Whisper of the Leucrotta

You utter the growling and whispering curse of a leucrotta targeting a creature within range. If the creature can hear you, it must succeed on a Wisdom saving throw or become Cursed for the duration. While cursed, the creature loses its voice and cannot speak, yell, cast spells with vocal components, or otherwise use its voice. At the end of each of their turns they can remake the initial saving throw, ending the curse upon success. If a creature dies while affected by this curse, you gain the ability to perfectly mimic the creature’s speech.
