So, I got my attunement on how to fish Lurker solo 2 days ago (10/14), and I want to share with you. :)
You fish Lurker Below in Serpentshrine Cavern. If you haven't cleared any trash there, you will be attacked by Frenzies once you swim in the water there.
What you will need:
- Elixir of Water Walking
- Noggenfogger Elixirs (bring a lot)
If you're a Mage, you can use Slow Fall instead of Noggenfogger, if you're a Priest, you can simply use Levitate.
Get to SSC (you'll need a raid group), you'll be here after taking 2 elevators.
Take the Water Walking Potion and start spamming Noggenfogger until you get the Slow Fall effect, then drop to the water. Why? Because, when you take a Water Walking potion, water will be treated as floor. And you'll drop from somewhere high enough to take fall damage, and remove the water potion effect. If you get to swim in the water, you're dead.
Once you land in the water, start walking to Lurker's platform.
Lurker's Platform looks like a debris with a giant shining pool on the center, you can see an overview here:
Beware to not fall in the water, Water Walking Potions bug a lot for me.
Here's the screenshot of me getting the achievement.
And that's it! Unlike fishing Gahzranka, you don't get saved to SSC if you fish Lurker. But be sure to fish it naked, or else you'll take some unwanted durability hits ^_^
Sorry for the bad english. Hope this is useful to you.
