[RPG] Can the Dominate Person spell be used for interrogation

dnd-5einvestigationspells

If you capture a foe and cast dominate person on them, will they then truthfully answer any questions you ask them, such as where their base is located, what secret entrances it has, the password of the day, and so on?

Best Answer

I think you could.

You can use this telepathic link to issue commands to the creature while you are conscious (no action required), which it does its best to obey. You can specify a simple and general course of action, such as “Attack that creature,” “Run over there,” or “Fetch that object.”

Since you are charming the creature and it follows your instructions, but appears to still be conscious and aware rather than a mindless slave, I think that you could ask it questions and it would answer them as to the best of its ability. Its up to the DM whether it tries to please you and be helpful or is only compelled to meet the minimum of the request.
