A gaze attack takes effect when opponents look at the creature’s eyes. The attack can have almost any sort of effect: petrification, death, charm, and so on. The typical range is 30 feet, but check the creature’s entry for details. The type of saving throw for a gaze attack varies, but it is usually a Will or Fortitude save. The DC is equal to 10 + 1/2 gazing creature’s HD + gazing creature’s Charisma modifier (the exact DC is given in the creature’s Species Traits). A successful saving throw negates the effect.
Each opponent within range of the gaze attack must attempt a saving throw each round at the beginning of his or her turn. Opponents can avoid the saving throw by averting their eyes or by using a barrier to sight.
Averting One’s Eyes: The opponent avoids looking at the creature’s face and instead looks at its body, watching its shadow, tracking it in a reflective surface, or the like. Each round, the opponent has a 50% chance to not need to make a saving throw against the gaze attack. The creature with the gaze attack, however, gains one-half concealment against that opponent.
Barrier to Sight: An opponent that cannot see the creature at all cannot be affected by its gaze attack. This can be accomplished by turning one’s back on the creature, shutting one’s eyes, or wearing a blindfold or head covering that prevents sight. The creature with the gaze attack gains total concealment against the opponent.
A creature with a gaze attack can actively gaze as an attack action by choosing a target within range. That opponent must attempt a saving throw but can try to avoid the gaze as described above. Thus, a target may need to save against a creature’s gaze twice during the same round: once before the target’s action and once during the creature’s turn.
A creature is immune to its own gaze attack unless otherwise noted.
