NPCScan

NPC scan is an absolute necessity if you plan on finding Aeonaxx. You can download it from Curse.com. I also highly recommend downloading NPCScan.Overlay as well. (NPCScan.Overlay adds an overlay to your map which displays where rare mobs patrol.) What NPCScan does is track rarely seen mobs in the game by proximity. When a rare npc is found npcscan checks your creature cache and the mob becomes "cached". It is extremely important that you clear your cache often. Npcscan will NOT be able to find a cached npc again until your cache has been cleared. Although kind of annoying, clearing your cache is relatively simple.

To clear your cache:

1. Exit World of Warcraft.
2. Delete the “Cache” sub-directory inside your World of Warcraft folder.  For example on a standard Windows XP installation, you would delete the folder “C:\Program Files\World of Warcraft\Cache”.
• Advanced users can delete “C:\Program Files\World of Warcraft\Cache\WDB\enUS\creaturecache.wdb” specifically to improve log-in times, where enUS is your language code.

When npcscan finds a rare spawn it will alert you with a loud sound. (I prefer to keep mine on the default setting.) Your screen will also pulse red and an animated button will appear displaying the name of the rare spawn and a small picture of it. When you click on the animated button npcscan will attempt targeting the rare spawn. I made a short fraps video testing the found alert below.

When you download npcscan it will have one npc ID for Aeonaxx, which is 50062. The ID 50062 is the one for Aeonaxx when he is still friendly before being mounted. Once mounted Aeonaxx's ID will change to 51236. Make sure you add this ID under the Custom NPCs tab. Put in the number 51236, world is optional (I put "Deepholm" in mine) and in the name field you can put in Aeonaxx. Be sure to hit the little + sign to add it to the list.

Another ID you are probably going to want to add is 3868. This ID is for Blood Seeker. Blood Seeker is a non-elite level 15 bat that torments us by sharing a spawn point with Aeonaxx. Blood Seeker spawns exactly where Aeonaxx spawns. If your npcscan goes off, and it's Blood Seeker that you've found you can be sure that Aeonaxx won't be spawning again for several hours. Here is a screenshot below of the pesky Blood Seeker in the Quartzite Basin Aeonaxx spawn location.

VIEW DISTANCE:

Make sure you have your view distance set to "ULTRA" when you are camping for Aeonaxx. If your video card can draw Aeonaxx your NPCScan will go off. If your settings are too low you may not see him if he spawns.

When you're ready to begin the hunt for Aeonaxx your Npcscan should look just like the one in the screenshot below. Note how all three NPC IDs are included: 50062, 51236 and 3868. Also notice how there are no red x's under the cached column.

Remember, DON'T FORGET TO CLEAR YOUR CACHE!! If Aeonaxx spawns and has been cached npcscan will not go off.

One Other very important piece of information I'd like to add is IF YOU TAB OUT OF THE GAME YOU WILL NOT BE ABLE TO HEAR NPCSCAN IF IT GOES OFF. If you're planning on sitting your character on a spawn point and then tabbing out and browsing the web, this is not an option if you want to find Aeonaxx. This happened to me once when I was camping on my husbands toon. He had tabbed out of the game to research something on the web. When we got back into the game Npcscan's animated Aeonaxx button was right there in the middle of his screen, the alert was going off, his screen was flashing red and general chat was all about who downed Aeonaxx. We won't make that mistake again...
