Immunities: Unicorns are immune to all poisons and to charm and hold spells.
Iron Vulnerability (Ex): The mere touch of iron (including steel) deals 1 point of damage to an unseelie fey. A hit with an iron or steel weapon deals an additional +1d6 points of damage.
Low-Light Vision: The creature can see twice as far as a human in starlight, moonlight, torchlight, and similar low-light conditions.
Magic Circle against Evil (Su): This ability continuously duplicates the effects of the spell. The unicorn cannot suppress this ability.
Spell-like Abilities: Unicorns can detect evil at will as a free action. Once per day a unicorn can teleport without error to move anywhere within its home. It cannot teleport beyond the forest boundaries nor back from outside.
A Unicorn can use cure light wounds three times per day and cure moderate wounds once per day, as cast by a 5th-level druid, by touching a wounded creature with its horn. Once per day it can use neutralize poison, as cast by an 8th-level druid, with a touch of its horn.
Winter's Chill (Su): An unseelie fey with winter chill has a presence that disquiets non-fey. The more beautiful the creature is, the more uncomfortable other beings feel. Living, non-fey creatures within 5 feet of her feet uneasy and suffer a -6 morale penalty on saves.
Skills: *Unicorns receive a +3 competence bonus to Survival checks within the boundaries of their forest.
Unseelie unicorns are hostile and dangerous creatures. They usually attempt to trick or attack those they encounter.
