Astor's Lasso

You whirl a glowing magical lasso and cast it toward one creature you can see within range. The target must succeed on a Dexterity saving throw or become Restrained for the duration.

A creature Restrained by this spell can take an action to make a Strength (Athletics) check against your spell save DC. If it succeeds, it is no longer Restrained.

Golden Lasso. If you cast this spell using gold dust worth at least 100 gp, which the spell consumes, the lasso becomes radiant gold and sheds Bright Light in a 20-foot radius and Dim Light for an additional 20 feet. The creature Restrained by the lasso must succeed on a Charisma saving throw. On a failed save, it can't speak a deliberate lie for the duration. You know whether a creature succeeds or fails on this save. An affected creature is aware of the spell's affect and can avoid answering questions to which it would normally respond with a lie. Such a creature can be evasive yet must be truthful.
