You tell the story of the Queen of Bees and her retinue trying to pass through a rainbow on their way to visit the King of Spiders. You conjure forth a large, transparent rainbow. Creatures who enter or begin their turn in the rainbow's space must succeed at a Fortitude saving throw or become Dazzled for 1 round (or Blinded for 1 round on a critical failure).
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.
An action with this trait requires a degree of mental concentration and discipline.
An effect with this trait depends on language comprehension. A linguistic effect that targets a creature works only if the target understands the language you are using.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
