Ancestral Weapon (Su)

By inscribing ancient dwarven runes upon his weapon, a skyseeker forges it into a reflection of the legendary weapons his ancestors bore during the Quest for Sky. When wielded by the skyseeker against a creature with the giant, goblin, or orc subtype, the weapon deals an additional 1d6 points of damage on a successful hit. As a free action, the skyseeker may also identify the weapon by name when making an Intimidate check against such creatures, granting him a competence bonus on his Intimidate check equal to 1/2 his class level (minimum +1).

At 4th level and every three levels thereafter, the extra damage dealt by the ancestral weapon increases by 1d6, to a maximum of 4d6 at 10th level. Forging a link between a weapon and the legendary weapons of old requires a 24-hour-long ritual, and only one weapon can be designated as an ancestral weapon at a time.
