Spell-Like Abilities: Pegasi can detect good and detect evil at will within a 60-yard radius, as the spells cast by a 5th-level sorcerer.

Skills: Pegasi receive a +4 racial bonus to Listen and Spot checks.

Pegasi attack with their sharp hooves and powerful bite. Mated pairs and herds attack as a team, fighting to the death to defend their eggs and young, which fetch a handsome price in many civilized areas.
