Horror from the Deep

Horror from the Deep is an experienced quest revolving around the mysterious disappearance of Jossik, keeper of the Lighthouse near the Fremennik Province. As the title suggests, the investigations lead to the discovery of very dangerous creatures living beneath the lighthouse.

Unattended
Travel to the Lighthouse by using an enchanted lyre, a games necklace teleport to Barbarian Outpost, a Teleport to House, if your house is in Rellekka, or any other method that you wish. Start the quest by speaking to Larrissa, who can be found standing just outside the lighthouse entrance.

Larrissa tells you that she thinks that her boyfriend, who resides in the lighthouse, has gone missing as she hasn't seen him for a few days. To further her fears, the light is switched off and the front door bolted shut, which she says is unlike him.

Diary of the.. Presumably Dead
When you offer to help search for her boyfriend, Larrissa suggests you speak to Gunnjorn at the Barbarian Outpost for a spare key to the lighthouse and also fix the broken bridge to the east.

To be able to enter the agility area and talk to Gunnjorn, you must have completed the miniquest Bar Crawl.


 * Travel to the outpost by either using a games necklace teleport or by going south, across the basalt platforms. Talk to Gunnjorn at the start of the agility course and get the lighthouse key; you can get two planks here; they respawn just north of the outpost.
 * With a hammer and 60 steel nails in your inventory, use the planks on both sides of the broken bridge located east of Larrissa, shown in the map above. You can cross the broken bridge by doing a small jump, so just hop to the other side and fix that part of the bridge.

Go back and talk to Larrissa again, who now tells you to enter the lighthouse and search for Jossik. Inside the lighthouse, climb to the first floor and search the bookcase. Retrieve and flip through the lighthouse manual, ancient diary and Jossik's diary, which tells you about the history of the lighthouse and its inhabitants.


 * On the top level, use molten glass, swamp tar (not swamp paste) and a tinderbox on the lighting mechanism. The lighthouse will now be fixed.

Elementary
Go down to the basement of the lighthouse, where you will find a small cavern with a strange wall, having six empty slots fitted into its frame.


 * Use all of the basic elemental runes on the wall, (fire, water, earth, and air)
 * Use your sword and your arrow (any type, but remember that you will not get them back).

Warning: This is your last chance to prepare for the fight.

Preparation
If you haven't prepared for this fight with armour and runes for casting magic, teleport to any place with a bank to ready yourself. If you only brought a games necklace, then use it to teleport to the Gamers Grotto or Burthorpe Troll Invasion and bank there. While you are there, you may wish to pick up any quick teletab to any city or your POH, just in case you are close to death, to save yourself.

Inventory

 * It is recommended to bring at least two types of attack styles, that is, either magic, melee or range.
 * Bring good armour (at least rune equipment, dragon hide armour, or mystic robes), enough combat runes to cast several of each elemental spell (wind, water, earth, and fire). If possible, equip a ring of life and bring a one-click teleport just in case things get messy.
 * Stock with prayer potions and a super set.

Combat
If you cannot see the colour changes very well, look to the chat box. There would be a message "The Dagannoth mother turns (colour)..." Also, you can change the graphics to "safe mode" to brighten the scene, allowing you to see her colour clearly. Using the wrong type of attack incurs splash damage.


 * By default, her first form is always white. The cycle of the colour changes of the Dagannoth mother seems to be totally random.
 * She can detect prayer and will automatically switch to an attack type different to your protection prayer. By default, she ranges at a distance and melees up close. She can hit up to 160 with melee and accurate, double-120s with ranged, so Protect from Missiles/Deflect Missiles is recommended.
 * If you stop attacking her at any point or take too long to finish her off, there is a possibility that she will disappear and you will have to start the fight again.
 * If a player has reasonable defence, they could consider using attack-boosting prayers instead, because the Dagannoth mother has a rather poor accuracy.

Get ready to face the mother!

The Horror
Once you are ready, walk through the unlocked wall and down the ladder. You find Jossik alive, but hurt and resting against the dungeon wall. He tells you that his search for his lost uncle, Silas, had brought him past the secret door, but he was attacked by a monster who was able to trap him there.

As he is talking, he announces that the monster is coming back. A cutscene plays where a dagannoth appears from the water. The monster can be fairly easily disposed; put on protect from melee and range or melee it, as you need to save your runes for its mother.

After you defeat it, try to help Jossik up to the surface, but he tells you that that wasn't the monster that had attacked him. A cutscene will show the Dagannoth mother emerging into the cavern, and engaging you immediately into battle.

The God Books
After you defeat the Dagannoth mother, Congratulations. You have survived the Horror from the Deep!...once.

As a reward from the Dagannoth mother, you obtain a rusty casket. Go to the first floor of the lighthouse and show it to Jossik. If you had a full inventory when defeating the Dagannoth mother, you will not receive a rusty casket. Instead, you must talk to Jossik, who will have picked it up for you.

You may now choose a book affiliated with three gods: Saradomin's Book of Wisdom, Guthix's Book of Balance or Zamorak's Book of Chaos.

Trivia

 * The quest was originally named Lighthouse Quest.

 * It is impossible to obtain a book of Armadyl, Bandos, or Zaros as a reward for the quest. You can only choose to buy those books after you obtain and complete one of the three books of Guthix, Saradomin or Zamorak.
 * With the release of Legacy Mode, the combat level of most monsters and NPCs were scaled down. While the Dagannoth Mother was downgraded from 120 to 84, the Baby Dagannoth remains at 100.
