You shroud the mind of a creature you can see within range in shadow, twisting their view of the world around them.
Everything more than 15 feet from the target becomes wreathed in shadow and indistinct noises, distorting how they perceive it. If the target attempts to target a creature wreathed in shadow in this way with an attack or spell, it must pass a Wisdom saving throw, or it instead targets a random different target within range. When the target creature becomes able to see a creature that was previously wreathed in shadow, it must pass a Wisdom saving throw, or become frightened of that creature until the start of its next turn.
At the end of each of the creatures turns, it makes a Wisdom saving throw. On failure, the shadows draw 5 feet closer, closing off the distance the target can see clearly. If the target's entire vision becomes shrouded with shadows (after making 3 failures), they become paralyzed with fear until they pass the saving throw against the spell. If the target passes their saving throw, the spell ends.
