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 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.

    this is a brilliant solution!

    good job :D

  • #1669

    Any chance of NPCScan including the Mysterious Camel Figuring (id 50409), perhaps with a route too? These may help:




    Whilst I know how to add it in manually, having the overlay work for it would be a great help (no 2nd monitor here :P ).

  • #1664

    Should have a ability to clear cache every time you log off... 


    >>Also to user 'WoWWarlock'

    -Only people in your party can see raid markers. If your not in a party, you are the ONLY one who can see those.

    I figured that out shortly after making that comment but I would still like to be able to turn off the raid markers because I like to snap a screen shot of the rare mob before I kill it and I would rather not have the raid marker in the screen shot. As it is now, I have to remove the marker before the screen shot.


    It's not a major issue but would it really be that much trouble to allow us to toggle the raid markers on and off?  It's not really needed anyway since the object is easy to spot once you have it targetted.


    Thanks for the reply.

    You are looking for another program executable, or a windows batch file, or a windows shortcut. Author most likely did not add a separate file in the addon package because people have this cache in so many different places which gets confusing.
  • #1663

    i installed this with curse client but im not sure how to use it, im trying to find time lost proto-drake. any help please?

  • #1666
    Do not have to use anything. Works by itself with the default settings when you log into the game. If you ever find the corpse and want to find it again later, remember to clear your cache.
  • #1659

    I am standing in Valiance Keep in Borean Tundra and NPC scan goes of detecting Putridus The Ancient? That rare is in Icecrown mlies away. Isnt that a bug?

  • #1665
    Not a bug in npcscan. It is a bug in blizzard when it releases the mob id to the game. Npcscan can not just ignore it if it is far away because of the way cache works.
  • #1660

    I had a similar experience. I was in stormwind and the alert for modus goes off. He is in Hyjal.

  • #1672

    It appears mobs like Mobus and Putridus are viewable/targetable from a much longer range; not unlike the Fel Reaver and Whale Shark. It might be the reason they're cached when you're that far from them!

  • #1658

    When I delet the file 

    C:\Program Files\World of Warcraft\Cache\WDB\enUS\creaturecache.wdb

    The NPCs I have looted still sho up in my list with an "X" by the name. The cache is not clearing or what? 

  • #1661

    Don't forget to clear your cache when WoW is closed.

    If you only log off, the cache comes back straight away.

    Hope it helps
