Walkthrough

The Fishing Platform

Items needed: swamp paste
Items recommended: small fishing net for a medium Ardougne Diary task
Starting the quest.

Talk to Caroline on the coast north of the town of Witchaven, east of Ardougne. She will tell you her husband Kent took her son Kennith to the Fishing Platform a week ago, and she hasn't heard from them since; other families have not heard from the fishermen there either. She wants you to talk to Holgart, who has a boat that can take you to the platform to investigate.

Talk to Holgart, and he will tell you his ship is in need of repairs. He will ask for swamp paste (not swamp tar) to fix it up. Once you give him it, Holgart will appear in a cut scene fixing the boat. Talk to him again to go to the Fishing Platform.

Investigate

Talking to Bailey.

When you arrive, you will notice the odd behaviour of everyone as they all seem to be in a zombie-like trance. Avoid interacting with the sea slugs; they will deal 3 damage if picked up.

Note: If you brought a small fishing net, you can catch a fish here to complete a task for the medium Ardougne Diary.

Look around and find Bailey inside a small room in the south-west corner of the platform. Talk to him, he will tell you about the odd happenings and the hauling up of the sea slugs. Pick up the broken glass on the floor for later in the quest.

Helping Kennith

Skills needed: Firemaking 30 to use dry sticks to light the unlit torch
Using the glass to dry the sticks.
Using the crane to save Kennith.

Pick up some damp sticks close to the ladder in the north-east corner of the platform, then climb up the ladder. Upstairs, in a room on the west side, past the crane, you will find Kennith. He will tell you that his father tried to leave days ago, but the fishermen stopped him from doing so. He will ask you to find his father, Kent and help him.

Go back to Holgart and talk to him. He will take you to a deserted island, where you will find Kennith's father stranded. Talk to Kent and he will tell you his story. Then ask Holgart to take you back to the platform. Talk to Bailey to find out the slugs' weakness - they are afraid of heat. He will give you an unlit torch, which he cannot light himself as it is too damp. Use the broken glass on the damp sticks, which are found near the ladder to dry them, then rub them together to light the torch (Firemaking 30 ). If you do not light it now, you will be damaged by a fisherman when going upstairs.

Climb up the ladder again (on the north-east of the platform), go into the room, and talk to Kennith. From outside the room, kick the badly repaired wall to make an opening, then use your lit torch on any fisherman or sea slugs nearby and then talk to Kennith again. Rotate the crane to save him, shown in a cut scene. Talk to Holgart to return to shore. Finish the quest by talking to Caroline.

Congratulations, quest complete!
