As a standard action, an amarok can bite directly into the soul of any creature it can see. A shadowy image of the bitten creature appears next to the amarok, and the amarok makes its bite attack as if the creature were within reach. A soul bite deals the same amount of damage as a normal bite attack, and ignores hardness and damage reduction. If its bite attack hits, the amarok can attempt to trip and grab the target. When the amarok grabs a creature in this way, the creature doesn't move, but the amarok visibly wrestles with the shadowy image and the creature appears to be grappling with thin air. This ability doesn't work against creatures that don't have souls (like most constructs) or that don't have a separate body and soul (like outsiders).
