Bestial Awakening (Su) Curse—Nightmare targeting a creature that has seen the skinwalker’s eyes; save Will DC 26; onset 1 minute; frequency 1/day; effect 1d4 Wis drain (minimum Wis 1); cure 3 consecutive saves. When a victim’s Wisdom reaches 1, his alignment becomes chaotic evil and, if he is a Small, Medium, or Large humanoid without the lycanthrope template, he gains the lycanthrope template (with wolf as the base animal). Miracle or wish can remove a template gained in this manner and restore the victim’s alignment. The save is Charisma-based.

Haunting Gaze (Su) When a skinwalker uses its nightmare spell-like ability, the victim is also exposed to bestial awakening (see above) if the victim has ever seen the skinwalker’s eyes.
