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.

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.

    I have toast disabled, but i constantly get a second Alert (so it plays the sound twice, 2 alerts in chat and the vignette mob found button gets replaced by the new one)


    _NPCSCAN found > Vignette Mob: NPCNAME and right when i mosueover/target i get the second alert which just says NPC found, not sure if it's simply glitching if that isn't supposed to happen but it happens constantly and that shouldn't :)


    Updated with picture.

    i am not getting alerted to custom added NPC mobs. I tried to add Lil Timmy ID 8666 and he spawned but did not alert me. I saw his text in chat and completely missed him while fishing nearby.

  • #2964

    NPCScan does not auto detect mobs, so unless you were activly searching for it, the alert would not go off.

    Hi guys,

    Wanted to pass along what might be a bug I encountered. I was camping TLPD the other day at Bor's Breath, standing right on the spawn with my mouse over the spawn. I went away from my computer for a bit and when I came back the other guy who had been camping had killed TLPD.

    I personally saw and targetted/moused over the corpse, but at no point when I did this did the found alert go off. I went to my settings and clicked the "Test found alert button", it worked fine. I also tried the new targetting macro, which successfully targetted TLPD, but did not give the found alert.

    Lastly, TLPD did not appear to cache. No "X" appeared beside the NPC's name in the cache list or on the overlay addon map key, and the name remains yellow in the search list.

    I logged out and cleared my cache several times to see if the alert would ping on log in, but it did not. I chatted with the guy who got TLPD and he said his alert did go off and TLPD did cache.

    Finally, I went to the Vale of Eternal Blossoms to see if the vignette mobs set off the alert, which they do, so that's working fine.

    My tech specs: I'm updated to the latest NPCscan/overlay. Not sure if it has any bearing, but I'm on Mac OSX 10.9.5. I did not verify whether the other guy was on Mac or PC, but PC is probablly more common.

    Hope this helps,

    Maybe TLPD spawned in a different realm. Was the guy from another realm?

  • #2965

    It sounds like everying is working as it should.  I can only guess that when it spawned, the mob did not pass on the cursor to trigger the alert.  Because the mouseover/target macro are active searches, it has logic in them to ignore dead mobs from triggering alerts.  This is why you were not able to get an alert from the corpse.  Due to the cache changes, NPCScan no longer checks for mobs in the cache.  Beause of this it will never show a mob as being in the cache, even if you have seen it and it will always stay yellow indicating that it is being activly searched for.  Clearing the game cache is no longer needed and does nothing anymore.

    As for the other player you talked to, I can't draw any conclusions.  He got the alert, but there are a multiple ways to trigger them.  As for being in the cache, as mentioned earlier, NPCScan no longer usese/marked cached mobs.  Not sure what he was talking about.  Even if he was using an older version of NPCScan, the game changed how it handeled mob GUID, so the old version would not work.

    Where and how can I set this new Search keybind?

  • #2958

    Go into the WoW's ingame Keybind menu, then click on other. Scroll down to NPC Scan and set your key from there

    Yes that's unfortunate cache scanning no longer works.

    Regarding the dynamic targeting macro, could this work like a toggle? Hit they key bind, it fires the macro every 5 secs until pressed again or something like that. Spawn camping will be a pain in the ass if it requires the user to sit and mash they macro =(

  • #2953

    Unfortunately targeting requires a player interaction to trigger, which is why you have to click on the alert button to target one fount.  There is no way for the addon to trigger it in game.

  • #2951

    Boo, Blizzard :(Thankyou for adding the ingame message about changes to the way caching and therefore this addon work (or doesn't :(), that was much appreciated.

  • #2950

    I am currently seeing 2 warning popups when rares are found, one is the mob model, and the other is a test box with a little demon eye and a note stating _npcscan Found "mob name."  Is this something npcscan is now doing, and if so how do I disable the text box?  If it's not, do you have any idea what is doing it?


  • #2954

    Its from the new toast alert that was added.  It can be turned off via the options.
