Official description Edit

“	Things are not going well for the Catapult Guard at the Tyras Camp. Already unpopular with his comrades after his security lapses, he's now neglected the catapult and allowed the damp of the forests of Isafdar to seep in and rot the frame. General Hining is furious, the replacement catapult parts haven't arrived and the rookie catapult engineer has gone missing. It's a good thing, then, that a bold adventurer with your knowledge of Construction is in the area. Of course, this will take more effort than forming furniture - catapults are complicated pieces of equipment - ensuring that this mission will mean your exertions will be mental as much as physical.	”

Reaching Tyras CampEdit

There are many ways to reach the Tyras Camp :

• Using a charter ship from almost every dock is BY FAR the fastest, safest, and easiest way.
• Using a crystal to Lletya and walking to Tyras Camp through the dangerous forest.
• Via the Underground Pass and walking through the dangerous forest to the Tyras Camp.
• Via Arandar and walking through the dangerous forest to the Tyras Camp.
• Accepting the quest from Alfred Stonemason.

Starting the questEdit

Speak with the Tyras Guard north of the Tyras Camp. He will explain that General Hining may be wanting to remove him from the job, as he has not been treating the wood properly. After an unsympathetic conversation he asks you for help. He needs someone with more experience in Construction to help him repair the catapult. Tell him you will help.

Head to the camp and speak with General Hining. He will explain that the catapult is an essential part of the camp's defence, and that having it down could mean disaster for the camp. He will give you permission to help repair the catapult. He also says that he will need you to find the missing engineer, whom he suspects may be somewhere in the forest. He will also give you an Engineer's letter to bring to him. If you lose it, speak to General Hining again.

Finding the Catapult EngineerEdit

Items recommended: Food, Antipoison

Find the Catapult Engineer. He is located in a clearing filled with Pawyas, north of the Tyras Guard. To find him, head south-east from the catapult. Just south of some Grizzly bears is a dense forest. Pass through the dense forest. It is here that you will need to have food, as there are traps.

Jump the tripwire (they hit for a few hundred). There are Grenwalls in this small clearing. Head east to another dense forest and pass it. Beware of traps that you may need to pass.

You will now be in a little glowing blue mushroom clearing. Head north-west past the rabbits. There will be a 2nd group of rabbits and then a Leaf jump. Go north where there will be bears and pawya. To the west, search for a little path between the trees that leads south to the Engineer. Be careful of the Stick trap! There is a hunter symbol on the mini-map.

Speak with the Engineer and offer your assistance.

Read the Catapult schematics you get from the engineer to see what materials you will need, then talk to the engineer again and ask to see the letter. Read the letter to find out what kind of materials you need.

You will need:

• 90 Mithril nails
• 10 Mahogany planks

Once you have all the parts, read the schematics and choose to make the repair parts.

After making the parts, talk to the engineer and ask him to let you read the letter that you gave him earlier. Speak to him again and ask him about Rolad.

Getting the catapult repair partsEdit

Find Rolad in the east building at the entrance to the Dwarven Mines on the edge of the Ice Mountain. He says that he has already sent a delivery dwarf to Port Sarim with the catapult parts.

Head to Port Sarim, where you will find Thaki the delivery dwarf in the Rusty Anchor pub north of the docks. Speak to him and try to get him to give you the metal catapult parts. However, he will refuse since you are not striking him as a sailor. Search the Drunken Sailor outside to get a sailor's hat. Alternatively a tricorn hat from the naval outfit will also work. Wearing the hat, speak to the delivery dwarf again (who happens to notice the difference). This time you will get the metal catapult parts.

Note: While the mahogany parts take up 10 slots, the metal parts only take up one.

Repairing the catapultEdit

Bring the Metal catapult parts, Mahogany catapult parts, and tools (saw, hammer, knife, toolbelt will work) to the Tyras guard and talk to him to start repairing the catapult.

To repair the catapult, you will have to fit the different pieces of the catapult in a tetris-like puzzle. There are two sides: an orange and a purple side. Both require certain pieces to make it work. There are many possible combinations to fill out one side, but it may not leave you with the correct pieces to complete the other. The following two pictures show the correct piece placements.

Orange Side

Purple Side

Controls

Click on a part to make it appear on the screen. Use the directional arrows to move it up/down/left/right, the circular arrows to rotate it clockwise/anticlockwise, the yellow curved arrow to select the opposite side, and the green sunburst button to restart.

Testing the catapultEdit

Once you have solved the puzzle, you have to test the repaired catapult. You will have to hit three stones with an 'X'. Increasing the counterweight causes the stone to fly farther; decreasing the counterweight causes it to strike nearer. For example, to hit the closest boulder, you want to have just one bar of blue showing. This part is fairly easy compared to the other puzzle. It requires a small amount of trial and error, but can be quickly finished.

• The center rock requires 1 blue bar (hit the left counterweight arrow all the way down).
• The left most rock requires 6 blue bars (hit the left counterweight arrow until you can't hit it anymore, then hit the right counterweight arrow 5 times).
• The right most rock requires 7 blue bars (after hitting the left rock, move the counterweight arrow right once).

Catapult fire controls

Move Counterweight to left (decrease weight) for closer distance or right (increase weight) for farther distance. Use Direction to move left or right. Red button to fire. "Target hit! The rock shatters as your shot smashes down."

After hitting all the rocks, talk to the guard again.

Congratulations! You have completed Catapult Construction!

TriviaEdit

• On the first day of release, if players clicked to see the spoilers, they received the message: Alas, it seems the Tyras guard looking after the reward list has misplaced it. Check back tomorrow.
• On the day of release of the quest, all servers failed due to unknown reason, and the forum post rate went up to more than 1000 posts per second.
• This quest is Master class, along with Mourning's Ends Part II and Desert Treasure, and yet appears to be of roughly Intermediate difficulty. This tells that the level classification is based on the pre-requirements rather than the quest itself.

  

• Upon the completion of this quest, one's Adventurer's Log will read: "I’ve helped the Tyras Camp - for a change - by repairing their rotten catapult. Their catapult engineer was useless!"
• After completing the quest, if the player talks to Juna, their character will say, "...And that was how I repaired the catapult in the Tyras camp." to which she replies, "Catapults are terrible devices. They move rocks from their proper Guthix-assigned positions."
