Captain Foulwind

Captain Foulwind is a level 81 non-elite rare spawn located on a ship floating in the water above the Shimmering Expanse just south of Nespirah. He is only hostile toward Alliance players. Horde's version of this NPC is Captain Florence who spawns in the Alliance ship east of Captain Foulwind. He is not a flagged npc, so killing him will not flag you on a non-pvp server. Captain Foulwind doesn't drop anything of value, not even a decent amount of gold. He generally drops around 2g, and sometimes embersilk cloth or grey items. He does offer a very decent amount of experience though for players leveling in the area; approximately 42k xp non-rested at level 82. If your level 85 and you come across this guy, don't bother killing him, you really have nothing to gain.

Terror Spinner

Terror Spinner is a level 76 rare elite spider with approximately 16.5k health. He can be found on the eastern side of Zul'Drak in several different locations which are indicated in red below. He is one of four rare spawns that can be found in Zul'drak. The other three are Griegen, Gondria and Zul'drak Sentinel.

This npc is part of the Northern Exposure and Frostbitten achievements. He drops Calcified Web Spaulders which is a level 74 bind on equip mail shoulder item with a random enchant. Like other Northrend rares, he also drops Abandoned Adventurer's Satchel, which generally contains about 20 gold, a full stack of frostweave cloth, and often times a few crystallized elements.

Terror Spinner is also a tamable hunter pet. Please note that because it is also a hunter pet that even though you may not have seen Terror Spinner before, it doesn't mean that it isn't already cached by NPCScan. If a hunter has this tamed pet out near you, your NPCScan will cache it. If it is cached in NPCScan and this rare is up your alert will not go off. Be sure to check and clear your cache often!

Burgy Blackheart

Burgy Blackheart

Burgy Blackheart is a lvl 81 non-elite rare spawn with approximately 55k health. He is located at 57,70 in the Shimmering Expanse just south of Nespirah. The location is shown below in green. Burgy drops an incredibly fun vanity item called Burgy Blackheart's Handsome Hat which can be equipped in place of your normal helmet to make your character look like the one depicted in the screen shot below. The hat will make your character and all of your mounts slightly transparent and larger.

Shok'sharak

Shok'sharak is a non-elite level 82 Faceless one rare spawn with approximately 67k health who spawns in the Abyssal Depths in Vash'jir. He can be found in a few locations in the Scalding Chasm which is south of Promontory Point. The locations are shown below in green. As you can see on the map, I found him at the western most spawn location.

Shok'sharak drops Sussurating Treads of Shok'sharak, a nice bind on equip item level 346 plate caster boots. On my server they sell for approximately 400-500 gold. He also drops around 20 gold and for leveling characters killing him yields a hefty amount of experience (around 50k xp non-rested at level 82).

Jadefang

Jadefang Untamed, Tamed, & Non-Combat Companion pet

Jadefang is a non-elite, non-aggressive tamable rare found in Deepholm who if killed drops the Tiny Sale Spider companion pet. Here is a screenshot below of the Tiny Shale Spider pet. Please note that Jadefang can also be tamed by hunters.

The spawn timer on Jadefang seems to be between approximately 6-12 hours.

NPCScan

I posted a very similar post in my other blog Find Aeonaxx devoted to finding the rare spawn Aeonaxx in Deepholm. I cannot stress enough that NPC scan is an absolute necessity if you plan on hunting rare spawns. I have tried other addons with the same purpose, but I always come back to NPCScan. 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.) In the screenshot below you can see an example of this. The colorful areas are where different rares can be found, and in the bottom left hand of your screen it will tell you the name of the rare spawn using a nice color code to tell you which mob patrols in each area. When a rare is found you will be able tell the approximate location that it has been found right on your map because a small, almost transparent circle will appear in the color associated with the particular npc. As you can see below I found Shok'sharak in the western spawn location in Promontory Point.

 

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.
