How to farm Zelnehlun?

I've searched, but I have found nothing, anyone know how to?

That's too vague for anyone to be of any use.

-What's your profession?
-Normal or Hard Mode?

Even that will get you answers. Normal mode is simple, every profession can probably do it. Just group them under the bridge, go on top and cast spells.

-Necro
-Hard

You can use A/E or E/A to farm just Zelnehlun. Or i've found if you go 55 monk and use a cover enchant and run like crazy you can make it to Zelnehlun without dieing from those first mobs.

You're lucky: N/A is the best profession to farm that guy in HM.

There have been at least 2 or 3 threads about this in the past couple of weeks. I do believe you when you say you weren't able to find anything by using the forum search; forum search on this board is kind of "outsourced" and hardly ever yields anything usable.

The secret of success is not to use the search function, but to browse the first few pages.

Here's something you could have encountered while browsing:
