The Hand in the Sand/Quick guide

Sandy Hand
Items Needed: Beer (Obtainable during quest)

After starting the quest by talking to Bert (Yanille), you will receive a sandy hand. He's afraid it will cause him some kind of trouble, and wants you to investigate it. He'll tell you to go talk to the captain of the guards. He hangs around the inn in Yanille. Take the hand and a beer to the captain of the guards in the Ye Olde Dragon Inn. He will ramble on and then he'll take a look at it and simply drop the hand in his beer, turning it into a beer soaked hand. Go to the Wizard's Guild, just east of the bar and ring the bell to make Zavistic Rarve come out. Talk to him and explain the situation. He will tell you that this is the hand of one of his wizards. He'll ask you to see if Bert's working schedule has changed recently.

Sandy the Slavedriver
Items Needed: Bert's rota

Return to Berts home, and talk to him again. He'll tell you that he works for Sandy Sand Co, which is based in Brimhaven. He'll give you a copy of his schedule and tell you that it hasn't changed recently, or so he thinks. (Or has it?) Now you need to head to Sandy in Brimhaven. You can go to Ardougne and pay 30gp to get to Brimhaven. Sandy is located in the office just north-west of the Dead Man's Chest bar.



In Brimhaven, you'll see Sandy in his office. You can talk to him first if you want, but this isn't necessary. Search his desk in the house to get Bert's old schedule. Read it and compare it to the other schedule to see that Bert has indeed been working longer hours. While you're here, pickpocket Sandy to find some sand in his pocket (this may take multiple attempts). Keep it; it will become important later on in the quest.

Truth Serum
Items Needed: White Berries, Red Berries, Lantern lens, Sand (Pickpocketed from Sandy), 2 Empty Vials.

Now you need to visit Bert once more. Talk to Bert in Yanille to find a scroll that appeared in his house recently. It appears normal, but do not throw it out.

Take the scroll to Zavistic Rarve to learn that it's a mind altering scroll, and it was a trick to change Bert's hours without having to pay him more money. Now that you know that Sandy is behind it, you need to first get Betty in Port Sarim (Zavistic Rarve can teleport you there as explained below) to make you a truth serum, then videotape Sandy using the orb that you're given while he's on the serum.

Take a vial, the redberries, the white berries, and a lantern lens, as well as the sand pickpocketed from Sandy's pocket with you to Betty's magic shop in Port Sarim. Alternatively, take these things plus an extra empty vial to Zavistic Rarve and he will teleport you directly to Betty's shop.

Betty will take the vial and give you a sample bottle of water. You need to add redberries, then white berries to make pink dye. Once you've made some, use it on your lantern lens to dye it pink in color. Talk to Betty again. Then stand in the doorway and shine your lens at the counter (click on it in your inventory, then use it on the counter) to fill up a vial with truth serum. You now need a personal item from Sandy to fill up the vial. Talk to Betty again to use the sand you previously found in Sandy's pocket. Give it to Betty to finish the serum.

Sandy Truth-Be-Told
Items needed: Truth Serum

Back in Brimhaven talk to Sandy. Get him distracted by talking to him and selecting the 'pygmy shrew' option (This option may not work; try the others). Once he looks out the window, use the Serum on his coffee. Then activate your orb and talk to him. He'll confess that he bribed a wizard to put a mind altering spell on Bert. He then changed Bert's schedule so that he'd work longer for the same pay. Afterwards, Sandy killed the wizard so that he wouldn't have to pay him, then he buried parts of him in all of the sandboxes around RuneScape.

And Sandy said, "Drat- foiled again!"
Items Needed: 5 Earth Runes, A Bucket of Sand

Back in Yanille, talk to Zavistic Rarve. Give him five earth runes and a bucket of sand. He will then cast a spell on Bert's sandbox so that it'll fill itself to compensate Bert for his troubles. Then go to Entrana. Talk to Mazion by the sandpit to get the dead wizard's head. Give this to Zavistic Rarve. He'll confirm that it belongs to Clarence, and the quest is complete.
