About _NPCScan.Overlay

NPCScan.Overlay is an addition to _NPCScan that adds map overlays for rare mob patrols. When you search for a rare in _NPCScan, _NPCScan.Overlay will show where it patrols until you find it. It works similarly to keithgabryelski's Rare Spawn Overlay's , but supports the minimap and has a much smaller download size, along with a few new features.

Special thanks to Rare Spawn Overlay's patrol paths and Routes minimap drawing code for inspiration!

Note: _NPCScan.Overlay can integrate with _NPCScan if you have installed it, but make sure to keep both up to date if you do use both!

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


World Map

In addition to drawing paths on the World Map, _NPCScan.Overlay adds a key to a corner of the window with each rare's name. It only appears in zones that have rare maps, like Netherstorm as seen in the screenshot. Hovering over a mob's name in the key will cause the mob's path on the map to start flashing. If you need to read something under the key, it can be toggled by <Shift>-Clicking on the NPCScan.Overlay button on the map. The key can be repositioned by just moveing your mouse over top of it while holding the shift key and the key will jump to a different corner.

Most map mods like Atlas will inherit the key and overlays from this module. Even Carbonite's map display will show them.

Battlefield Minimap

The small “Battlefield Minimap” (AKA the “Zone Map”) also shows mob paths.


All shapes and sizes of minimaps are supported. Rotating minimaps work fine as well.

One feature not shown in the screenshot is a thinner 100 yard range ring around your character. It helps you gauge _NPCScan's detection range, so you can sweep through zones more effectively. This option can be found in the Minimap subsection of the options panel, detailed below.


_NPCScan.Overlay's options can be found under _NPCScan's main options menu, under _NPCScan > Overlay or as its own entry of _NPCScan.Overlay if _NPCScan isn't installed. This panel can be opened with the “/npcscanoverlay slash command, or “/overlay” for short.

The “Always show all paths” checkbox at the top of the pane overrides the instructions of NPC tracking mods like _NPCScan to hide unused paths, and always displays all known paths instead.

The rest of the configuration pane lists each map display's options. You can enable/disable each map from here, as well as configure individual settings for them.

Each map display can have its overall transparency set independently with the “Alpha” slider, so that it doesn't obscure the maps themselves.

    Have notice that from time to time the overlay colours seems to fade in and out

    This is the best way I can descibe it

  • #919

    When you mouse over the name of a mob in the key, it's path will pulse.

    Hi. - how can I change colours?

    Because: example Uldum, The Mysterious Camel thing - pink-coulered marks in sand-yellow ground is not really good to see ....


    And: cant we got changeable marks via checkboxes - one rare found he disappears from the map .... so I have to erase all the cache and so on ...

    <Edited 3/15/14>  The new version now lets you change the colors via the settings menu.

    I'll make it so the found rares won't be removed, in a future update to the addon.

    With this and its conterpart, is there a way for coordinates to be worked in, or is there a download that works with this that does have them?


  • #921

    Currently neither NPCScan or NPCScan.Overlay stores the coords of the Rares.  I don't know of any addon that does have them.

    Showing the Map Key

    I just want to inform everyone, that I THINK I found a solution to the missing map key for the NPC names. If you go to your map and shift click the little green compass in the top left corner next to the zone selection, it SHOULD show your map key. This option appears to be turned off at default upon installation. Shift clicking this little green compass fixed it for me. Hope this helps.

  • #914

    It works, thx very much

    Yes i have the Overlay button on Worldmap and i can clicking the colour way's only on and off.

    I Got the same problem, it dissappered after your last Update, does anyone got a fix for it plz??? A bit annoying not to be able to see which mob is which???

  • #911

    Which verison are you using? The release version or one of the alpha versions?  Are you using any other map addons (Mapster, Carbonite, ect) or are you using the default world map?  Have you tried toggling the legend back on using the Overlay Button on the map?

  • #908

    I have a question!

    In Uldum, we have respawn of Misterious Camel Figurine. Is it on this addon?

  • #907

    For some reason, using the Overlay makes it so none of my achievements show their progress anymore. For example, with it enabled my 100k valor achievement shows 0/100k, with it disabled it shows 93k/100k.

  • #901

    Has the Map "Legend" been taken out?
