You steal a creature's voice, rendering them mute. The effect is determined by the target's Fortitude save. The target then becomes temporarily immune for 1 minute. A creature that has no voice or can't speak is immune to this spell.
Critical Success The target is unaffected.
Success The target becomes voiceless until the end of its next turn. A voiceless creature can't speak, create vocal sounds, or take auditory actions (including supplying verbal or command components). As long as the target is voiceless, whenever you speak, you can choose to have your voice sound like either your voice or the target's voice.
Failure As success, but the duration is 1 minute.
Critical Failure As success, but the duration is permanent.
Traits
An action with this trait requires a degree of mental concentration and discipline.
A curse is an effect that places some long-term affliction on a creature. Curses are always magical and are typically the result of a spell or trap. Effects with this trait can be removed only by effects that specifically target curses.
An ability with this trait can take a character completely out of the fight or even kill them, and it's harder to use on a more powerful character. If a spell has the incapacitation trait, any creature of more than twice the spell's rank treats the result of their check to prevent being incapacitated by the spell as one degree of success better, or the result of any check the spellcaster made to incapacitate them as one degree of success worse. If any other effect has the incapacitation trait, a creature of higher level than the item, creature, or hazard generating the effect gains the same benefits.
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.
