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.

    Unless there is a fix to what just happened...
  • #1154
    I was in deepholm 2 nights ago farming and I came across Jadefang. I had him in NPC with 49822 and it did not show on my NPC scanner. It seems that the new mobs that you enter in wont show on the scan, anyone know a way to fix this?
  • #1155
    Also, deleting your cache every time you find a camel statue is annoying, wish there was a way around this.
  • #1153
    I would really love to see this addon updated with the new 80-85 rare mobs.
  • #1150
    Shouldn't Jadefang be 49822?
  • #1152
    Yes, Jadefang have ID 49822
  • #1149

    Also, allow us to select Deepholm as a 'world'
  • #1148
    Here's a list of ID's of new tameable rares:

    [50058] = "Terrorpene"
    [47386] = "Ainamiss the Hive Queen"
    [38305] = "Gorishi Fledgling Colossus"
    [47387] = "Harakiss the Infestor"

    And the camel figurines:
    [50410] = "Mysterious Camel Figurine"
    [50409] = "Mysterious Camel Figurine"

    Also here are some old tameable rares which I had in my saved variable:
    [5842] = "takk the leaper"
    [6581] = "ravasaur matriarch"
    [1140] = "razormaw matriarch"
    [14232] = "dart"
    [6585] = "uhk'loc"

    Could you please add an option so that we can add the zone aswell when we add custom NPCs?

    Big thanx Saiket for this great addon which I've been using since Outland :)

    And I agree with h0bs0n, the adrenaline rush I got when NPCScan triggered for the first time after I had been searching for hours and hours for Nuramoc in Netherstorm back in the days is priceless :)
  • #1146
    Great addon, the adrenaline rush when npcscan triggers is priceless \o/

    Got a question; Is there a way to share my customed IDscan with all my characters, as of now they only seem to be tracking on the character i added them on?

  • #1147
    I ran across that info earlier in the thread. It involves copying info from subdirectories of WTF/Account//. Look for the _NPCScan.lua files for each individual toon.
  • #1145
    Thanks for the great add-on! I'm using it to find rares while leveling archaeology.

    May I suggest a couple enhancements?

    First, can you do something to pretend that cached mobs have not been seen? Or, if NPC Scanner doesn't get notification for WoW cached mobs, can you add an NPC scanner cache to ignore mobs I've already killed?

    Second, can you add parallel functionality for other achieves? I'm thinking about the /love squirrels achieves, but also for Pest Control. Change the "Rare Mob" message to "Lovable Mob", change the screen flash color, and have birds sing when found.
  • #1135
    I noticed that the one rare in Outland and Time-Lost Proto Drake are permanent custom NPCs. May I make a suggestion for another one with the new zones? The Mysterious Camel Figurine in Uldum. It's a lootable object, but it's classified as a targetable NPC. Looting it gives you about a 95% chance to get a 25g gray vendor item and a 5% chance to be teleported to the steam pools in Feralas, giving you 20 minutes to down this guy with 250k health. He drops Reins of the Grey Riding Camel when killed (which is not sold by the Ramkahen quartermaster). According to Wowhead, there are two IDs for this, 50409 and 50410. I have yet to confirm which ID is correct since I haven't found one yet, but I have both in my custom list. I assume one is in a phased version of Uldum with the other one in another version.
  • #1144
    Just found a camel statue, was tracking with ID 50410. It contained dust only though.
  • #1142
    I hadn't heard of these before, but I'll be sure to add them with the rest of the Cata rares in the next version. Until then, you get a head start. ;)
  • #1140
    I think 50409 is the "real" one and 50410 is the dud. I found a ton of 50410s on beta after I discovered what these did, and it wasn't until I found 50409 that I got teleported to Feralas.

    I mean it may have just been a coincidence, and I still haven't been able to confirm this on live since the Figurines are a lot more rare, but it makes sense.
