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.
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...
