A 5-ft-diameter Sphere storm cloud appears in a space of your choice within range and lasts for the Duration. Any creature that ends its turn within 5 ft of the Sphere must make an INT saving throw. A creature with an INT score of 2 or lower can't be affected by this spell. The creature takes 2d4 phychic damage on a failed save, or half as much damage on a successful one.
After a failed save, a target has clouded thoughts for 1 minute. During that time, it subtracts a d4 from attack rolls, ability checks, and CON saving throws to maintain concentration. The target can make an INT saving throw at the end of each of its turns, ending the effect on a success.
As a Bonus Action, you can move the Sphere up to 30 ft. If you ram the Sphere into a creature, that creature takes 2d4 phychic damage, must make an INT saving throw, and the Sphere stops moving this turn. If the target has already had clouded thoughts within the past minute, they are immune to the spell effect.
At Higher Levels: When you cast this spell using a spell slot of 3rd Level or higher, the damage increases by 1d4 for each slot level above 2nd. At 4th Level the clouded thoughts increase by 1d4 for every TWO slots above 2nd.
