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.

This effect alters a creature’s emotions. Effects with this trait always have the mental trait as well. Creatures with special training or that have mechanical or artificial intelligence are immune to emotion effects.

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.

A mental effect can alter the target’s mind. It has no effect on an object or a mindless creature.
