Binding Chains

You summon chains of magical force in an attempt to prevent a creature from leaving its position. Make a ranged spell attack against the target creature, on a hit the target is restrained for the duration. A restrained creature can use an action to make a Strength(Athletics) check against your spell save DC to end the effect on a success.
 
If the target creature triggers this effect by casting a spell, the spell fails and has no effect.
