Easiest Spot For "Going Down" Acheive EVER

[Rauk]

Even lowbies will survive it here!

In Darkshore there is that whirlpool, not too far inland from the new town. Jump off one of the high cliffs into it- you need to be sure that you're doing it from land, not swimming your way off a waterfall into it. Not only will you fall into THAT water, there is a cutscene as you are sucked into the whirlpool, and it drops you FURTHER down into another pool of deep water, which gives you the achieve with no damage at all.

Also, killing the named nasty you may find in there will give you a quest item and another achievement.

Totally found this out by accident, trying to get to some copper.
