New Spell: Crow Storm

Version 3.0
Sorcerer, Wizard 3rd-level Illusion Casting Time: 1 action Range: Self (15-foot burst) Components: V, S, M (a crow’s feather, beak, or talon) Duration: Concentration, up to 1 minute   You teleport 15 feet away.
-At your original location, you leave behind an illusory double for the duration or while you maintain concentration. Around this double is a 15-foot diameter projection of a phantasmal image of a murder of crows flocking and flying about you. While you maintain concentration on this spell, the crows flap, squawk, and caw all around you. A creature caught in the area during the first round of its duration must make a Wisdom saving throw. -On a successful save, they see through the illusion, its image remaining as a transparent outline. On a failed save, the creature spends its action swatting away the illusory crows. -On subsequent turns, creatures that move into the radius or begin their turn inside the radius are affected by Light Obscurity as the crows fly about. Creatures are allowed a Wisdom saving throw at the start of their turn each turn they rtemain in the radius. On success, the illusion no longer obscures their vision and its image remains for the duration as a transparent outline. On a failure, the creature cannot take reactions or bonus actions for the remainder of their turn.
NOTE: This spell is based on D&D 5e's Mislead and Stinking Cloud and should be balanced as such.

Old Version, v2.0

Sorcerer, Wizard
3rd-level Illusion
Casting Time: 1 action
Range: Self (15-foot burst)
Components: V, S, M (a crow’s feather, beak, or talon)
Duration: Concentration, up to 1 minute
You teleport up to 30 feet in any direction to an empty space that you can see. You project a phantasmal image of a murder of crows flocking and flying about you. While you maintain concentration on this spell, the crows flap, squawk, and caw all around you. A creature that starts its turn in the area concentrating must make a Constitution saving throw or lose its concentration. Any creature attempting to attack someone with the radius of Crow Storm must make a Wisdom save. On a failure, any attack made against a target, except those made by you, within the illusion’s radius has disadvantage for that creature. On a success, the creature sees the crow’s as faint outlines wisping about you and does not suffer disadvantage and cannot have its concentration break. An attacker is immune to this effect if it doesn’t rely on sight, as with blindsight, or can see through illusions, as truesight.

NOTE: This spell is based off of 5e Player’s Handbook’s Blur and Misty Step and 5e Elemental Evils Player’s Companion’s Spell Warding Wind.
