Covered in overlapping chitinous plates, dune crawlers resemble elongated wood lice — also known as pillbugs. The remaining essence left from a fallen titan mutated these creatures into the enormous, carrion-eating desert dwellers they have become. A full-grown Crawler can be up to 20 feet long and be six feet high at the top of its back. They are not temperamental creatures and tend to be easy to handle. Combined with their stamina, they are ideal pack animals for long desert voyages.

Because of their adaptation to desert living, they are commonly used as transportation through arid areas for caravans. A single Dune Crawler can carry two human-sized riders and 500 pounds of cargo without straining. More riders can be added (up to a total of four) by sacrificing the cargo capacity. A Crawler with no riders could carry up to 1,000 pounds of cargo, as long as someone walked or rode alongside to lead the beast.
Dune Crawlers have resistance to slashing damage because of the hard, chitinous plates covering nearly their entire upper body. Their body is segmented, and each segment has a pair of legs - one leg on each side - that propel the Crawler along at a steady rate of 20 feet per round. While not fast, these creatures are highly prized for their endurance, capable of traveling at the same rate for up to twelve hours a day with no ill effects. Their water consumption is minimal: they gain most of the liquid they need from their food. Because they have adapted to a diet of carrion, they are not interested in eating anything freshly killed. If there is a difficulty in using these animals for long-range transport, it is keeping them supplied with rotting meat for the entire journey, though their diet can be supplemented with rotting wood or vegetation for a few days with no ill effects. They typically eat 10 pounds of meat per day. Though they can go without eating for up to two days, they will need to eat enough in one sitting to “catch up” with the food they missed.

Crawlers tend to wiggle down into the sand, with only the tops of their backs exposed, to stay warm during the cold desert nights. When attacked, they thrash the front half of their bodies back and forth, doing 4d6 bludgeoning damage to anyone not able to dodge or move out of the way. Riders on a Crawler defending itself in this way must make a DEX save to hang on and can do nothing else until the beast is dead or no longer being attacked. Riders flung off will take 2d4 bludgeoning damage from hitting the ground.
