This spell causes the feathers of a willing creature with a fly speed to emit pulses of light that other specific sorts of creatures find almost irresistibly intriguing. The caster must designate a particular type or subtype of creature as susceptible to these pulses at the time of casting. Creatures normally immune to mind-affecting effects, or those who lack the ability to see, are not vulnerable to this spell. Any eligible creature belonging to the category established by the caster that comes within 30 feet of the target and has a clear line of sight must make a Will saving throw to avoid becoming fascinated. Fascinated creatures follow the target if it moves away and remain under its influence so long as they can continue to see it and stay within 90 feet of it.

Animals and similar creatures only stay within sight of those they have fascinated if specifically trained to do so.
