Powerful Charge (Ex): An urskan often begins a battle by charging at an opponent, hurling its powerful body at a foe. In addition to the benefits and hazards of a charge, this allows the urskan to make a single slam attack at a +11 attack bonus that deals 2d8+10 points of damage.

Rend (Ex): If an urskan hits with both claw attacks, it latches onto the opponent's body and tears the flesh. This attack automatically deals an additional 2d8+10 points of damage.

Scent (Ex): An urskan can detect opponents within 30 feet. The exact location is not revealed unless the creature is within 5 feet.

Surefooted (Ex): Urskans ignore all movement penalties associated with snow on the ground. They also receive a +4 racial bonus on Balance checks when walking on ice or snow.

Skills: *An urskan's white fur gives it a +8 racial bonus on Hide attempts while unarmored in snow or icy terrain (thus an unarmored urskan has a Hide check modifier of +5 in suitable terrain). An urskan gains a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.

Urskans are carnivores that depend on a diet of seal, walrus, and fish to keep them going through the long winters. As a result, they are astounding predators, and are especially dangerous in pack ice, where their swimming and ice abilities come into play. When on land, they often don heavy iron plate armor for battles to defend their territory, and add steel tips to their already deadly claws.

Urskans are proficient with simple weapons, their deadly steelclaws, and all forms of armor, but not shields.

Cold Subtype

A creature with the cold subtype has immunity to cold. It has vulnerability to fire, which means it takes half again as much (+50%) damage as normal from fire, regardless of whether a saving throw is allowed, or if the save is a success or failure.
