Troll Sabotage Quest/Spoiler

Required Equipment

 * Helmet of the Deep (wearing it)
 * Boots of haste (wearing them)

Method
Find Jerom north-east of Edron (here).

Ask him about "Mission" and he will tell you that troll ruined him.

Go to the other side of the mountain (here) and jump into the river, put on your helmet of the deep and swim under the mountain.

You should fall down a floor, swim to the water vortex and you are another floor down. Go out of the water and follow the way up as far as you can go. Walk immediately north from where the last set of stairs take you, and you should make the jump. Note that you MUST run the full distance in order to make this leap. When you talk with him you will get Jerom's family necklace

Now Go back to Jerom and ask him about quest.

You see an elvenhair rope. It weighs 6.00 oz.
