Conjure Chains

You summon magical, radiant chains out of thin air. They can be used as a far-reaching melee weapon or as a snare to grapple enemies. To attack, make a melee weapon attack against a creature within 30 feet of you. On a hit, the chains deal 6d8 radiant damage. If you attacked with the chain this turn, you may use your bonus action in an attempt to grapple (Strength Save against your spell-save DC) a creature you attacked. Your Spell Save DC receives a +5 bonus when a demon, undead, or devil makes a save against the chains. A target restrained by the chains cannot cast spells or activate special abilities. Once per turn thereafter, you can use your bonus action to tighten the chains, doing 2d6 bludgeoning damage and 1d6 radiant damage. The grappled creature can try the save once again at the end of each of its turns. This spell ends after 30 minutes, unless it is re-cast.
