Dragonblood Subtype: Frostblood orcs are of the dragonblood subtype (see page 4).
Endurance: Frostblood orcs have Endurance as a bonus feat. If a frostblood orc would later gain Endurance as a bonus feat, he can select any other feat for which he qualifies.
Light Sensitivity: Orcs are dazzled in bright sunlight or within the radius of a daylight spell.
Resistance to Cold 10: Because their ancestors ingested the blood of great white dragons, all frostblood orcs are naturally resistant to damage from cold-based attacks.
Vulnerability to Fire: Frostblood orcs share the white dragon’s vulnerability to fire-based attacks.
