Breath Weapon: Wurms create special liquids in sacs behind their jaws. Once a wurm uses its breath weapon, it can't use it again for 1d4 rounds. A blast from a breath weapon always leaves from the wurm's mouth and extends in the direction of the wurm's choice. A sand wurm can exhale a cloud of contact poison that extends outward from the wurm in a cone. Creatures in the area must make a Fortitude saving throw when first exposed to avoid the initial 2d6 poison damage and a second saving throw minute later. Dexterity damage is temporary. Unconsciousness lasts for 1d3 hours.
Tremorsense (Ex): While underground, a sand wurm can automatically sense the location of any moving thing within 90 feet that is in contact with the ground.
Sand Walk (Ex): A sand wurm is as sure-footed on shifting sand as on solid ground and never needs to make a Balance check to move on sand during normal conditions.
Improved Grab (Ex): To use this ability, the wurm must hit with its tail slap attack. If it gets a hold, it can constrict.
Constrict (Ex): The wurm can coil around its prey to deal its constriction damage plus tail slap damage with a successful grapple check against any creature of equal size or smaller.
Keen Senses (Ex): Wurms see four times as well as a human in low light conditions and twice as well in normal light. They also have darkvision with a range of 60 feet.
Spells: A wurm knows and casts divine spells as a druid as shown below, gaining bonus spells for a high Wisdom score.
Skills*: Wurms have a natural coloration and limited chameleon ability that grants them a +8 racial bonus to Hide checks in their home environment (a forest wurm in a forest). In addition, wurms with a climb or swim speed receive a +8 racial bonus to Climb or Swim skill checks depending on which movement type they have.
