of vision is fair game, though.
Greater Krayt Dragon Encounters
If a truly determined hunter were to penetrate the beast's armored hide and slay a krayt dragon, that hunter would be rewarded with an Emperor’s ransom in dragon pearls—ordinary stones polished to priceless perfection in the dragon’s stomach. A single such stone could fetch well over 100,000 credits. A greater krayt dragon contains 2d4+2 such polished gems.
Krayt dragons are always encountered singly—although it’s possible to run into a krayt dragon that is in the middle of assaulting a herd of animals, adding to the danger as these panicked animals run for their lives. Too stupid to notice (and too tough to care) that they aren’t edible, krayt dragon commonly attack land speeders, Jawa sandcrawlers, and other large vehicles. A krayt dragon’s lair can sometimes be discerned by the “melted” remains of some vehicle that sat a long time in the creature’s stomach before it was spat up as being indigestible.
Enterprising and extremely foolhardy hunters sometimes stalk krayt dragons with massive firepower or on swoops, allowing them to make numerous hit-and-run attacks, in the hope of killing a krayt dragon and stealing the dragon pearls inside. Predictably, casualties on such ventures are high.

Tremorsense—A krayt dragon automatically senses the location of anything that is in contact with the ground and within 100 squares (no Perception check required).
Camouflage—A krayt dragon’s natural coloration changes to mimic its surroundings. Krayt dragons ignore their size modifier when they make Stealth checks.
Devour—If a krayt dragon hits with its bite attack against a Huge or smaller opponent, it can automatically make a grapple check with its bite attack at its full bonus (even if it has already taken a full-round action). If the grapple check is successful, the dragon can begin devouring its target. Any creature being devoured takes 1d8+22 points of damage each round it is in the krayt dragon’s maw. When the creature reaches 0 hit points, it is swallowed by the krayt dragon and continues to take ld6 points of acid damage each round.
* Includes 10 points of Power Attack.
