Seal of the Earth: 81, 50

Just visit the 3 Pillars first, then use the Seal of the Earth. That's the easy part. Hard part is killin the 2 mobs!

After dying three times, I was able to solo Blacklash and Hematus as a 54 shaman. If you've got the right talent spec (and 4-5 greater mana potions or better) you can take them out.

Some tips:
- It's critical to have 5 ranks in Improved Lesser Healing Wave. 5 in Tidal Focus and Tidal Mastery will also help (think "cookie-cutter NS build"). You'll be healing yourself a lot, and if you can't get your heals off while being struck, you're done for.

- I did this with greater mana potions. 700-900 isn't a lot of mana, but two for each fight was enough for me. Having better mana potions will make your fights noticeably easier.

- Knowing what to expect from the two dragonkin can help a bit, so here's the scoop: Blacklash uses a fire spell that always hits for exactly 500, while Hematus uses one that hits for 70-80 the first time and inflicts a magic effect that increases damage from each subsequent fire spell by 70-80. These effects stack, so Hematus' fire attacks will become more deadly as the fight goes on. The below strategy (necessarily) prolongs the fight by conserving mana for healing, so keep a close eye on your health as your fight with Hematus goes on.

- Fire resistance totems might help you during this fight. Their effect should be more noticeable against Hematus because of the nature of his fire attack. I didn't use them because I wanted to save mana, but you might find that they pay for themselves in the form of damage prevented (and consequently, healing not needed).

- I used a one-hander and shield for the fight. You might be able to use a two-hander, but keep in mind that both dragonkin have powerful melee attacks (I was taking about 250-300 damage per hit if memory serves, and that was with 45% damage reduction).

The strategy:
Before you do anything, kill a few of the 44-45 dragonkin near the pillar so you have some room to work with. If you use LB or shocks to fight them, be sure to replenish your mana before using your runestones. When you use the runestones, back away from the pillar immediately, or Blacklash and Hematus will both spawn right on top of you. Run away at first if they start attacking you, then come back when you've shed aggro.

Cast Rockbiter on your weapon. You can't afford to rely on Windfury's randomness, and Flametongue Weapon won't help at all (Blacklash and Hematus are immune to fire). Run just within aggro range of one (don't pull with a spell--save your mana) and pull him back from the pillar a short ways. Don't worry, you won't pull both of them.

Now, drop a Strength of Earth totem (your only use of mana other than heals). If you want to use Fire Resistance totems, cast one now as well. Start swinging away with your weapon, and resist the temptation to use shocks to deal more damage. You don't have enough mana to kill them with spells, even combined with melee. Let your weapon deal all the damage. With Rockbiter and Strength of Earth, your damage-dealing will be solid and consistent. If you have ranks in Thundering Strikes, Flurry, and Parry, you'll do even better.

When your health is knocked down to about 750, start spam-healing with LHW until you're back up to about 90%, then go back to attacking with your melee weapon. Don't fill your health back up all the way, or you'll waste mana. It's important to wait until your health gets low to start healing, because you want to regain as much mana as possible while you're swinging away with your weapon.

Once you've used mana equal to the amount you can replenish with a potion (say you've used 900 and you have a greater mana potion), use one immediately, then go back to attacking. This way, you start that two-minute potion cooldown early and get the opportunity to use a second mana potion in the fight. More mana potions means more healing, since you'll be using almost all of it for LHW.

Your SoE totem will probably expire two times (maybe three if you're not enhancement-specced) during the fight. When it expires, immediately recast it and heal yourself back to 90%. If you're using FR totems, recast them only when you recast SoE. FR will always disappear before SoE (at 54, your best FR should last 1 min., and SoE 1.5) but you'll still have FR down for two-thirds of the fight with this strategy. The idea is to minimize the amount of time you're not regaining mana while giving your melee attacks that extra punch you'll need to win.

Follow the above, and you can pull it off. Each one will take 4-5 minutes, perhaps a bit less if you're enhancement-specced. (My Rockbiter wore off just as I killed each one, so I'm judging the length by that). Be sure to bring a few drinks with you, and 4-5 extra mana potions (just in case something goes wrong and you have to try again).

Hopefully this will help someone (especially those who can't get groups together out in the Badlands--I never have luck forming groups there).

You can obtain this quest at 40, but the dragons you have to defeat are level 50 elites. The area where you fight them is also filled with a good number of other 40+ elite dragons. Bring a group prepared for a fight similar to a boss at the end of an instance and you'll do fine.

Also don't wait too long to finish this one, as the rewards are great for a character in the early 40s, not so great for early 50s. Note that if you don't intend to use any of the rewards, you should grab the chestplate, as it sells for nearly 2.5 gold.
