Volta's Spectral Beast

You touch one willing Creature and cause an Illusion of a Large or smaller Beast of your choice to encompass it for the duration. Until the Spell ends, the Target can take a Magic Action to force a Creature within 60 feet of it to make a Wisdom Saving Throw. On a failed save, the Creature is unable to willingly move closer to the Spell Target until the end of its next Turn. A Creature automatically succeeds on this save if it can neither see nor hear the Spell Target, or if it's Immune to the Frightened Condition.
