Combat

Remorhazes hide under the snow and ice until they hear movement above them, then attack from below and surprise prey.

Improved Grab (Ex): To use this ability, the remorhaz must hit with its bite attack. If it gets a hold, it automatically deals bite damage and can attempt to swallow the opponent.

Swallow Whole (Ex): A remorhaz can try to swallow a grabbed opponent of Large or smaller size by making a successful grapple check. Once inside, the opponent takes 2d8+12 points of crushing damage plus 10d10 points of fire damage per round from the creature's blazing gut. A swallowed creature can cut its way out by using claws or a Small or Tiny slashing weapon to deal 25 points of damage to the remorhaz's gut (AC 20). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out. The remorhaz's interior can hold two Large, four Small, eight Tiny, sixteen Diminutive, or thirty-two Fine or smaller opponents.

Heat (Ex): An enraged remorhaz generates heat so intense that anything touching its body takes 10d10 points of fire damage. This is usually enough to melt nonmagical weapons, but magic weapons get a Fortitude save (DC 18).

Tremorsense (Ex): A remorhaz can automatically sense the location of anything within 60 feet that is in contact with the ground.

Skills: Remorhazes receive a +4 racial bonus to Listen checks.
