Frigid Grasp

You conjure 2 orbs of unnaturally cold ice and hurl them at targets within range. You can hurl them at one target or several. Make a ranged spell attack for each orb. On a hit, a target takes 2d4 cold damage, and if the target is a creature that is large or smaller, it must succeed on a Strength saving throw or be restrained by magical ice until the end of your next turn. A creature cannot be forced to make this saving throw more than once per casting of this spell, and a creature does not make this saving throw if it is already restrained by this spell. If an unoccupied liquid is hit by this spell, a 5-foot cube of the liquid, centered on the point of impact, freezes solid for the spell's duration. 

At Highr Levels. When you cast this spell using a spell slot of 3rd level or higher, you create one additional orb for each slot level above 2nd.
