when you attempt to shackle this guy he will aggro and attack you, you need to fight him and take him down to 1/3 hp when he will become friendly and start the escort quest... he hits hard and has much armor this quest is in no way soloable.
the escort starts and you will walk with him to blackrock mountain, on the way he will stop twice and spawn two elites and two normal mobs. before entering the mountain he will spawn 3 elite dragons before going inside. once inside 5-6 non elites will&nbsp attack you, grark will not stop walking so you need&nbsp to kill fast or he will leave the quest range and you will fail. at the top of the ramp inside he will again spawn two elites and two non elites, after these the quest is done. completed with 60 rogue 60 hunter 60 shaman

Get Grark down to 25% health or so and he submits to you. Then start the next quest to escort him to Blackrock Mountain. He walks through tons of NPC camps, but you can just ignore them and walk around and he'll be fine. He calls 2 elites and 2 non elites, and if you stand far enough back they don't aggro and he stands still. Then you can pick them off one by one with sap/sheep/charm/etc. and he starts walking again. Then he gets to the bottom of the Blackrock Mountain ramp and calls 2 elites humanoids and 2 elite dragonkin. Again, stand far back and you can take your time. About 200 feet up the ramp he summons 3 56-57 dragons, but they seem to have low HP or something because they went down pretty fast. Then when you get into the mountain, he laughs and a few seconds later about 10 or so non-elites run at you from around the corner. If you have a rogue/druid, you can have them stealth along with Grark and have the rest of the party wait. Grark will go up alittle bit farther, and call 3 humanoid elites and a 58 dragon. Wait for a bit and the 10 non elites will despawn and your party can catch up with you. Then sap/sheep/etc. and once you beat the last guys some green Horde NPCs come out and chop off his head. Good luck!

Only needed to use the shackles once to turn him hostile, at 20% he turned friendly again and offered a "?", followed by the escort quest.
No Orc in- and outside the Stronghold will attack him, so if you are able to stealth - good for you.
At 3 points he will stop and some of his friends will popup:
1.) 2x elite and 2x non-elite Orcs.
2.) 2x elite Dragonkins and 2x elite Orcs
3.) 3x elite Dragons

I've never done this quest before today and at lvl 70 ovbiously it is very easy, so I cannot judge how hard this one is around lvl 60.

There are a few tricks to make this quest easier for you and your group. First, clear the trash mobs out of the yard in front of Grark's stronghold FIRST, then get in there and defeat him fast. They will not have respawned by the time you bring him out.

When you are walking with him towards the mountain, do not walk directly on top of him, stay somewhat to his left. By doing this, you will be able to avoid the unrelated camps of mobs he will walk through. This isn't an ordinary escort quest he WON'T aggro non-quest mobs if your party doesn't come in their range. He's one of the bad guys, he's friends with all these mobs! The only mobs you have to fight are the ones that he spawns himself.

The first few groups he spawns are easy if you have a full party, because he stands still for them. But when you get up on the ramp, for the last couple of groups he will continue walking. You must pay attention to this and continue moving with him even as you're fighting the mobs. Don't get distracted. If he gets too far ahead of you, the quest will fail.

If you're having a hard time and you play on a PvE server, try doing the quest during peak time when many people are hanging around the mountain. The mobs aren't particular about who they attack, and several times while we were doing the quest some of them got trained away by people trying to help, or just innocent bystanders. This will help you, not hurt you (though it will hurt the people who get jumped by the elites!).

Grark Lorkrub is not located inside BRD - he is inside the Blackrock Stronghold (40,34) in Burning Steppes (just to your left as you exit Blackrock Mountain).

Be warned that when you use the Thorium Shackles on him to turn him hostile he hits quite hard - harder than most 58elites in the game, he also takes a bit of work to get his health down. Once he is around 30% you use the Thorium Shackles again to begin an escort quest. This involves him walking from Blackrock Stronghold around up into Blackrock Mountain and through to the other side. Along the way he will stop three times and spawn a npcs.

The first time is four Blackrock orcs, the second is two orcs and two elite Black Dragonspawn and the final time is three Searing Drakes.

Once at the other side you will be told to go to Kargath to collect your reward. If your quest was bugged like mine and you lost your shackles you can still complete the escort then talk to the quest giver to get another Thorium Shackle before turning it in.

You'll find him in the Blackrock fortress in the Burning Steppes (not in the instance).

Confirmed that you only need to use the Shackles on him once.

Getting to him and subduing him was tedious, but not difficult, as a 63 Holy Paladin. But then things took a turn for the worst...

When I "started" the escort quest, he did *absolutely nothing* for about 5 minutes. The whole place respawned while I was standing there waiting for him. I thought the quest was bugged, but then he abruptly started walking outside while I was dealing with the respawns! I panicked and chased him out, aggroing about a dozen freshly respawned mobs, who proceeded to kill me. Quest failed! I then had to abandon the quest, and go back to Kargath to get a new set of shackles. No fun.

I'm going to level up and try again, this time tediously fighting my way out while he stands there with his thumb up his butt. I wish I was a frikkin' rogue...
