Description: The lighthouse protecting Kandarins North Western coastline has mysteriously stopped operating, and contact with the lighthouse keeper Jossik has been lost. The Council would greatly appreciate it if somebody could discover for them what has happened to this most vital landscape feature.

Start point: Lighthouse north of Barbarian Outpost.

Quest Length: Short-Medium

Quest Difficulty: Medium (two level 100 monsters, with the second one being rather difficult if you are a lower level, I was level 82 and had a tough time with him, MrStormy)

Items/Skills Needed to Start: Level 35 agility, must have completed the barcrawl portion of the "Scorpion Catcher" quest, ability to defeat a tough level 100 monster, 1 molten glass, tinder box, 1 of each: air, water, fire, and earth rune, 8 nails, 2 planks (can be gotten from near barbarian outpost), 1 swamp tar (not paste, get the tar from lumby swamp), hammer, 1 arrow (any kind), 1 sword (any kind but you will not get it back, so use steel or below)

Reward: 2 Quest Points, a prayer book, 4k range, magic and strength experience

Part 1: Fix the Lighthouse

1. Go to the lighthouse area and talk to Larissa.

2. Go down south of her across the jumping platforms and into the barbarian outpost to talk to Gunnjorn and get the light house key (if you don't already have planks get them here).

3. Use the two planks on the broken bridge east of Larissa.

4. Go back and talk to Larissa. After talking to her go into lighthouse.

5. Go up one level and search the book case; take the books read the lighthouse manual and the diary.

6. Go up one more level use the swamp tar with lighting mechanism and then use your tinderbox on it, then use your molten glass on the lighting mechanism.

7. Go back down and talk to Larissa

Part 2: The Door

1. Have the runes, arrow, and the sword in your inventory and go down the ladder and walk over to the strange wall.

2. Use your arrow, air rune, earth rune, water, rune, and the weapon on the strange wall.

Note: You will not get any of this stuff back.

2. Open the strange wall and climb down the ladder, and talk to Jossik.

Part 3: The Monster from the Greyish-Green Lagoon

1. Fight and kill the baby level 100 monster that attacks you (quite easy with protect from melee).

2. After the first baby is killed another level 100 monster attacks you.

It uses a form of the prayers and changes colors to show what it is weak to:

Light brown means you can melee.
Green means you can range.
Red means you can use fire spells.
Dark brown means you can use earth spells.
Blue means you can use water spells.
White means you can use air spells.

It also attacks with both range and melee attacks, the range attack is weak so always use protect from melee.

3. Switch between melee, range and magic as the monster switches colors. Just keep your prayer up and you keep an eye on your hits.

Part 4: Quest End

1. Quest finished when you kill the second monster you will be automatically transported out of the room and you will see quest completed. You will get your exp, quest points and a rusted coffin.

2. Go up to the second story of the light house, Jossik is now there. You can buy most ales and some other stuff off him. But for now talk to him, he tells you to read what it says, pick the same god twice.

3. I picked Zamorak and got an unholy book of Zamorak, which gives a +5 prayer bonus and goes into shield spot.

Strategy of Horror From The Deep

Skill Recommendations

• 43 prayer (protect from melee)
• At least level 50

Item Recommendations

• Prayer potions
• Full range (min red) or rune armor
• Best melee weapon and best range weapon
• Runes for magic spells (strike spells min.)
• Air runes and law runes so you can teleport back to Camelot if need be

Part 1: Fix the Lighthouse

1. You can bring most everything you need with you. Bring a couple pieces of food incase you get hurt on the agility obstacles. It will also make your life easier if you bring teleporting runes.

2. You can also bring all the stuff you need for part 2.

3. High levels can also bring food and prayer potions for part 3.

Part 2: The Door

1. If you brought the stuff for part 2, use it all in the door.

2. If you brought armor, potions, food just continue on, otherwise walk or if you brought runes teleport back to seers.

Part 3: The Monster from the Grayish-Green Lagoon

1. Make sure your health is up as is your food, then talk to Jossik. After a few things he says a monster will come out of the swamp with an arrow over its head, attack him.

2. This monster is level 100 but is rather easy, you should be able to defeat him with melee in no time.

3. After you defeat the baby monster, the mother comes out of the ooze. She is a lot bigger, but is the same level. She changes color as you fight, so switch your weapons respectively. You don't need to use magic I defeated her by switching between melee and range attacks.

4. She attacks with both melee and range, but the range attack is weak against ranger armor, so I suggest using protect from melee and eating to heal the range attacks.
