Deadliest Catch

Deadliest Catch is a master quest that was released on June 7 2011, and first announced in the June Behind the Scenes. It requires level 70 Fishing, level 70 Thieving and level 67 Hunter. Players must face a sea monster named Thalassus, a name on which players voted at the end of May 2011 in a guaranteed content poll. This quest raised the minimum level for the Quest point cape for Hunter by 2 levels from 65 to 67 and Fishing by 8 levels from 62 to 70.

Starting up
Start the quest by talking to Jones near Fishing Guilds bank. He tells you that he needs a fearless fisher with him to catch a deadly sea monster, Thalassus. For the trip he needs an extra rower, a giant harpoon and a sea chart. You should exhaust all the options, among them he will give you a plan for a specific harpoon.

Obtaining the Sea Chart
To get a sea chart, go near the entrance of Fishing Guild reach the Master fisher. To get the map, pickpocket the Master Fisher. (This may take a few attempts).

Obtaining the Harpoon
To get a giant harpoon, talk first to Master Fisher. He tells you about Linza who will make you a giant harpoon. Linza is located at south of Hemenster, you can easily just walk north from Fishing Guild. Talk to Linza and she will make you a giant harpoon.

Obtaining a Rower
To get a rower, go to the tower of life located to the south-east of Ardougne. You can use Monastary teleport, Ardougne teleport and walk or just walk from the Fishing guild. Talk to 'The Guns' located out the front of the tower of life lifting a log above his head. He will say that he would be happy to help but can't due to his sea sickness. He mentions that Jones made him a potion so he could overcome his seasickness and says he could help if you made him one.

The potion contains Lowland heather and Builder's Tea. These ingredients can be obtained in the vicinity. You can get Builder's Tea from Bonafido outside the Tower of Life by talking to him. The Lowland Heather lies outside the tower. You must find the patch that is not infested with aphids. It should be the patch to the East of the Tower of Life. There are 3 patches lined up, pick the southernmost patch.

At the Sea
Revealing Thalassus' trails is like tracking in Hunter. Investigate certain ships in order to reveal Thalassus. The order is always the same, though if you fail 5 times, it starts over. You will have the option to loot up to three items from the wreckages. Once you find Thalassus, it knocks your boat over and you will find yourself on a deserted island with a bunch of mermaids.

Options to choose when talking to the mermaid looking people:
 * 1) The Thalassus has eaten Jones the mighty fisherman.
 * 2) It should, he's been hunting for decades.
 * 3) Very horrid! After he's killed the Thalassus, he'll probably come after you.
 * 4) Trust me, I'm a great adventurer, I should know.
 * 5) Did I mention Jones has a harpoon with him?
 * 6) It's no ordinary harpoon.

Any other option will result in them not believing you and requiring you to restart the conversation.

Return to the Sea
After you outwit the mermaids, they allow you to track down Thalassus again. Once again you and 'The Gun' must search through the wreckage to find Thalassus. Upon finding it, 'The Gun' will attempt to throw a harpoon at it. After the harpoon misses, Thalassus dives down. A few seconds later it pops to the surface again and spits out Jones the fisherman along with a tooth. The three of you make a run for it.

Finishing the Quest
Upon your return to the Fishing Guild, Jones the fisherman will tell you to deliver the tooth to Linza in Hemenster. A short cutscene will play and Linza will take the tooth from you can head off. Return to the Fishing Guild and talk to Jones the fisherman.

Trivia

 * The quest's name is a reference of the documentary/reality television series Deadliest Catch.
 * On the day of release, the rewards read: "Jones didn't have a strong enough line to reel in the rewards today. Pop back tomorrow when he's got himself a harpoon."
 * While one needs 70 Thieving to start the quest, the game guide claims 60. It was also stated in the Behind the Scenes - June that the quest will require a thieving level of 60. It also said the required Thieving level was 70 and the required fishing level was 67, when the quest was released it was the opposite way.
 * After this quest in order to obtain the Completionest cape, Thalassus must be caught ten times after the quest has finished.
 * This is the first interactable appearance of Linza, one of the seven Signature Heroes, after being mentioned in the first Fremennik Saga, Threes Company.
