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 & 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.
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.

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.



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.  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.  That page's URL will look like

32500 is Dirkee's NPC ID.

    It does get cut off. I added some print()s showing private.macrotext was 1030 characters, with the cut-off being at 1023, the T in CheckMacroTarget(). Printing the macro text showed that the Ghostly Pandaren Fisherman and Craftsman (manually added, continent: Pandaria, no zone restriction) are getting added into the Timeless Isle mob list. Removing my manual additions "fixed" the problem, but you'll probably want to find a better solution.

  • #2989

    According to curse im using version with english as the language

  • #2988

    Which version of NPCScan are you using?  The release version or one of the alphas?  Also are you playing on with English as the language or with a diffrent language selected?

    I was camping Moldo One-Eye yesterday, today I moved to the Timeless Isle to camp the Champions of the Black Flame but the error goes off regardless of them/any other rare/no rare being nearby.

    Vignette alerts are working great though!

  • #2983

    What a "toast" or "toast window" is, is not intuitive. For anyone else wondering, it's the popup frame in the bottom right of the screen that's displayed when you encounter a rare mob. Maybe you see it differently, but I don't see "toast" as part of the end-user addon vernacular. As far as I know, this is something new to NPCScan that its developers have included since the prepatch.

    1. I'd like to see the option tooltip in _NPCScan's Interface settings be a bit more helpful. Currently, it reads "Show alerts in a Toast window, instead of in the chat log." Maybe something like "Show alerts in a popup Toast window at the bottom right of the screen..." (they don't seem to be movable).
    2. Further, the "Test Found Alert" button does not show the Toast window, causing me to question the effect of the "Show As Toast." and "Keep Toast Persistent." options. It's inconsistent to show just a part of the alert "experience" when I press the test button. The button should show everything....READ UPDATE

    UPDATE: As I dug around in the source code for this addon while writing this comment, I believe I found a bug. When I click "Test Found Alert", you are attempting to show the toast, but you're checking the wrong options variable, causing the toast window to never show. To fix this make the following change:

    I think once you fix this, figuring out what the toast window is becomes much more clear!

    A question: would it be possible to add the macro to an attack? So that every time you use for example your main attack (frostbolt as frost mage) you also scan for rares. And if it find one, it automatically set the target back to the original target that you don't loose your target even if you found a rare.

    Sorry to ask, i don't know anything about modding; but if it would be possible to use it together with your main attack, it would be easier to find something instead of pressing a button again and again.

  • #2978

    So basically having NPCScan is just as good as NOT having NPCScan for a hunter..

    Thanks while it lasted.  It was a great addon.

  • #2976

    If NPCscan doesn't find a way to track old world rares, I'm going to have to switch to Silver Dragon.

    They make no claim that the cach on old mobs is no longer working.

  • #2981

    Look here:

    Blizzard killed it. We're not just saying this.


  • #2977

    NPCScan & Silver Dragon work on the same principal and the cache change broke for both.  I've been up front about it letting users know.  While Silver Dragon still has cache searching listed on its page, check its Change list for the 3.1 build  " - Removal of cache scanning"

  • #2975

    I'm not saying any of this against the designer of this addon, but it seems to me that Blizzard has renendered NPCscan useless for all old content.

    No more being alerted if Time Lost is nearby, or Vyragosa, or Skoll, or Aeonaxx, or any of the other rares, some of which drop mounts, others are saught by Hunters, and MANY of them are saught by achievement collectors.

    Imagine how much fun it'll be to find Poseidus now. It will require swimming down to each spawn-point, then back up to the surface to continue to the next loction.

    You can literally walk right past a rare now, and if you don't know it's rare, you'll just pass by. This kind of defeats the entire purpose of the addon.

    When you're camping a rare mob spawn point, it [was] nice to be alerted when it spawned. If you walked away from your keyboard for a moment to go bio or get a drink, when you came back, knowing that the mob had spawned and was killed let you know that you could take off and come back another time. Not knowing it spawned, you will now waste hours... OR DAYS is some cases!

    I just got the rare Hydra Hunter's pet that spawns outside of wailing caverns in the cave. I had no way of knowing if it had spawned and been tamed while I was AFK. And when I targeted it to tame it, NPCscanner did not go off.

    So again, this addon is absolutely useless for all old content. Too bad, it was a very good addon in it's day.

    I don't know a lot about these things, but isn't there some other way of having the addon track old rares?

  • #2979

    Currently there are really 3 ways to track a mob: Vignette, Macro, Nameplate.  Currently NPCScan does the first 2 types of scanning, and I am trying to get a version of Nameplate scanning working.  Unfortunately this type of scan requires you to 1) have nameplates on, 2) get close enough to a mob so its nameplate shows up, 3) can easily be interfered by addons that modify nameplates, which is why NPCScan mainly relied on the old Cache scan.  While SilverDragon does have Nameplate scanning, it appears to not currently be working in WoD as I loaded it up & landed on Humar the Pridelord and did not have SilverDragon give an alert untill I triggered a mouseover alert.

  • #2973

    For some reason the setting for "Show alert for Vignette mobs" seems to be character specific, while all the other settings are shared between all chars. Any specific reason for that?

  • #2968

    Is this intended?

    In "testing" the new NPCScan, I went ahead and ran around Cataclysm looking for a rare. I ended up finding one in Vash'jr.

    The documentation on the changes led me to believe that, as long as I was spamming my Dynamic Button macro, I would be alerted the second I found the mob just like the old days (because the macro would target the mob and then the alert would trigger).

    This was not the case.

    >I targeted the mob and saw it on my minimap. No alert.
    >I mouseover'ed my target on my UI. No alert.
    >I clicked my target on my UI. No alert.
    >I mouseovered the monster's physical 'body' in-game, an alert was played.

    Is this the limitation now? That means this addon is completely out of the question for semi-AFK-farming rares unless you can be 100% certain your cursor will be over their physical body. There was, at least, a workaround if you were present to spam the Dynamic Macro but not present enough to actually look at your minimap (eg, watching a movie).

    Is it possible to make it so the alert goes off when you target a rare via the dynamic targetting macro?

  • #2969

    If it was found via the dynamic macro it should have triggered an alert, if you targeted via some other method, then the alert would not play.  Which mob was it so I can dig deeper. As for the other scenerios, the only time the mouseover alert will trigger is if you mouse over the physical mob.
