Horror from the Deep

Return to Quest Guide

Items Needed: A prayer pot and some food (Swordfish+), multiple combat styles and decent combat skills.

Skill Requirements: Able to defeat Level 100 Dagannoth Mother.

Rewards: Able to equip, choose and buy all the God Books.

Start up using your Quest Orb, you'll be far west from Relleka, you'll need to go to the Lighthouse even more west from where you are. Eventually you'll see Larissa, which needs help desperately, she asks you to find a key that can get you inside the Lighthouse, her cousin Gunnjorn can help you.

To get to him, you'll need to to Edgeville using your Home Teleport, go to Wizard Mizgog and go to the Barbarian Agility Course (Skilling > Barbarian Agility Course)

Speak to him and he'll agree to help, by giving you the Lighthouse Key.

Now it'd be a good moment to grab either multi-combat styled gear (Melee & Ranged & Magic), or just grab Melee and Ranged (this is what I did, but it's really up to you), use your Orb to get back to the Lighthouse talk to Larissa and give her the key, you can now go inside the Lighthouse, enter and go down the ladder.

Go past the door and go down the next ladder, you'll meet the Dagannoth mother below.

The Dagannoth mother is special, since her colors show her weakness, for example, if she's White, she'll be weak to Air Spells, here's a list of her colors weaknesses:

White = Spells, Orange = Attacks, Blue = Spells, Red = Spells, Green = Attacks, Brown = Spells

She has only 100 hp, if you have prayer you could use Anti-Melee, if you only have Melee and Range on you, just stand on her until her colour is Orange or Green to damage her, once you kill her, the quest is complete.

She'll drop a casket containing one of the 3 God Books, the best choice is to pick the Unholy one, but you can always have more books, all you need to do is teleport home and go to the man hut. There is crate located beside the bank chest, you can purchase as much books as you would like from there.
