You overwhelm your target's senses as you rewire them in unexpected ways, causing them to process noises as bursts of color, smells as sounds, and so on.

The target must make a Intelligence saving throw, potentially receiving the following three effects, and even potentially being

Stunned

• Due to the distraction, the target must succeed at a DC 5 flat check each time it tries to use an action that requires concentration, or the action fails and is wasted.
• Due to the target's difficulty processing visual input, it must succeed on a DC 5 flat check when targeting any creature or object.
• The creature has trouble moving, making it
  Clumsy
  and reducing its speed by 4m.

Critical Success (+10). The target is unaffected.
Success. The target is affected until the end of its next turn.
Failure. The target is affected for 1 minute.
Critical Failure (–10). As failure, and the target is Stunned until the end of its next turn.

Once per turn, a creature can use its action, or its movement and bonus action to attempt an Intelligence check against your spell save DC. On a successful check, this spell ends on that creature.

At Higher Levels: You can target one extra creature for each spell level increase. These extra creatures must be within 6m of the original target.
