This is a Stoneguard (aka 330 Ele) build, so you have to run 330 hp (two superior runes and no runes of Vigor) and probably 15 AL armor. It is somewhat helpful to have a -20 hp offhand to offset the hit point gain from killing the bosses also.

Spirit Bond is there to heal the burning, but don't feel you need to use it constantly. Try to stay above half health, however, because the Diamond Djinns will be able to inflict a Deep Wound at that point.

Try to kill the Diamond Djinns first, in as much as possible, then the Roaring Ethers (so they don't steal all your energy) and then the Sapphire Djinns. You won't be able to kill a Diamond Djinn unless there are at least two other Djinns still alive. For the Sapphire Djinns, you'll need at least one other Djinn. Sometimes you just have to leave the last few and move on.

You can tank essentially an unlimited number of Djinn as long as you cast a Spirit Bond once every ten seconds, so feel free to round up as many as possible. You should be able to clear the first room in about 4 minutes and everything up to Leilon in about 15 minutes.

Fortunately, you won't generally get more than one or two at a time unless you're around one of the bosses. The trick is to make sure that you've got some duration left on your Protective Spirit+Stoneflesh Aura before you aggro any Roaring Ethers and draw as large group as possible to offset the energy losses. It's possible to pull the entire first room, for example. I think I usually fight only five battles up to Leilon.

No doubt that works quickly and well. It's a simple matter of personal preference, I think. For myself, I find walking around at 50% speed under Obsidian Flesh laborious, and I'm not too keen on sharing my drops with Ogden either.
