About _NPCScan

_NPCScan tracks seldom-seen rare mobs by proximity alone, making the old “/targetexact …” macros obsolete. It has the same range as those targeting macros, but you won't have to mash any buttons. Just go about your business and let _NPCScan alert you when it finds something.

V5.x Changes
  • Due to changes in how the addon stores data, some settings might get reset when updating.
  • The default alert is suppressed while on flight paths by default. If a mob is found, the whisper sound effect will play and the mob & location will be placed in the chat log. You can turn this off from the settings.
  • _NPCScan now includes all rare mobs in the game.
  • The "One of Many", "Timeless Champion" & "Champions of Lei Shen" Achievements have been added.
  • Rare Mobs and Tameable Mobs have their own tabs now.
  • Custom mobs have been added for the Ghostly Pandaren Fisherman & Craftsman.
  • Individual mobs can be removed from their tabs to stop tracking them.

NPCScan now tracks "vignettes". These are the little skulls appear on the minimap, that denote rare mobs. This is a beta feature and is disabled by default. Enabling this feature will alert you to a rare that's within minimap range, without any worries about having to clear your cache. When you get an alert you will be shown a target button similar to the standard mob alert, letting you know that a vignette mob was detected. Clicking on the target button will try and target the mob. Once a mob is targeted, the target button will update to reflect the mob found.

Known Issues: Currently there is no way to detect what mob the vignette represents. Because of this there is no way to filter out and ignore individual mobs. The vignette tracking will ignore achievement mobs groups that have their tracking turned of via unchecking their tab. Also the targeting button might have some issues if there are more than one vignette mobs in target range.

The Cache

This addon doesn't use nameplates or mouseover units to find rares. Instead, it checks your creature cache for the moment a rare mob is found. There is one catch to this technique however: Once a mob is “found”, _NPCScan won't be able to find it again until your cache is clearedf you find a rare mob's corpse—Dirkee for example—you would have to clear your cache before _NPCScan would find Dirkee again. Thankfully, clearing your cache is a safe and simple matter.

Clearing Your Cache

To clear your cache, follow these straightforward steps:

  1. Exit World of Warcraft
  2. Delete the “Cache” sub-directory inside your World of Warcraft folder.  For example on a standard Windows XP installation, you would delete the folder “C:\Program Files\World of Warcraft\Cache”.
  • Advanced users can delete “C:\Program Files\World of Warcraft\Cache\WDB\enUS\creaturecache.wdb” specifically to improve log-in times, where enUS is your language code.

Note: Windows Vista and Windows 7 users see this info if your cache isn't in the location above.

That's it. Log in after you've done that and you'd be able to find Dirkee a second time. It's completely safe because WoW will recreate your Cache folder after you log in again.

Cache Warning

If a rare mob is already cached when you log in, _NPCScan will print a warning message with the names of those mobs. If you see this message but still want to find the listed NPCs again, it's time to clear your cache by following the above procedure; Otherwise, you can quit searching for those mobs using the Search options window detailed below. You can suppress this log-in message using the main options pane, as well.

“Found” Alert

When a rare mob is found, _NPCScan alerts you by playing a loud and distinctive sound, making your screen pulse red, and displaying an animated Targeting Button. To get a feel for what this alert looks and sounds like, try the “Test Found Alert” button in the addon's main Interface Options panel. (See the Options section below.)

Targeting Button

When clicked, the targeting button tries to target the most-recently-found mob.  You can also bind a key to hit this button. If the default button position isn't to your liking, you can move it while holding your CTRL key.

Note: The button cannot be shown during combat. In the unlikely case that you do find a rare while fighting, the button will appear after you leave combat. You will still hear the alert however, and the name of the mob will appear in your chat log.


_NPCScan's main options window can be accessed from the Interface Options menu. This panel includes a “Test Found Alert” button, various ways to customize the alert sound, and an option to suppress cache warning messages on log-in. New sounds can be added to the alert sound dropdown menu by installing SharedMedia-type addons.

Search List

The list of mobs that _NPCScan searches for can be modified easily through the Interface Options panel, however it comes pre-configured with most rare Outlands and Northrend mobs.; To access the mob list, type “/npcscan”. Grayed out NPCs in a list aren't being searched for, either because they're cached or not needed for their achievement.

The first tab available lists Custom NPCs that you can enter or remove manually. NPCs that are already cached show a red “X” in the first column. You can add or remove Custom NPCs with the [+] and [-] buttons at the bottom right.

All other tabs control achievements like Bloody Rareand Frostbitten. These tabs show an additional column on the right with green check marks for completed achievement mobs. You may enable or disable tracking each achievement with its tab's checkbox.

To remove non custom mobs from a tab, click on the mob that you want to remove and then click on the "Remove" button. This will remove the selected mob from the current tab and add it to the Ignore List Tab. If you ever want to restore a Ignored Mob, select it from the "Ignore List" tab, click the "Remove" button and it should be added back to its original tab.

The “Search for completed Achievement NPCs” checkbox at the top left of the pane allows you to keep looking for mobs you no longer need for achievements.

Finding NPC IDs

A mob's NPC ID is its unique identification number, and it can be found on sites like WowHead or WowDB For example, search for the mob “Dirkee” on WowHead and go to the mob's page.  That page's URL will look like

32500 is Dirkee's NPC ID.


The only problem mobs for _NPCScan are tamable beasts & Battle Pets. Whenever you run across the tamed version, _NPCScan gets tricked into thinking that mob is nearby. In order to prevent those false positives, _NPCScan only shows alerts for tamable mobs in their original zones That is, if you spot Loque'nahak in Dalaran instead of Sholazar Basin where it usually patrols, _NPCScan would ignore it. When one of these tamable mob false-alarms happens, you'll see a message in your chat window explaining why it got ignored.

Since this makes tamable mobs are so difficult to track, I suggest you fly to the tamable mob's zone first, clear your cache, and then search for it.; Any time you pass through a populated area like Dalaran, you risk filling your cache with popular rare pets.

For Battle Pets there is no way for it to determine if a mob is a spawn or someone's pet. Many Battle Pet addons and just opening the Pet Journal will often cause Battle Pets to become cached.

    Seeing as how it's not broken, and you can add any new monster you like to it yourself, an update would only change the version number and not a lot else.

    Hypersensitive political-correctness is morally unserious.

  • #2166

    Whenever there is a new client version, the addon managers need to update the number in their addon(s) toc file. Until that number is updated, the wow client will consider the addon out of date, wether or not it actually works.

    If NPCScan works without LUA errors when changing the Interface version to 50200 in the .toc file, then it is a technical detail on your part to add new names/IDs.

    Just like waypoints for the TomTom map extension addon, plenty of people post the commands to add npcs to NPCScan on reference pages both here and on wowhead.

    so you are saying your npcscan works? when i type /npcscan, it shows "Type '/help' for a listing of a few command". apparently the addon is outta date.

    Sounds like your addon isn't loaded.  Did you check the "Load Out of Date Addons" box?

  • #2144

    Is there a way to permanently delete some NPCs from the scan?  I have to say, Sha of Anger and Alani... not so rare.  It's actually quite annoying to hear the NPC scanner go off every time I clear my cache, only to find that it's those two again.


  • #2146

    /npcscan, click on the name in the list, click the little - button in the very bottom right.

  • #2143

    If the addon is not working for you, i had the same problem. It never went off when I came across a rare. I tried every option in the book, cleared cache and reinstalled the addon multiple times. What I finally did was go to "other downloads" here, and downloaded the npcscan version prior to the latest update. Now the addon is actually working, and haven't seen any problems with it so far :)

  • #2142

    Could you add an option to share all npc's across all character's, so that you don't have to add each npc you add to every alts list.

  • #2147

    Agreed :l I don't understand why any addon defaults to separate settings per character, much less those without even the option to have a global setup. I shouldn't have to copy wow\wtf\account\accountname\servername\charactername\savedvariables\npcscan.lua from character to character outside of wow like I do every time I make changes :P

  • #2141

    This Addon really needs to be updated it causes a lot of lua errors and I really like having it.

  • #2140

    Where is the Creature Cache in MacOSX? There is no base Cache folder in the WoW folder, but there is under WoW/Data. But they're all named patch-base.....

  • #2139
