You create a magical zone that infiltrates the mind of all creatures in a 15-foot-radius sphere centered on a point of your choice within range. Creatures that can't be charmed are immune to this effect. Until the spell ends, the caster can ask a creature within the spell's area to truthfully answer a question or instead perform a task of the caster's choosing. The target creature can make a Charisma saving throw, and can refuse the request on a success. On a failed save, it must choose either "truth" or "dare." 

If the target selects "truth," it must answer the question and must do so truthfully. An affected creature is aware of the spell and can thus be evasive in its answers as long as it remains within the boundaries of the truth. If the target selects "dare," the caster can command it to perform a simple task (limited to a sentence or two) as long as the task doesn't pose the risk of serious bodily harm, at the DM's discretion. The target must perform this task to the best of its ability until the task is completed or until this spell ends.  

If you or any of your companions damage the target, the spell ends.
