DM's: If you want your main villain to have some privacy from pesky adventurers while going about their evil scheme, have them purchase one of these. :)

Likely should extend that comment to more than just villains. Rulers, diplomats, spies, religious leaders, thieves guild leadership, business leaders, all would have a reason to fork over the gold for this sort of item. It does bring up questions of if only the user not visible to divination magic or does it create a small imperceptible zone around a user. If two characters are having a conversation, one has an amulet and the other does not, can half the conversation still be heard or seen. The answer should be a DM decision of course. An amulet that creates a 20 ft. sphere of no detection would be more rare and powerful compared to an amulet that only masks the wearer, so there is room for scaling as needed.

Perfect for a pc in my group. She is trying to avoid her demon worshipping family whi are trying to track her down to use as a sacrifice. Might have to do a hime brew to search for this and get it tuned to her. 

I can imagine a guild of wizards who specifically sell nothing but these amulets going from town to town selling to nobles, paranoid merchants, and thieves. 

I can also imagine another snake-oil salesmen selling fake versions of these amulets!  That could be an interesting hook, come to think of it....

Does this item prevent a target from being targeted by any Divination magics, even Detect Magic or Gift of Alacrity?

Seconding this question, it has been bothering me for awhile. 

So kinda weird interaction, the amulet states you are "hidden" and "cannot be targeted" by Divination Magic. Tongues is Divination, so does that mean you can't have Tongue cast upon you by anyone while attuned to this? Just kinda a weird wording thing that might be pertinent at some point.

yes it blocks even beneficial divination magic from targeting you.

I just ignore the effect when dealing with beneficial divination magic

That is the straightforward reading of the spell.  A character wearing this item cannot be the target of any spell in the Divination school, even if it's a beneficial spell like Guidance, Foresight, or Telepathic Bond.

It's less obvious that "you are hidden from divination magic" is intended to have mechanical consequences for people who are not declared "targets" of a spell but may be revealed by a spell.  If someone else casts True Seeing on himself, can he see an invisible character who is wearing this item?  According to the logic of this Jeremy Crawford tweet about the identically-worded Nondetection spell, this amulet protects the wearer from being perceived by Divination magic like See Invisibility even if the wearer is not a declared target.

That suggests to me that a character under the effects of Foresight, Guidance, or Fortune's Favor would gain no benefits in combat, contests, or ability checks against a character wearing this item.  Narrating how those spells failed would be fun.

Good use of this could be a family who is haunted by Devils or Demons and use for a way to hide. One night, a Devil steals the Amulet and you must retrieve it! I actually use this for one of my campaigns which involves a King, Queen and a Prince of Lizardfolk who needs the Amulet back.

I want to say that True Seeing would still work, but it's debating technicalities. His quote (for those who don't want to follow the link) says:

"The nondetection spell hides you from divination magic. True seeing is a divination spell."

This would imply that Nondetection whilst invisible indicates True Seeing would not find you. If that's the case, then I think this item and the equivalent spell (to a lesser degree) are somewhat overpowered.

If you can go invisible and are impossible to spot by any means, then that's a huge advantage to the user. You could still be detected by any creature that has natural Truesight, however. Personally, I'm of the opinion that for True Seeing, you're not spotting the invisible creature using Divination, but by a sense (Truesight) that just happens to be granted by Divination magic.

Since creatures who have natural Truesight can still see you, I'm fine granting this ability to Divination-based Truesight just to keep the mechanics of the sense consistent. It's also a somehat niche circumstance where you'd need both nondetection and invisibilty active, whilst evading an enemy using True Seeing.

The other part is the description specifically says (a) the target can't be targeted by any divination magic; or (b) perceived through magical scrying sensors. It doesn't technically cover being perceived using effects from spells like True Seeing, only Scrying sensors. Although the complication there is that opens up all sorts of problems, like See Invisibility. This spell technically falls within the rules since the invisible person isn't the "target" of the spell, nor is it the target of a Scry.

So for me, I'm inclined to take the definition literally. Any spell where the target is under the effect of nondetection or wearing this amulet will fail. Everything else is fair game. If using that definition this essentially means:

- any Divination spell that isn't a target of Self will fail if used against a target under this effect; and
- If you attempt to use a Divination spell with a target of Self while you yourself are under this effect, it will fail.

So technically, you or any of your party wearing this amulet will cause your beneficial Divination spells to fail. The exception here is Scrying, which is a target of Self but the 2nd effect description covers that.

Dude this is a god item let me explain. if there was a trap that was triggered (with magic) if you went into the room with this you would be immune to it.

Ah yes, the Amulet of Proof Against Detection and Location. Or, as I like to call it, the Caleb Widogast Amulet.

In our campaign, we found an ancient stone box in an ancient, forgotten shrine to Helm that gives us an item that could be useful for what is to come every now and then. (It’s usually empty.) My bard recently passed the box to our warlock-sorcerer who’s being fought over by a deva and Titania herself, and this amulet is what came out of the box for them. I recognized it immediately from the description alone thanks to Critical Role!

This does NOT protect you from the Detect Sentience feature of Intellect Devourers, by the way it is written. Detect Sentience says it is thwarted only by Mind Blank, and it is also not a spell. 

How do you identtify this item?  Does it only protect the wearer from being targeted by Divination? Or is the item itself unable to be dvinened?  

If say, a cult carved an arcane rune on a character to detect when they enter certain places or speak/write certain knowledge, does this block them from detecting the character?

Would Brand of Castigation from Blood Hunter still work even with this?

 It only protects the wearer. The item itself RAW (since it specifies the wearer) would still be picked up by detect magic or identify. Items that aren’t traditional or have untraditional mechanics with identifying will be written, most likely in the item description or PHB/DMG, such as how curses can’t be identified.
