About _NPCScan

If you care at all about my wishes, you won't download this AddOn from SolidIce: They are leeching it from the site I actually choose to put it on.

_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 Keybind->Other_>NPCScan 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.

“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.

    Problem with Gondria

    I was flying around the spawn points of the spirit beast Gondria, and I got the NPC alert at aroung 62:42. I spammed the targeting button, but I didn't get any targets. I flew around her other spawn points 4 times each, while still spamming the button, but she wasn't there.

    Is this a bug? Has anyone experienced this? I tried logging out and resetting my cache, and when I got back and the cache was clear, I flew around her spawn points again, and I did not get any alert.

    There were no hunters or other people in the Zone at the time that could have tamed her / killed her.

    Sorry if f this has been asked already, but is there any way to add the option to automatically take a screenshot when _NPCScan goes off?  

    That would be helpful for when I end up AFKing too long or the game crashes, so when I log back in and I see the mob cached, I can check my screenshot directory to find out when exactly it spawned.

  • #1798

    I jsut cleared my cache -being doing it no problem for a while- and when I logged back in I had my Frostbitten and Bloody Rare reset on my main.  Yes the progress went to nothing from near completed.

    I logged on an alt and relogged to main and it copied over all the progress again. /phew.  To double check I deleted cache again and same thing happenned -lost progress, logged on an alt, reacquired it-

    Made a ticket, I will let you know fo their response.

    I added this addon to the addons folder but i can't choose it in the game why?

  • #1796

    Just recently got this addon.  However, it is seeing NPC's I've already came across. 

    I tried to delete my cache folder, but it is still seeing these and telling me to delete my cache.

    Wow did not create a new cache folder either.  How can I resolve this so I can find the NPC I am looking for???

  • #1794

    I don't know why but having this addon makes all icons and text disappear from my glyph screen, I can mouse over something and the tooltip will pop up but I can't see any icons so I can't see what glyphs I have on or what glyphs I know or don't know. Logged out and turned off this addon and when I logged back in I could see the glyph screen just fine. Any idea what's causing this?

  • #1793

    Hey there i found a bug sort of i've notcied that if your a hunter and have the rare as a pet that spawns in zone your in, the alarm would go off and target will be shown,  For instance i found the Spirit wolf in Twilight, logged of to clear the cache and brought him back out and the alarm sounded.

    Another instance was also in twilight was going to look for sambas and i flew over the arena and another character was in there fighting and was a hunter with the pet Sambas the alarm sounded and targeted his pet.


    Just FYI.

    Awesome addon! However, I can't find my Cache file ANYWHERE. I downloaded via curse's client and NPC scan has no files anywhere on my hard drive, yet runs in game. Any suggestions?

  • #1795

    on the WoW folder, locate the cache folder and delete it  C:\Program Files\World of Warcraft\Cache

  • #1791

    Any idea when and if this will be updated for MOP? I love this addon! thxSmile

  • #1789

    Okay the past couple of days when I log on my NPC Scan has gone off. With NPC no where near the zone I am in.. First it was Morbus twice and now it is Putridus the Ancient. There is something wrong with the scanner..  Other than it works great!

    That's because those NPCS can infact be targeted from great distances, the scanner works based on when the NPC is loaded into the game, those NPCs are loaded even when you are very far away because they're scaled up in size.

    After clearing my NPC cache, I'm getting a NPCScan error. NPCScan itself seems to be working fine, BUT NPC Scan Overlay (where I've also posted the bug) isn't working.
