Old Crystalbark

Old Crystalbark is a hostile level 71-72 rare tree giant with approximately 14 -14.5k health. He can be found in Coldarra wandering around the Nexus in the Borean Tundra and is one of three rares in the zone. The other two are Fumblub Gearwind and Icehorn.


I have indicated his patrol location in blue on the map below. This npc is part of the Northern Exposure and Frostbitten achievements. He drops Crystalbark's Toenail which are level 70 bind on equip plate gloves 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.

Deathmaw

Deathmaw and Worg Pup

Deathmaw is a level 51 aggressive rare wolf that can be found in a few different locations north and south of Dreadmaul Rock in the Burning Steppes. (I have indicated where he can be found in red on the map below.)  He drops the typical green item and a decent amount of experience for toons around his level.

He is also desirable as a hunter pet as he has a unique dark brown coloration and he barks when you click on him. He also matches one of the random Worg Pup colors and the two look really cute out together. The Worg Pup used to be a reward from the quest Kibler's Exotic Pets where you had to go into Lower Blackrock Spire and catch a pup. The pup now drops off of Quartermaster Zigris in Lower Blackrock Spire. 

Zaricotl

Zaricotl is a level 48 aggressive rare carrion bird that can be found south east of Dustwind Dig in Badlands. (I have indicated where he can be found in yellow on the map below.)  He drops the typical green item and a decent amount of experience for toons around his level.

He is also especially desirable as a hunter pet as he has a totally unique model. He is the only tamable white vulture in the game.

Xariona

Xariona is a level ?? rare outdoor boss with approximately 12.9 million health. She can be found in Deepholm flying extremely high in circles above the Temple of the Earth. She flies very quickly and can fly in both clockwise or counter clockwise directions. She is also notorious for getting Aeonaxx campers excited when NPCScan goes off.

As of patch 4.1 Xariona drops one guaranteed purple item. She drops Xariona's Spectral Gauntlets which are item level 359 mail physical dps gloves . She also generally drops about 20 gold, another epic item and some nice jewelcrafting designs. 

She 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

Oozeworm

Oozeworm is a level 38 rare worm that can be found just west of the Stonemaul Ruins in Dustwallow Marsh. (I have indicated where he patrols in red on the map below.)  He is especially desirable as a hunter pet as his yellow color really makes him stand out. The only other tamable yellow worm in the game is another rare spawn called Grubthor, who is level 56 and can be found in Silithus.


Oozeworm is an exotic pet, he can only be tamed by hunters who are at least level 69 that have the top-tier talent from the Beast Mastery tree Beast Mastery which allows the taming of exotic pets.

Spiteflayer

Spiteflayer is a level 55 aggressive rare carrion bird that can be found just south of Nethergarde Keep in the Blasted lands. (I have indicated where he can be found in yellow on the map below.)  He generally drops either an Imperfect Draenethyst Fragment or a Flawless Draenethyst Sphere, each of these items begins a quest. When turned in you will receive a "junk" bag for the imperfect one and a chest for the flawless. The junk bag usually contains a green item and the chest will have a blue.


He is also especially desirable as a hunter pet as he has a totally unique model. He is the only tamable two-headed yellow carrion bird in the game.
