Divine Chains

Dvine Chains wrap around a target. The target must make a dexterity saving throw against the caster's spell DC. On a failed save the target is restrained. On the caster's turn they can use a bonus action to cause the chains to flare up and cause 1d6 radiant damage to the restrained target. The target is restrained until the spell ends, the spellcaster loses concentration or the target takes necrotic damage.

At Higher Levels: For each level above 2nd, an additional creature can be targeted. And an extra d6 is added to damage. When two or more creature's are grappled the radiant damage can be distributed between targets as the caster wishes.
