Spell description

When you cast Zone of Truth, you pick a point within a range of 60 feet. Around that point, a zone of 15 feet in radius in the form of a sphere is formed. Inside this sphere, deception is guarded against. 

For the duration, any creature inside or that enters the sphere must make a CHA saving throw at the start or the first time of the turn.

  • Failed throw: if the creature fails to throw, the creature can no longer tell deliberate lies.
  • Successful throw: there is no effect on the creature. 

Both you and the target are aware of the spell being cast and whether it has failed.

Zone of Truth’s advantages and drawbacks


  • No materials needed: It is no secret that I enjoy the magic that does not require a material component. Therefore, you don’t need to spend any of your gold pieces or have to think about getting materials. 
  • Fun for creative players: If you enjoy the role-playing aspect more than hacking and slashing and swords and sorcery, then a spell-like Zone of Truth can be pretty fun to use. Both as a Dungeon Master and a Player. 
  • Know when someone hides info: A PC or NPC is not forced to tell the truth, so they can keep their mouth shut to avoid lying. However, by doing so, they are making clear that there is something they do not want to answer truthfully. 


  • No deliberate lies: You can’t get the right information if the one you are asking thinks what he is telling is the Truth. It can be quite dangerous to rely on Zone of Truth for your info. As you will probably assume, what is being said is true, while it can be wrong. 
  • No compulsion to talk (!): Many players and even DMs skip over the part where the creature knows that it has been enchanted and can just stay quiet if it doesn’t want to say a word.

Best uses for Zone of Truth 5e

1. Combining Zone of Truth with Speak with Dead 

Did your party go ham again, and did the suspect lose his life due to a slightly misplaced Tidal Wave? Well, no worries. A couple of spells might help you out of your predicament when using Speak with Dead to interrogate death. Zone of Truth is an excellent way to ensure you get more information from them and know who is hiding something from you.

2. Filtering suspects 

If there has been a murder, a robbery, or you want to know who is behind evil plans, you will often have to start being a detective and figure out clues. However, Zone of Truth can be a fast and effective brute force interrogation tactic. 

Yes, your guy isn’t forced to talk to you. However, you can learn quite a lot from what your suspects are not saying. Gather a group of suspects and put them in the radius of the Zone of Truth. Everyone who can answer your questions is free to go; those who refuse to talk should get a more enhanced interrogation. 

3. Buying items from sneaky merchants

Not in the mood to get ripped off? Use Zone of Truth before making your next big armor purchase. You won’t be walking away sorry if you know what item is the best quality and is worth the money. You can also find out what Merchants offer the best items for the best price or simply ask them what the lowest price is they are willing to go.
