Void Gaze

You create a window through to the Void in the air inside a 30-foot cube within range. For a moment the full manifestation of the Void appears and terrifies all who look upon it. Each creature in the area who sees the Void window must make a Wisdom saving throw. On a failed save, the creature becomes frightened for the duration. While frightened by this spell, the creature is incapacitated and has a speed of 0. A creature who serves the Void (Cleric or Paladin of the Void), or who has been Blessed by Void (Bless spell cast by Void Cleric), has advantage on the saving throw.

The spell ends for an affected creature if it takes any damage or if someone else uses an action to shake the creature out of its stupor.
