An ultraviolet green ball of writhing baby arms and neon pink spiders strobe forth from your middle finger to a point you choose within range and then invade the mind with a rising chorus of anguished screams ending in an explosion of pulsating purple tentacles and yellow-green flame teeth heralding the impending mastication of all existence. Each creature in a 30-foot-radius triskaidecagon centered on that point must make a Wisdom saving throw. A target takes 7d6 psychic damage on a failed save, or half as much damage on a successful one.
The tentacles spread around corners. All affected intermittently feel the crawl of spiders until a good bath or a long rest.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
