Required:

Skills: 20 Crafting, 25 Thieving.

Items: Desert robes and Boots, waterskins, pestle and mortar, papyrus (sold in Al Kharid at Ali Morrisanes general store or in the east ardougne general store), empty vial, 4-6 Soft clay

Suggested: Hammer, Rope, Chisel, Pickaxe, Varrock teleport and Ring of Duelling, optional to save you from running around. A Bracelet of clay with at least 4 charges will allow you to mine soft clay without needing water.

Buy at least 8 buckets/bowls/jugs of water from Shantay and take your pickaxe with you. Somewhere east of the pass are clay rocks, mine 4-6 of them and make them soft by using water with them (if you are not wearing a bracelet of clay).

Wear your desert gear and bring the waterskin(s). Buy a shantay pass from Shantay (5gp), go through the pass and walk east till you reach the coast. Follow the coast south. You will come to a bridge. Cross the bridge and go east until you come to some ruins. The broken golem is pacing around this area. Talk to him.

The Golem will tell you he needs repairs. Use your 4 soft clays with him. Talk to him again. He will ask you to help him open the portal to slay a demon. Talk to him again and he will tell you to arrange the statues down the stairs next to him.

Go down the stairs and forward a bit. You will come to a square with two walls, two alcoves on each containing a statuette. One statuette is missing. Turn the statuettes on the west wall so they are facing left and the statuette on the east wall so it is facing right. Go upstairs and west, lying on the ground next to some crates is a letter. Pick it up.

The letter is from Elissa. Elissa is at the north end of the digsite. You may wish to teleport to Varrock or Al Kharid to save some walking. When you use the letter with her she tells you to find some expedition notes in the digsite exam library.

Go south to the exam center and search the small cluster of bookshelves on the south side against the wall until you find Varmen's notes. This took me about 15 tries before I found them. Read them. Go back to Elissa and ask her where he took the statuette. She will tell you it is at the Museum of Varrock.

Walk over to the museum which is located north-west of the Varrock east bank. Talk to the curator about that statuette. He will say it is up in a cabinet upstairs, but won't let you have it as what you have in mind sounds too dangerous. Pickpocket him. You will get a key which you can use with a cabinet upstairs to get the statuette.

Go back to the golem and down the stairs. Place the statuette in the empty alcove by using it on the alcove. Turn it so it is facing right. The door will open. Go forward and enter the door. You will find the demon is but a skeleton and must already have been slayed. At this point you can use your hammer and chisel on the throne to get several gems. Go through the red, swirly portal to get back to the statuette place. In the northwest corner you will notice a key shaped object called "strange implement". Pick it up. Also, while you are down there pick a black mushroom, use it with the pestle and mortar to automatically get black mushroom ink in your empty vial.

Speak to the golem, he will insist the demon needs to be slayed and his task is incomplete. You need to write him a new program. Go north of the ruins and then follow the sea until you come to some clay rocks and find a desert phoenix. Click on it to get a feather. Sometimes it will stun you, but keep trying till you get a feather. Once you have it, use it with the black mushroom ink. After that, use the quill-pen with the papyrus to write the golem a new program. Go back to Uzer. Use the strange implement with the golem to open his skull and use the program on him. Talk to him. He will say his task is completed. You have now completed the quest, congratulations!
