this is a small summary of what I have gathered about dupes over the years - some may be wrong, but I think it's a decent idea of how it works.
Items poof when they are matched with an item with an identical item code on the same server.
Legit = really did drop, won't ever poof
Perm = duped, but either doesn't have an item code to clash (items that were duped as whites) or was duped before patch 1.10 (or maybe pre-09... not sure). These old dupes were allocated their own legit item codes during the patch, hence they wont ever poof unless blizzard goes through and specifically deletes them.
Unperm = duped, and has the same item code as another item on the realm, or imported (has an invalid item code i guess). These items will poof if the passive ruststorm catches an item code match on the server at the same time. Hence why you can never really be sure that an item is perm - it's entirely possible the only a few copies of an item (or an item with that exact item code) were made, and if you're not online at the same time as these other copies, your one won't poof.
For example, you may trade for a Zod in game. It may be unperm, but if there are only 10 other copies of that specific Zod, and they are all on mules that are inactive, then your one won't poof. you could think it is legit, until some time months down the track when you just happen to be online as someone else revives their mule and joins a game with their dupe of the zod at the same time as you are playing.
I've known items to poof after 6+ months of solid use because the item was such an uncommon dupe that it simply did not clash at any time in that period.
quoting myself
also, on temp perming:
Quote (Pikaberdot)
I know that most of you already know the temp-perm method(s), and use them frequently to save your dupes (ie, avoid the dupe scanner).
This is for those of you who do not.
The temp-perm methods will only allow you to keep your dupes for THAT game (that you did the temp-perm in). You MUST repeat every game where someone MAY possess the same dupe as you, in order for your dupes to never disappear.
If you have any questions/comments, PM me.
The Temp Perm Methods:
First Method (safest)
1.) Open a trade window with anyone who DOES NOT have any of the same dupes you are trying to perm.
2.) Put your duped item(s) you want to perm in the trade window.
3.) Save+Exit immediately after, before anybody else who has a possibility of having one of the same dupes as you leaves.
4.) The above will work everytime, just don't forget to do it every game to be safe.
Second Method (bit more risky) Make sure your item doesnt have a socket because the NPC will not sell it back.
*Make SURE you have a LOT of gold before you do this, and the NPC you are selling your dupe(s) to has space in their inventory.
1.) Go into a trade or trade/repair window with any NPC (Charsi/Akara for example) and sell your duped item(s).
2.) Buy it back
3.) Save+Exit the game immediately after, before anybody else who possibly has the same dupe(s) as you can leave.
*You might wonder why you would want the 2nd method... Well here's an Example Scenario:
You and a friend were in a game transferring. You had an .08 Arkaine's and so did your friend who saved+exited and said "thanks for the transfer, I gotta go." You are stuck there.. If you save+exit you lose your Valor. You look @ your friend list, nobody is on, you call your friend, he's not home... It's a private game, so nobody else can join. Wait a second! You know how to temp-perm without having a 2nd person to do it with! Dilemma Solved.
*How the methods keep the dupes from deleting (very basic explanation):
Both methods outlined above will cause the item ID to go up by ONE, temporarily, and will be reset to their actual ID as soon as you join your next game. The dupe scanner works by detecting two of the exact same item ID's in the same game, and deleting the last one that saves+exits the game with the same ID. If you change the ID by one temporarily through the methods above, the dupe scanner doesn't see your item as being a dupe, or the person who might've left before you, if they had the same dupe(s).
If you want to see how it works, you can use d2hackit, and sniff the packets of the item ID before you do a temp-perm method, and after. The last # will go up by one. (Example: Your 08 gaze's ID was: 04 00 02 03, after a temp perm it will change to:
04 00 02 04, and the next game you join, it will be 04 00 02 03 again.
Tips to remember about the dupe scanner (what items can't delete)
Currently in the 1.09d patch, the following items are NOT being detected by the dupe scanner, thus cannot be deleted, and do NOT need to be permed:
Any NON-MAGICAL item. This includes socketed items without another mod (ie, not jeweler's or of the whale, etc.). Most ed/ias and ed/max armors are non-magical, and will NOT be picked up by the dupe scanner.
Any RUNE WORD or ITH item. These are considered as non-magical items by the dupe scanner.
*IMPORTANT NOTE: DO NOT TRY AND SELL ANY RUNE-WORD TO AN NPC, AS YOU CANNOT BUY THEM BACK, REGARDLESS IF THEY HAVE ROOM OR NOT.
Any pre 1.08 (classic items). This includes most (99%) of SOJS, Godly Rares (like Corruption Grips, Raven Spirals, Soul Spurs, Rune Slippers, Soul Shanks, etc.).
Rumors
1.) Despite what anybody tells you, the dupe scanner DOES detect duped items on a merc and will delete them, even if the merc is dead.
2.) Personalizing/Socketing an item will NOT have any affect on the dupe scanner deleting/not deleting the item.
I hope this helps some of you who were unclear on how the dupe scanner works or temp-perming.
old, yes, but probably still valid (at least on how temp perming works)
