Range: 30 feet
Components: V, S, M (an item distasteful to the target)
Duration: Concentration, up to 1 minute

Inactive. You can't take any action, Bonus Action, or Reaction.
No Concentration. Your Concentration is broken.
Speechless. You can't speak.
Surprised. If you're Incapacitated when you roll Initiative, you have Disadvantage on the roll.

. At the end of each of its turns, the target can repeat the save, ending the Spell on itself on a success. When the Spell ends on the target, it reappears in the space it left or in the nearest unoccupied space if that space is occupied.

If the Spell lasts on the target for 1 minute and the target is an Aberration, a Celestial, an Elemental, a Fey, or a Fiend, the target doesn't return. It is instead transported to a random location on a plane associated with its Creature Type.

At Higher Levels: When you cast this Spell using a Spell Slot of 5th level or higher, you can target one additional creature for each slot level above 4th.
