For those of you who haven't finished Vashj'ir, about 42 quests in, there is a quest that calls you to Damplight Chamber (56,13 of Shimmering Expanse). You see some strange vision, and upon return, waves of enemy Naga spawn. You get a quest to defend this area, called Backed Into a Corner. After 50 Naga die, a boss spawns and when he dies, the event ends, and you phase out.
Drop the quest and you instantly phase back in. (This is where the real fun starts.)
- There is an endless spawn of Naga - about 3-8 are always active.
- There are 6 shaman NPCs and 8 elementals that endlessly help you fight.
- Damage each mob enough so you could loot it, let the NPCs finish them off. (The NPCs are pretty strong so I doubt Blizzard or any Target-Ground AoEs would work well, but I may be wrong. As a priest, I just Tab/Mind Spiked each mob once and let the NPCs finish them off.)
- Loot like crazy!
- If the spawn rates are too slow, you can stand on the edge of the water and prematurely pull more (They normally spawn in the water, wait a while, and then run in.)
Each mob drops roughly 22 silver, Abyssal Clams (Blood Shrimp AH's for a decent amount), Embersilk Cloth, Various vendor trash including Green quality items.
Not bad monetary return for one GCD, eh? Multi-Shot/Pestilence/Divine Storm/Cleave would work wonders.
