About _NPCScan

_NPCScan helps you find rare mobs through the use of dynamic target macros, mouse over alerts and for Vignette mobs proximity. Once a mob is found by one of these methods an on screen alert is displayed, in addition to an audio alert.

_NPCScan & Warlords

Due to changes in how the game caches mobs in WoD, it is looking like _NPCScan will no longer be able to auto detect non-Vignette mobs. Due to this the only way to find pre-MoP rares via _NPCScan will be via mouse over, nameplate, or the new dynamic target macro keybind being added. The new keybind will trigger a /targetexact …” macro that updates with tracked mobs based on the zone you are currently in. Vignette mobs will still automatically trigger an alert when the mob gets in range, and should work more reliably due to updates to the Vignette API.

V6.x Changes
  • Cache Scanning Removed - Due to changes in the way WoW cache mobs, NPCScan can no longer auto alert when mobs are nearby like it use to.
  • Dynamic TargetExact Macro Keybind - NPCScan now has a keybind you can set that will try to /exacttarget tracked mobs. This macro will dynamically update based on the zone you are in and which mobs are being tracked.
  • Updated Vignette Alerts - Vignette Alerts are now more reliable and show the actual mob when detected the majority of time.

If you have a question check the FAQ, or a problem create a ticket

If you have a question/comment about _NPCScan.Overlay please post it in it's comment section.


Dynamic Target Keybind

NPCScan now includes a keybinding that will trigger a stored dynamic target macro. Each time it is pressed, the keybind will trigger a /targetexact <mob name> for every tracked mobs in the current zone you are in, in addition to any custom added mobs. This macro will be auto updated based on the zone you are currently in. To access this feature, just set a keybind under the Key Bindings->Addons->_NPCScan->Dynamic Target Macro section. Note: To search via the keybind, you will need to continuously push the bind. Pushing it once will only trigger it once, it does not auto scan like it did Pre WoD.


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.


If you have nameplates turned on, NPCScan now has the ability to trigger alerts off them. This method is not completely reliable as it has to rely on name comparison, so if mob name that NPCScan has does not match it will not trigger an alert. Also the range is limited as you need to get close enough to a mob to have the game display its name plate.

Addons that modify nameplates may interfere with this.

“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.&nbsp; 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 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.&nbsp; That page's URL will look like

32500 is Dirkee's NPC ID.

    I'm new with all this stuff here so i'm a little confused, I DL the addon and deleted the Creature cashe, what do I do after that? is that it, I didn't notice any changes when I logged in. I feel like I did somthing wrong.

  • #1761

    If people want stop clearing the cache, I know of a shortcut that I still use today and works great. 

    Go into your World of Warcraft folder where your Interface, WTF, and Cache file are located. Click Cache. Click WDB. Click enUS (or whatever file is located in the WDB. There is only one.). This will show you all the individual cache for the game. Delete creature cache. Then log back into the game, BUT make sure it is in an unpopulated area free of NPCs on your NPCscan. The log in creates a new creature cache.

    After this is done, log out, go back to the creature cache located in your WDB, right click the new creature cache file, click properties, and check the read only option, then click apply and then ok to close the file properties.

    This will remove the need to delete the cache every time you log out. When you log out of the game, the cache is automatically cleared of any NPC you may have found.

    This did not work for me. Is the premise flawed or is my attempt flawed? Tried it several times, any ideas? It sure would be nice not to have to clear cache every time I log on. 

  • #1758

    Npcscan detect even if the npc is alrdy dead but the corpe still there? tks

  • #1771


  • #1752

    This works fine all the time but just recently i was in Storm Peaks an NPCScan went crazy saying i found Putridus the Ancient who spawns in Icecrown an i was knowere near Icecrown :/

  • #1753

    Putridus' "presense" is huge.  It's not that your NPCScan was broken, but that Putridus is such a big mob he can be sensed very far away. 

  • #1751

    This worked for me, While camping my Time-Lost Proto Drake without fail on two different accounts.

    Instructions to get away from having to clear your cache.
    Here are the instructions on how get around this being needed.
    Go to the menu Located in the little computer at the bottom in your UI
    Then Go to the Interface menu
    Then you will see two Tabs one of them say Addons click that tab
    Then you will see an option that says: _NPC Scan Menu + Click the plus to dropped down
    the full menu.
    Then you will need to click on the option called Search. This will display a page to the right that says 
    Search for Compleated Acheives NPC's --Check the box next to it. 
    Now log out clear your cache as normal this one more time.
    Log back in to game and check your work to make sure that the check box stuck.
    Then fly to a place that you know you've seen a rare and see if it shows up on your Largest Map.
    If you see the name of that Rare you've already seen in the little box in one of the 4 corners then you know it will continue to allert you every time you see a rare no matter where.

    There is no WoW folder anymore, so how is the cache cleared???

    There is a WoW folder. It was probably moved by a patch or PC update. Type  C:\Program Files\World of Warcraft in your windows search bar. If you use a 64bit system you may have to type  C:\Program Files (x86)\World of Warcraft.

    Just wanted to say thanks. This worked like a charm for me, I just got the Medium Rare achievement without even thinking about it. Thank you!

  • #1748

    Hey, I've been having a problem with NPCScan where it identifies and alerts me to the rare mobs... when I actually mouse over them. I can be standing right next to the mob (as I have done without even noticing in some cases) and the alert will only sound when I move my mouse over the mob and cause it's tooltip to display.

    To begin with I thought that because I had all my rendering settings to full, I was actually rendering mobs before they were cached, but that's a rather redundant speculation now that I look back on it.

    Either way, anyone have any ideas? I haven't tried reinstalling as of yet, but it's on my to-do list.

  • #1747

    I am not sure what has changed with this addon. BUT, lately I have to unintall/install it everytime I login to WOW for it to work...??? I have the box checked to search for completed NPC's and it still doesn't notify me anymore when it finds rares. If I reinstall it everytime it works. Any suggestions?

    Need suggestions for locating NPC

    Hi there!

    Let's say I'm in flying around gathering materials, when the NPCScan alert goes off and the icon of the NPC pops up. 

    I can click on the icon, which targets the NPC. How do I find it from there? It's usually not in visual range.  It's not on my minimap or regular map. I don't know what to do other than fly in bigger and bigger circles, hoping I come across it before someone else does. I've been lucky once or twice, but usually someone gets there long before me. 

    So far, I haven't had a whole hell of a lot of luck. I'm hoping to change that. 

    What do you suggest?

    Maybe you found it just as the corpse was despawning.  Otherwise, going back and searching the area again while hitting the target button will eventually find it if it's still there.
