The 2017 Hallowe'en event is a holiday event taking place from 19 October 2017 to 9 November 2017. The Grim Reaper seeks your help as he senses a disturbance in the force.
A player can start this event by talking to the Grim Reaper at the graveyard in Lumbridge, just south-east of Lumbridge Castle. The holiday event icon displays the location of the event on the minimap.
Speak to the Grim Reaper in the Lumbridge graveyard just south-east of Lumbridge Castle. He has been feeling a disturbance in the souls of the dead, specifically a soul who is struggling to break free. As he is unable to sense it, he will request that you look into this for him. Agree to do so, and he will tell you, vaguely, the locations of some spectral occurrences around Varrock: three within the city, and three south of the city walls. He will give you a death note, which lists the locations of the spectral occurrences, and offer you a one-time teleport to the city.
After observing each stranger, head to the Apothecary and ask him about the Halloween event. If you have the tin ore, wheat, and tomberries, he will mix them together and give you a murky potion.
Return to the Zamorakian altar in the south-east corner of Varrock. Use the murky potion on the altar to create a spectral potion. Use it on a masked stranger to trigger a cutscene. The stranger will then appear to come back to life, and proceeds to stab you (you will not lose any items).
You will end up back to Lumbridge where the Grim Reaper is. He tells you that he felt an incredible burst of energy from the spiritual realm, and rescued you from the brink of death. He then asks you what you had done, and angrily tells you that you have unleashed the "truest of all evil", the monster known as Jonas. He will then tell you to seek Jarvis, who had killed Jonas. To reach Camp Sapphire Lagoon, where he is found, players must board the small boat directly south. It is the same boat in which players use during the Misthalin Mystery quest.
Once on the island, enter the hut there. If players do not already have a bucket of water, there is a pile of buckets next to a well just east of the hut. Pick up a bucket and fill it by using it on the well.
In the hut, search the mouldy rug in the north-east corner. The trapdoor is locked, so you must search the hut for clues:
- Take the blue tattered book in front of the sofa. Read it. The riddle within indicates that a letter in the alphabet is missing within, which is C.
- Use the blue tattered book on the bookcase. A panel will then appear, revealing the letter L.
- Search the desk for a carved gem. Use it on the window with moonlight coming from it. Then use a bucket of water on the moonlit wall. The letter A will then appear.
- Clean the dirty walls inside the hut. There should be 4 of them. The numbers are 2, 3, 4, and 7.
- Search the drawers next to the bookcase to receive a note. This note indicates that the numbers around the wall should be interpreted as the letter$ P $, as$ 2 + 3 + 4 + 7 = 16 $, where P is the 16th letter of the alphabet.
The letter the player should decipher is CLAP. Perform the Clap emote next to the trapdoor to trigger another cutscene. You will now enter the basement where Jarvis is. Every time you finish the dialogue with him, use a bucket of water on him. There is a water barrel next to him to refill the bucket.
He will then say that he cannot kill him again, as doing so cannot guarantee their safety. He will suggest to trap Jonas somewhere where no one will ever find him. Choose the option Underwater. He will find an underwater cavern on the island, while you must find a way to trap him permanently. He will suggest that you speak to Traiborn. Make sure you complete the dialogue.
Do not teleport out, or the appropriate chat option will not appear. Instead, return to the boat and travel to the Wizards' Tower from there. Speak to Traiborn, who is found on the 1st floor[. Ask him how to permanently trap someone, and he will suggest a time bubble. He will give you a riddle: ]
PINS, HANDEGAB, and WOKBLISS. He will give you a set of notes to remember it.
Meet Jarvis at the dock on the island. He'll give you a diving apparatus and fishbowl helmet. You cannot enter the dive if you have a familiar or pet equipped, either out or in your inventory. You must bank or release your pet/familiar.Dive in via the anchor chain nearby. Jarvis has set up a bear trap to immobilize him for the time bubble, and will make himself bleed to lure out Jonas. Once he does so, go to the north-west corner, and Jonas will appear. However, some rocks will fall, forcing the player to lure him the long way back.
Players must taunt him by using the Beckon, Spin, Headbang, Blow Kiss, Raspberry, Yawn, or Salute emotes to lure him through the cave. Red corals are indicators of where he must throw his harpoon. While doing this, players must evade the harpoon he throws at the last moment to allow it to hit the red coral. Otherwise, they will be hit. If they are hit three times, the players must start over from the last checkpoint.
In addition, if a player takes too long to lure him, or if they speak to Jarvis, an arrow will appear in the map, indicating where to lure him. Once the player lures him next to Jarvis, he will be trapped, and Jarvis will instruct the player to use the time bubble on Jonas. If the player takes too long to do so, however, Jonas will fatally strike Jarvis, who dies. The player will then use the time bubble and remove his mask, trapping him forever. If Jarvis survives the player will need to talk to him and then Death to collect the reward, however if Jarvis dies the player only needs to talk to Death to claim the reward.

- This event was the first Old School RuneScape quest where player interactions affected the outcome of the survival of an non-player character.
- The event makes many references to films and media in popular culture:
- At the beginning of the event, The Grim Reaper mentions he "feels a disturbance in the force". This is a reference to the 1977 film, Star Wars, directed by George Lucas and later renamed Star Wars: Episode IV – A New Hope.
- The name Jonas is an anagram of Jason, which, alongside his appearance and character, is a reference to Jason Voorhees from the Friday the 13th series, specifically the original films.
- The item Death note is most likely a reference to the 2003 Japanese manga series Death Note (デスノート), written by Tsugumi Ohba and illustrated by Takeshi Obata.
- The music that plays while on the island is an homage to the theme of director Stanley Kubrick's 1980 horror film, The Shining, composed by Wendy Carlos.
- Throughout Jarvis's house, the piles of books that players search around the sofa have the titles "Bride of Fenkenstrain", "A Nightmare of Elf Feet", and "The Helda Witch Project". These are references to Bride of Frankenstein, A Nightmare on Elm Street, and The Blair Witch Project, respectively.
- The interaction text for the table in Jarvis' house, "This table looks like it would break if moved. You could say this is its final destination", is likely a reference to the 2000 James Wong film, Final Destination, and its subsequent sequels.
- The interaction text for the bed in Jarvis' house, "A place to sleep when darkness falls", is likely a reference to the 2003 horror film, Darkness Falls, directed by Jonathan Liebesman.
- While interacting with the rusty range in Jarvis' house, it is described as being "exactly the type of thing that you would expect to see in a cabin in the woods". This is a reference to the 2012 horror-comedy film, The Cabin in the Woods, directed by Drew Goddard.
- While interacting with the pottery in Jarvis' kitchen, it is noted that the pots are just standard affair and that "you can see no sign of paranormal activity". This is a reference to the 2007 found-footage horror film, Paranormal Activity, directed by Oren Peli.
- While interacting with the old sofa in Jarvis' house, the player reconsiders as the thought of sitting down on the sofa gives them "goosebumps". This is a reference to the horror-fiction novels Goosebumps, written by Robert Lawrence Stine.
- While opening the fridge in Jarvis' house, the player muses that they don't want to see what happens to the decomposing food "28 Days later". This is a reference to the 2002 post-apocalyptic horror film 28 Days Later, directed by Danny Boyle.
- The unmasking of the villain at the end of the event is a reference to 1969 children's animated television series Scooby Doo, where each episode ended with the main characters unmasking the villain the team was investigating.
