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.

    my addon out of date .. but curse client  up to date..

  • #2090

    Well everyone who uses this is wondering what's taking so long to up this addon. It would be great to hear from you guys as to the status and maybe a time table as to when we can expect an updated version. But with 5.2 around the corner that update would now be useless. I'm patiently waiting for this as my list of ncp's i'll be tracking is growing.

    got two things that can make this addon better. 1: give an option to track found rares (basically eliminate the cache) and 2: UPDATE THE DAMN THING SO WE CAN USE IT

  • #2088

    here is thought : Update

  • #2087

    I like this addon alot but i hate that to make it work proper, i have to clear cache all the time or i have to make it always show all.

    Wouldn't it be smart to make some small changes, that makes you able to set/remove the v in done and then use done to track/alert about the npc's on the world map ?

    This way if you don't want an alert for a npc, you just put the done marker and its removed and if you haven't killed it yet for the archives, it will keep comming untill you have done it.

    And for custom npc's a little done button could be setin on the marker, so you could click that, to mark it done ?

    to clear cache.

    it is working fine for me.  I made a .bat file that replaces my WoW icon that automatically does it.

    @ Echo off
    del "F:\World of Warcraft\Cache\WDB\enUS\creaturecache.wdb"

    "F:\World of Warcraft\World of Warcraft Launcher.exe"

    the first part clears the cache, the second part launches wow.  you will have to change the extensions to be where your world of warcraft account is located.  So maybe c:\program files\world of warcraft...   something like that

    also if you want it to "look" like the WoW icon then just make the bat file somewhere else, and then make a shortcut to it on your desktop.  then change icon, and use the "..." button to go to wehre your wow.exe file is, click on it, and use that icon.
