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. Grassland wurms can exhale a line of magic causing foes to become confused. Creatures in the area must make a Will saving throw or behave randomly as if under the influence of a confusion spell for 1d4 rounds. This is a mind-influencing compulsion enchantment.

Trample (Ex): A grassland wurm can trample any creature smaller than itself for 2d6+2 points of damage (DC 14). Opponents who do not make attacks of opportunity can attempt a Reflex save to halve the damage.

Sprint (Ex): Once an hour, a grassland wurm can take a charge action to move ten times its normal speed (600 feet).

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.
