Stridulating Song
Frequency once per day
Effect You circulate magic through your wings, causing them to vibrate at high speeds such that their scraping produces disruptive sounds. You focus the sound at one creature within 30 feet who must succeed at a fortitude save against your class DC or spell DC (whichever is higher) or become Sickened 1, or Sickened 2 on a critical failure, as the vibrations disrupt its inner equilibrium. You can Sustain the effect for up to 1 minute; the creature can't recover from the sickened condition as long as you continue your song and it can hear you.
Traits
Auditory actions and effects rely on sound. An action with the auditory trait can be successfully performed only if the creature using the action can speak or otherwise produce the required sounds. A spell or effect with the auditory trait has its effect only if the target can hear it. This applies only to sound-based parts of the effect, as determined by the GM. This is different from a sonic effect, which still affects targets who can't hear it (such as deaf targets) as long as the effect itself makes sound.
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
