Demoralizing Stanza

You unleash a string of demoralizing words with subtle enchantments at a creature you can see within range. If the target can hear you (though it need not understand you), it must succeed on a Wisdom saving throw or subtract a d6 from the next attack or saving throw (chosen at time of casting) made before the start of your next turn.

At Higher Levels: This die being subtracted increases. It becomes a d8 at 5th level, a d10 at 11th level, and a d12 at 17th level.
