A heap of insults and invectives spew from your mouth—words so devastating your foes burn from the intensity of your diatribe. Your words deal 2d6
persistent fire damage, and the target must attempt a Will save. If the target doesn't understand the language or you're not speaking a language, it gains a +4 circumstance bonus to its save.
Critical Success The target is unaffected.
Success The target takes half the persistent fire damage.
Failure The target becomes
frightened 1 and takes the full persistent fire damage.
Critical Failure The target becomes frightened 2 and takes double the persistent fire damage.
Heightened (+2) You can target two additional creatures, and the persistent damage increases by 2d6.
