Eldritch Binding

You summon forth dark chains, bursting forth from you, attempting to bind a target. One creature of your choice within range must succeed on a Dexterity saving throw against your spell save DC or take 3d6 force damage and become restrained, taking half as much damage with no additional effects on a successful save.

While the target is restrained, you can use a bonus action to force move the creature 10 feet closer to you. They can also use an action on their turn to attempt a Strength saving throw against your spell save DC, to break free from the chains. Additionally, while the target is restrained, you can move freely while concentrating on this spell, though attempting to move further than 30 feet from the target will end the spell early. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can target an additional creature for each slot level above 2nd.
