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.

    Is there a reason why NPCScan doesnt alert you when you find Gondria or Skoll in Northrend?

  • #1735


    Starting to camp for TLPD, I have run into the following problem:

    I camp while doing other things (of course), but those things mainly involve use of the computer.
    I have enabled sounds in background and can clearly hear the music from The Storm Peaks while doing other things.

    I was watching a youtube video in full screen (maybe this is the cause), and after watching, I tabbed back into the game to comfort my mind. As soon as I got tabbed in, NPCscan went off.
    It had found vyragosa, but not at the moment of tabbing in It was a good 10 minutes ago.

    I did not get a sound while alt-tabbed. I can understand this being because of youtube on fullscreen, but I'm worried that any moment that you're alt-tabbed will delay the caching in WoW, and therefore the alerts.

    Could you please clarify?

  • #1736

    Hi Pathemeous I had the same problem as you did at one point too. The way I fixed it was to use Full screen in windowed mode. Normal Full screen seemed to cause the delay your talking about. Hope my info helps you.

  • #1746

    Putridus the Ancient was scanned when camping TLPD (no idea how, but the guy is big so I guess its caching range is big as well?) This was while I had WoW minimized in Windows (Fullscreen) mode. 


    therefore, above is confirmed.

  • #1732

    Dose this not work for mysterious camel figurines anymore!?!


  • #1730

    Annoying, but my NPC scan found the corpse of the Time Lost Proto Drake and now it's counting it as though I already killed it.

  • #1733

    @ haiminh, NPC scan will trigger when ever the npc is found ( dead or alive.) there is cache issues but its not that bad considering the addon is not counting it as kills.

    @ nija, you can still find the mysterious camel figurines, it just takes a lot of time to find it and have npc scan trigger. It took me almost 12 hours of flying around till it triggered and I found it.

  • #1726

    obviously not updating as needed, I assume project  is abandoned\


  • #1725

    need to rewrite this to include and update cache script functions. Your original idea is sound, but it doesn't include refresh to current cache.  The script should clear, and have a time delay script, and close and refresh.


  • #1724

    Got quite annoyed when I decided to pickup a herb after being idle for TLPD for couple hours to find him dead right next to me. Apparantly the function to search for "already catched" doesn't work. I did a cache clear and tested, it found him now. But must say this got me quite annoyed. :P

    Is it possible to have a time and date stamp when a creature is found?  


    For instance, searching for TLPD or Aeonnaxand go away or go to sleep with the speakers on and then wake up later or return and see the scanner found the mob but it's already taken and gone.  With a time stamp we can set up a rough estimate when the mob potentially will respawn.

    Doesn't have to be permanent considering we clear the creature cache for the next time.

  • #1727

    For this, any chat addon with timestamps enabled works great.

  • #1720

    I added a long list of Kalimdor and Eastern Kingdoms rares last night and went through the zones a couple of times finding about 30-35 of the rares in the 50-60 range (epicness!), however, logging on today, the list of rares to track is back to the custom set one with only tbc, wrath and cata rares?

    Why doesn't it save the list from logoff to logon?
