Mobus - The Crushing Tide

Mobus <The Crushing Tide> is a level ?? rare outdoor boss with approximately 12.9 million health. He can be found patrolling around the Abyssal Breach in Vashj'ir. I have indicated his patrol area in orange on the map below. He is very large and can be spotted easily from far away.

As of patch 4.1 Mobus drops one guaranteed purple item. He drops Mobus's Dripping Halberd which is an item level 359 physical dps polearm. He also generally drops about 200 gold, another epic item and some nice jewelcrafting designs.

He is one of 5 rare outdoor bosses added in Cataclysm. There is one in each Cataclysm zone. All of these bosses are:

Akma'hat <Dirge of the Eternal Sands> - Uldum

Garr - Mount Hyjal

Julak-Doom <The Eye of Zor> - Twilight Highlands

Mobus <The Crushing Tide> - Vashj'ir

Xariona - Deepholm

Julak-Doom - The Eye of Zor

Julak-Doom is a level ?? rare outdoor boss with approximately 12.9 million health. He can be found in the Twilight Highlands in the northern most part of the zone patrolling just north of Kirthhaven. He is very large and can be spotted easily from far away.

As of patch 4.1 Julak-Doom drops one guaranteed purple item. He drops Vitreous Beak of Julak-Doom which is an item level 359 caster dps dagger. He also generally drops about 200 gold, another epic item and some nice jewelcrafting designs.

He is one of 5 rare outdoor bosses added in Cataclysm. There is one in each Cataclysm zone. All of these bosses are:

Akma'hat <Dirge of the Eternal Sands> - Uldum

Garr - Mount Hyjal

Julak-Doom <The Eye of Zor> - Twilight Highlands

Mobus <The Crushing Tide> - Vashj'ir

Xariona - Deepholm

Sian-Rotam

Sian-Rotam is a level 53 rare white lion that can be found in northern Winterspring. He used to be a summoned mob for a horde-only quest where he would appear and help defend his mate, Shy-Rotam. In patch 2.3 the quest became available to alliance as well. Now Sian-Rotam is no-longer summoned and is simply a rare spawn that can occasionally be found sleeping behind his mate underneath Frostsaber Rock. He will not patrol away from this location once he spawns in.

Sian-Rotam has always been a desirable hunter pet, especially for alliance. The only other tamable white lion in the game is Echeyakee. Echeyakee is a level 15 spawned lion from a level 13 horde-only quest that starts at the Crossroads in Northern Barrens. If you play alliance, unless you get very lucky or have a friend playing horde who can help you, Sian-Rotam will probably be the easier of the two to obtain.

Hawkbane

Hawkbane Untamed

Hawkbane is a level 70 rare white striped cat that can be found high up in Skettis Plateau in south eastern Terokkar Forest. I have marked the area that he spawns at in orange on the map below. His new spawn location is behind one of the tall Skettis dwellings. He stands in the middle of three dead arakkoa (one is which he will be eating for lunch) who for some reason show up as hostile humanoids when using the track beasts feature on a hunter.

He is no longer elite and he has absolutely nothing of value on his loot table.

He does however make a nice hunter pet. The only other cat in game with the same color and model is King Bangalash in Northern Stranglethorn Vale.

Syreian the Bonecarver

Syreian the Bonecarver is a level 73 rare vrykul with approximately 15k health. She can be found in eastern Grizzly Hills patrolling a very large area south of Drakil'jin Ruins. I have indicated the area where she patrols in red on the map below. She is also one of four rare spawns int he zone. The others are Arcturis (spirit bear), Seething Hate and Grocklar.

Syreian is part of the Northern Exposure and Frostbitten achievements. She drops Syreian's Leggings which are level 72 bind on equip leather pants with a random enchant. Like other Northrend rares, she 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. She also yields a decent amount of experience for leveling characters.

Shanda the Spinner

Shanda the Spinner is a level 18 rare grey tarantula that can be found in southern Loch Modan southwest of Ironbrand's Excavation Site. She spawns in the cave that I have circled on the map below, she does not patrol once she spawns there. 

She drops the typical green item and a fairly decent amount of experience for leveling characters.

She would also make a nice hunter pet for low level alliance characters that stumble across her. She does not have a unique skin or coloration but she is probably the first in this color that dwarven hunters can find without looking too hard. Low level Horde characters looking for this same skin and color should check out Creepthess, another rare spider in Hillsbrad Foothills.

Shanda is one of 5 rare tamable hunter pets in this zone. All of them are:

Ashtail, level 16 bluish-grey fox

Gosh-Haldir, level 15 green crocolisk

Lord Condar, level 17 white condor

Nix, level 17 yellow firefly

Shanda the Spinner, level 18 grey tarantula
