The tower is located at around 18, 68

As you work your way up the tower that will be a box on each level. After opening a box and taking the object out several mobs will spawn (3 for the first, 4 for the next, and 5 for the last).

I tried the repetitive dieing approach. It worked even better than above. I bubbled standing on a raised section just diagonally across from the tower with divine shield (10s) and ran into the tower. I didn't see the first crate and ended up running past it up to the 2nd floor. At that point all the mob chasing me had given up. I accidentally aggro'd the ogre that is very near the 2nd crate (I could've avoided that if I'd been thinking faster) but by healing I was able to dispatch him without too much difficulty. Then I opened the crate and immediately ran up to the top floor. I lost all the newly spawned mob by doing that so I could immediately open the 3rd crate. At that point I tried to lose them by dropping all the way down the tower. I'm not sure how many lost but I think I still had several one me at the bottom of the tower. I didn't really try very hard to stay alive but I doubt I would have managed it if I had. So as a ghost I ran back in, found the crate I'd missed (took a bit of looking). Respawned by it, opened it immediately and then immediately ran out of the tower and bubbled as I left. That let me escape all the way to the alliance section with only the final ogre right by that section still aggroing me. Since I had plenty of mana I healed myself and killed him off (without any help from those lazy alliance soldiers I might add - they ignored the hulking great ogre in the middle of their camp!).

So one death and only 2 ogre kills (ignoring the several I killed to get near the tower) to quickly get all the items as a lvl 44 palladin is a resounding success.

For anyone who wants them the coords for the boxes are:
Box #1 - 18.2, 68.1 - it is off the walk way on a platform next to the wall.

Box#2 - 18.0, 67.9 - this one is next to the wall also

Box#3 - 18.2, 69.2 - again next to the wall

The boxes are very small and do not look like chests at all. When I died I just went to the next box and rez-ed at it. As a druid, at level 42, it was easy enough for me to solo; when you pop to elf form return back to cat and stealth as quickly as you can.

just a little sidenote: as you go down the ramp by the trolls entering the part with the ogres, there is a little post on the right hand sid with a kind of straw X on it, if you jump onto the ledge right by there you can cruise all the way round to the tower without the hassle of killing all the ogres on the way to it...

saves looooads of time =)

Update after patch 2.3. After opening each box, it seems like it'll spawn 2 ogres only. The duo always seems to be a Mauler and a shaman. Shaman always drops a fire totem.

As a rogue, have auto loot on and just stealth right after you loot. I avoided all the spawns this way.

also new in patch 2.3: the mobs are no longer elite, but there has been added several mobs on the slope up to the tower - there's now 5 where there used to be 2, so making the quest a little tricky still, but it's all in all easier, just completed it as 38 shadow priest..

DO NOT activate the tower defenses, it will only make the quest more difficult.

If you ignore the tower defense pedestal you will only have to fight at most two ogres at the same time as you make your way up the tower and there will be no need to corpse run.

If you want to get to the tower without having to fight the ogres, then look for the high ledge on your left as you pass under the huge archway leading to the ogre infested area. If you jump up on it you can hug the keep wall until you reach the tower without catching any aggro. This ledge will meet with the back side of the tower and form a sharp crease which you can use to get back up on the ledge again and shake any aggro if you decide to make a run out of the tower.

(If you decide to activate the tower defenses, you will attract up to six ogres at once inside the tower even with the protective elementals spawned to help you. Brilliant work by the Blizzard quest design team.)

I did search for a rusted key on the many sites & a jailor named Borhuin in Alterac Mtns is suppose to drop a rusted iron key 40% of the time, whether this is the key I don't know. I went over to where he was & killed him at lease 5-7 times w/no drop key. Gave up.I spent the better part of an hour killing him and waiting for respawns before I realized why he drops the key half the time. That key is for a horde quest, to free the orc in the top back room of the inn. I suspect the jailer will never drop the key for anyone not on the quest (which means all alliance). And ""Attack on the Tower"" is alliance only. So, for now I'm going with ""the quest is currently broken"". Really wish I'd known this before wasting several hours on it.

*Edit: apparently there are a half dozen or so threads about it on the wow forums, all of them ending with a blue saying ""this is a known issue, thanks"" and locking the thread. So, yes, it is confirmed broken.

This quest is NOT bugged anymore in patch 3.0.3. I just checked it out and it was possible to open the chest and loot the Ember Agate without any problems.

Enjoy!

The tower in question is inside Stromgarde up the ramp, where you found the shaman for Trelane's Defenses. I would NOT suggest activating the crystals defenses as 6 ogres appear and will pwn you if you cant handle them. Regardless of if you USE the crystal or not you will still complete the quest if you gather all of the items which are on each tier. Two ogres will spawn a few seconds after each box has been looted. This was a simple quest which i soloed as a lvl 38 ret pally.

Note- There is also an opening in the wall of the keep near the rear, you can get to it from either side but going clockwise you have more ledge to work with if you dont want the extra xp and such.
