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 storm wurm's breath weapon is a cone of stunning lighting (4d6 electricity damage). Creatures in the area must succeed at a Reflex save to take half damage. Any creature damaged by the lightning is also stunned for 1 round.
Scent (Ex): A storm wurm can detect opponents (even invisible or hidden foes) within 30 feet by sense of smell. Storm wurms can also use this ability to follow tracks by smell. For a full description of this ability, see the Monster Manual.
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.
