Spell: Croak Voice
You cause the target creature's vocal chords to swell like those of a frog. The target must attempt a Fortitude save.
Critical Success The target is unaffected.
Success The target's voice becomes hoarse, and speaking becomes painful. Whenever it uses an action that has the auditory trait or attempts to Cast a Spell that doesn't have the subtle trait, it must succeed at a DC 5 Flat or the action is lost. Once per round, the target can spend an Interact action to massage its throat, attempting a Fortitude save against your spell DC. On a success, the spell ends.
Failure As success, but using an action with the auditory trait also deals 2d10 mental damage to the target as the sound of its distorted voice grates on its ears.
Critical Failure As failure, but the damage for using an action with the auditory trait is doubled, and the target can't use an Interact action to attempt a Fortitude save to end the effect early.
Heightened (+1) The damage for using an action with the auditory trait increases by 1d10.
