Arctic Bound (Ex)

When Ithaqua is south of a planet’s arctic circle or on a planet without a magnetic north, he is staggered.

Arctic Dreams (Su)

Any creature that has ever looked into Ithaqua’s eyes or has committed cannibalism can be targeted by the Great Old One’s arctic dreams regardless of distance, even across planar boundaries. If such a victim fails its save against Ithaqua’s nightmare spell-like ability, the damage it takes from the ability is cold damage. Upon awakening, the victim is affected by a geas/quest to travel north beyond the arctic circle and, once there, await Ithaqua’s arrival in a remote location.

Whether or not the Great Old One comes to call is left to the GM to decide, but if Ithaqua does not visit within 1 month, the effects of the arctic dreams end.

Create Wendigo (Su)

By using wind walk with a creature or by affecting it with his unspeakable presence, Ithaqua afflicts the creature with an enhanced version of wendigo psychosis.

Wendigo Psychosis: Curse—unspeakable presence or wind walk; save Will DC 36; onset immediate; frequency 1/hour; effect 1d6 Wis drain (minimum Wis 1). When a victim’s Wisdom reaches 1, it seeks an individual of its race to kill and devour.

After completing this act, the victim takes off at a run, and in 1d4 rounds sprints up into the sky at such a speed that its feet burn away into jagged stumps. The victim transforms into a wendigo over the next 1d4 minutes. Once the transformation is complete, the victim is effectively dead, replaced by a wendigo. Miracle, true resurrection, or wish can restore such a victim to life, yet doing so does not harm the new wendigo. The save DC is Charisma-based.


Environment any cold
Organization solitary (unique)
