Edit: I updated the range of the Lasso of Truth on the advice of a few folks. Sorry if people are disappointed. You can always adjust it as you see fit in your own game.
A few days ago I saw a short clip of Wonder Woman using The Lasso of Truth in her upcoming movie. Wonder Woman has some of the coolest gear in all of the superhero world! She has an invisible jet (I think it is great and I don’t care what anyone else has to say on the matter), bracelets that can deflect bullets, a variety of Amazonian weapons, an of course a magical lasso capable of forcing anyone to tell the truth. After seeing the video I immediately wanted to create a Dungeons & Dragons version of it.
Creating it was a bit difficult though, I mean this is an item forged by a literal god and used by one of the most powerful heroes in all of history. I took a look at the Rope of Entanglement in the Dungeon Master’s Guide, but that just wouldn’t do so I went back to the drawing board.
I know some people will say it is too powerful, but you know what? In my mind it SHOULD be super powerful. Anyway I hope some people like this, and maybe it will find a home in some D&D games.
The Lasso of Truth
Legendary item (requires attunement)
This Lasso of Truth is infinitely long extending itself as the user wishes, but only weighing 15 pounds. Any creature bound by Lasso of Truth is compelled to speak only the truth, and will answer any questions imposed on it to the best of its ability. If you hold one end of The Lasso of Truth you can make an attack using your Dexterity, on a hit the target is restrained by it. The effective range of the Lasso of Truth is 80 ft./160ft. As an action you can extend the rope an additional 15 feet.
You can release the creature by using a bonus action. A target restrained by the rope can use an action to make a DC 25 Strength or Dexterity check (the target’s choice). On a success, the creature is no longer restrained by the rope. As an action you can also fling a bound target dealing 2d12 + your Strength modifier bludgeoning damage.
Creatures vulnerable to radiant damage are incapacitated while bound by The Lasso of Truth.
Forged by Hephaestus himself he Lasso of Truth is unbreakable, only a true denial of the truth or a god/goddess of deception might prove capable of destroying it.
The Lasso of Truth provides bright light source in a 5 foot vicinity.
