The Fiend's Chain Binding

When you focus on a willing, or unconscious creature you create a magical flame looking chain bind that holds its hands together with similar binds appearing around its ankles. While bound, the creature has its speed reduced to 10 feet and cannot move more then 60 feet away from the caster. 

If the creature captive becomes conscious or unwilling, it can make a a Dexterity saving throw to break the binding.
