Thartuk the Exile

Thartuk the Exile is a rare level 81 with approximately 74.3k health. He can be found wandering the road in northern Mount Hyjal starting at Nordrassil and continuing all the way past the Circle of Cinders. Do not be fooled by NPCScan overlay with this guy, it currently doesn't show the exact patrol area. He actually spawns much closer to Nordrassil than the overlay implies. I re-did the overlay patrol area in green on the map below to give you a better idea of where to look for him.

Thartuk the Exile drops Thartuk's Inimitable Gauntlets, which are bind on equip item level 325 physical dps leather gloves. He also drops around 20 gold, and for leveling characters killing him yields a hefty amount of experience. 

Garr

Garr and his Posse

Straight out of Molten Core, I'd like to introduce...Garr! Yes, he's back. No, he doesn't drop his bindings. Garr is a level ?? rare rock elemental outdoor boss with approximately 12.9 million health. He can be found patrolling west of Sulfuron Spire in southern Mount Hyjal. I have indicated his patrol area in red on the map below.

As of patch 4.1 Garr drops one guaranteed purple item. He drops Garr's Reinforced Girdle of Memories which is a bind-on-equip item level 359 physical dps plate belt. He also drops about 450 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

Terrorpene

Terrorpene is an ultra cool looking level 81 rare turtle. He shares the same model at Nemesis the elite quest npc which you more than likely have encountered if you've done any questing through Mount Myjal. Terrorpene can be found moseying along in the molten lava east of the Sulfuron Spire. (I have highlighted his patrol area in green on the map below.)

Terrorpene was meant to be a hunter pet. All he drops is a Crystalline Tear of Loyalty. If you see him up please ask a hunter friend to come tame him or announce that he is up in general chat, but please don't kill him.

Magria

Magria is a rare spirit beast cat with approximately 232k health and is located in Mount Hyjal in The Regrowth. She is one of 10 new rares put in place as a challenge for hunters to tame in patch 4.2.  (Full list at bottom of page)


I have highlighted the area she patrols in purple on the map below. Magria shares a spawn timer with Ankha who is a very similar looking spirit beast. (Magria has a very pretty blue hue.) Their spawn timer is somewhere between 6 and 17 hours. The NPCScan id for her is 54319, you will need to add it to NPCScan in order for it to find her. You also need to have completed enough quests in Mount Hyjal to have unlocked the daily quests at The Sanctuary of Malorne to be able to see Ankha and Magria. The final quest before unlocking the dailies is Aessina's Miracle.

Blazewing

Blazewing is a non-elite hostile level 81 rare phoenix with approximately 93k health who spawns in The Scorched Plain in Mount Hyjal. He looks just like Al'ar the Phoenix God, and my all time favorite mount in game Ashes of Al'ar. The location he can be found at is shown in blue on the map below. 

Blazewing drops Blazewing's Furious Kilt, which are bind on equip item level 346 leather caster pants with two sockets. On my server they sell for approximately 1,000 gold. He also drops around 20 gold, and I imagine for leveling characters killing him yields a hefty amount of experience. 

Ban'thalos

Ban'thalos is a non-aggressive rare spawn with approximately 387k health (added in patch 4.2) and is located in Mount Hyjal. He can be found circling high above the Sanctuary of Malorne. I have highlighted the area he is found in purple on the map below. I believe that his spawn timer is somewhere between 6 and 17 hours.  You also need to have completed enough quests in Mount Hyjal to have unlocked the daily quests at The Sanctuary of Malorne to be able to see Ban'thalos. The final quest before unlocking the dailies is Aessina's Miracle.

 

This is strictly a TAMABLE HUNTER PET. If Ban'Thalos is killed all he drops is a Crystalline Tear of Loyalty. If your not planning on taming him, don't be a douche. Leave him alone. 

Ban'thalos is a spirit beast. He can only be tamed by hunters that have the top-tier talent from the Beast Mastery tree Beast Mastery which allows the taming of exotic pets.

The NPCScan id for Ban'thalos is 54320.

Ankha

Ankha is a rare spawn with approximately 232k health (added in patch 4.2) and is located in Mount Hyjal in The Regrowth. I have highlighted the area she patrols in purple on the map below. Ankha shares a spawn timer with Magria who is a very similar looking spirit beast. Their spawn timer is somewhere between 6 and 17 hours. The NPCScan id for her is 54318, you will need to add it to NPCScan in order for it to find her. You also need to have completed enough quests in Mount Hyjal to have unlocked the daily quests at The Sanctuary of Malorne to be able to see Ankha and Magria. The final quest before unlocking the dailies is Aessina's Miracle.
