Expect to spend a couple of hours doing this one, unless you bring a big and/or overpowered group with you. The mobs are level 46-50 elites, and you have to take down 80 of them total. Just work your way to the top of Jintha'alor and you will find all your mobs. You may have to backtrack in places to pick up respawns since you need so many kills.

The Soul Eaters and Blood Drinkers are on the last two levels. Soul Eaters have an ability very similar to Mana Burn, so watch out casters. Blood Drinkers tend to hit hard and often, so be ready with heals. My level 55 shaman, with about 3800 armor, was getting hit for about 150 a pop.

The Berserkers and Shadow Hunters are on the two levels preceding the Soul Eaters/Blood Drinkers. The Blood Drinkers are similar to Fury Warriors, while the Shadow Hunters will use ranged attacks unless you close to melee range. For some reason, the Hunters can also cast Shadow Word: Pain.

The quest is long but you can stack this with several other quests out of Revantusk Village. If you just make your way to the altar at the top, you'll likely end up getting about a quarter of the 80 kills you need. The trinket reward is great for all melee classes, but casters not so much. You do get over 2g for completion though, so unless you wipe a bunch you should come out ahead. Not to mention all that xp from killing 80 elite mobs.

For the record, I completed this with a 51 and 55 shaman. Easy to pull the mobs one at a time. Just watch for patrols.

Very nice trinket all way up to Outland trinkets.

As of 2.3 the mobs for this quest are no longer elite.

This quest now gives 7050 XP as of patch 2.3

Since 2.3 Jintha'alor has become an XP machine. I went at 51 and did this quest plus all these at the same time:

https://vanillawowdb.com/?quest=7861 https://vanillawowdb.com/?quest=7861
https://vanillawowdb.com/?quest=7849 https://vanillawowdb.com/?quest=7849
https://vanillawowdb.com/?quest=7845 https://vanillawowdb.com/?quest=7845
https://vanillawowdb.com/?quest=7850 https://vanillawowdb.com/?quest=7850

If you've done the chain, you can also complete https://vanillawowdb.com/?quest=4787 https://vanillawowdb.com/?quest=4787 while you are there, but the others can all be picked up at the same time as this one.

Gobs of XP and several nice quest rewards for what really only amounts to 1/2 hour or so of grinding on easy mobs. Hex is still pretty tough, but not nearly like she was before.

Edit: forgot the Ancient Egg quest.

I did this quest recently with my recovering twink feral druid. Very, very challenging at 44, obviously. However, I highly recommend it. This was like a solo raid, I died over and over and it really pushed me to use every ability and to play as smart as possible, and of course there is a terrific reward at the end of it. I hit 45 in the middle of the quest which made a lot of the mobs orange instead of red, so my hit % improved quite a bit.

This was one of my favorite things I've done in WoW, it really felt like a cool accomplishment to do it, and it was a lot of fun.

I was drunk with power after finishing it so I gave a couple of ""what the hell?"" shots at the Hex-Priest...I would not recommend that, she destroyed me.
