You attempt to interrupt a creature in the process of Casting a Spell. If the creature is Casting a Spell of 3rd-Level or lower, its spell fails and has no effect. If it is Casting a Spell of 4th-Level or higher, make an Ability Check using your Spellcasting Ability. The DC equals 10 + the Spell's Level. On a success, the creature's spell fails and has no effect.
At Higher Levels: When you cast this Spell using a Spell Slot of 4th-Level or higher, the interrupted spell has no effect if its level is less than or equal to the level of the Spell Slot you used.
You touch a willing creature. The target gains a Flying Speed of 60 feet for the duration. When the spell ends, the target falls if it is still aloft, unless it can stop the fall.
At Higher Levels: When you cast this Spell using a Spell Slot of 4th-Level or higher, you can target one additional creature for each Slot Level above 3rd.
You create the image of an object, a creature, or some other visible phenomenon that is no larger than a 20-foot cube. The image appears at a spot that you can see within range and lasts for the duration. It seems completely real, including sounds, smells, and temperature appropriate to the thing depicted. You cannot create sufficient heat or cold to cause damage, a sound loud enough to deal thunder damage or deafen a creature, or a smell that might sicken a creature.
As long as you are within range of the illusion, you can use your Action to cause the image to move to any other spot within range. As the image changes location, you can alter its appearance so that its movements appear natural. For example, if you create an image of a creature and move it, you can alter the image so that it appears to be walking. Similarly, you can cause the illusion to make different sounds at different times, even making it carry on a conversation, for example.
Physical interaction with the image reveals it to be an illusion,
because things can pass through it. A creature that uses its Action to examine the image can determine that it is an illusion with a Successful Investigation Check against your Spell Save DC. If a creature discerns the illusion for what it is, the creature can see through the image, and its other sensory qualities become faint to the creature.
At Higher Levels: When you cast this Spell using a Spell Slot of 6th-Level or higher, the spell does not require Concentration.
