Combat

Unicorns normally attack only when defending themselves or their forests, They either charge, impaling foes with their horns like lances (see Charge, page 124 in the Player's Handbook), or strike with their hooves. The horn is a +3 magic weapon, though its power fades if removed from the unicorn.

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 use 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.

Immunities (Ex): Unicorns are immune to all poisons and to charm and hold spells or abilities.

Skills: Unicorns receive a +3 competence bonus to Survival checks within the boundaries of their forest.
