Blood Drain (Ex): If a tundra landwyrm gets a hold on a living foe, it can drain blood with a successful grapple check. Each successful grapple check deals 1d6 points of Constitution damage to its target. A single landwyrm can deal as many points of Constitution damage in a day as it has Hit Dice.

Frightful Presence (Ex): 120-ft. radius, HD 23 or fewer, Will DC 23 negates.

Improved Grab (Ex): To use this ability a tundra landwyrm must hit a creature of its size or smaller with a claw attack. If it gets a hold, it can attempt to draw blood. It can also attempt to start a grapple as a free action without provoking an attack of opportunity.

Snatch (Ex): Against Small or smaller creatures, bite for 2d8+8/round or claw for 2d6+4/round.

Cold Adaptation (Ex): Tundra landwyrms take no non-lethal damage from exposure to low temperatures (though this ability doesn't affect normal cold-based damage). They suffer no ill effects (such as penalties on Spot checks) from snow or sleet and can walk across icy surfaces without needing to make a Balance check.

Skills: *Tundra landwyrms have a +4 racial bonus on Hide checks when in cold desert or plains environments. This bonus on Hide checks increases to +8 when the landwyrm is immobile.
