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.
Actions with the flourish trait are special techniques that require too much exertion for you to perform frequently. You can use only one action with the flourish trait per round.
A mental effect can alter the target's mind. It has no effect on an object or a mindless creature.
