The Vault of Shadows

You will need to activate four buttons within the dig site. After activating each button you will be able to enter the corresponding door and complete a puzzle. While the buttons may be activated in any order, the puzzles are always received in the same order.

You will need to activate all shadow anchors or wait until the Pylon is active to do the 4th puzzle. If you don't have a ring of visibility or have the ability to permanently see the Shadow Realm, this is also required for a step after gathering 500 divination memories.

You will need 80 batteries to charge all eight anchors. You can get these batteries by excavating in Kharid-et Dig Site or by doing Zarosian I collection for Soran, Emissary of Zaros in Varrock. He will give you 20 batteries each time you repeat the collection (after the first time).

Head into the prison block section of the dig site.

Enter the eastern door which leads to the solitary confinement area.

If you haven't completed Time Served but you have the repaired artefact in your inventory, then just inspect the ancient mechanism to the North. Insert the artefact and then the eastern door will open.

Go down to the southern end of the corridor, there will be an inactive dial on the west wall, just before the last empty room.

Cast an 'Incite Fear' spell scroll whilst standing next to the dial.

Press the ice button and enter the vault

Pick up the praetor's log page 1 and right click Transcribe.

Set your compass to face north (so the central vault is on the east of the screen).

Using the image, press each button in order. Backwards turns are denoted by '. For example, SW' means turn south-west back.

You may cancel pressing the wrong direction (e.g. SW instead of SW') by pressing the same button in the other direction (e.g. SW'). You can then proceed with the right move (e.g.SW').

If you make a mistake, you can leave and return via the button on the western wall to reset the puzzle.

To leave, you can use the Vault exit to the east.

For the shadow button, you will either need to have activated all the shadow anchors or wait until the Kharid-et pylons are active.

You will need 80 batteries in total to charge all 8 shadow anchors.

To quickly obtain batteries, you can repeatedly complete the Zarosian I collection for Soran, Emissary of Zaros in Varrock. He will give you 20 batteries each time you repeat the collection (after the first time).

Normally, it's best to charge the shadow anchors first (since you will have to charge it sooner or later anyway, you might as well do it now).

However, if the power tower is about to activate (90% or higher), you can consider waiting. Even so, you should use all the batteries (10 of each) to charge the shadow anchor instead of the pylon (because 10 batteries only increase the activation progress by 0.01%), just in case you cannot complete the charging within 30 minutes.

Return to the Main Fortress of the Kharid-et Dig Site and enter the war room by clicking the praetorium war table (middle of the Main Fortress)

Find the inactive dial on the western wall in the small western room.

Cast an 'Animate Dead' spell scroll whilst standing next to the dial.

Press the Shadow button and enter the vault

Set your compass so that it is facing south (so the central vault is at the top of the screen).

Using the image, press each button in order.

The final combination of the dials on the wall is, from top to bottom: shadow, blood, smoke, ice.

The door and now the vault will open.

Pick up the shadow engrammeter (depleted) from the centre of the vault.

Collect 500 divination memories (vibrant tier or higher). Recharge the Shadow engrammeter when you have an inventory full of memories to charge it. Enriched memories count as double.

Return to the centre of the vault via any of the dials and Operate the engrammeter.

Take Trindine's memory to Dr Nabanik.

You will receive the memory as a book, and be granted 25,000 Divination experience.

Return to the vault using any of the dials.

Speak to Praetor Trindine in the centre. This will complete The Vault of Shadows mystery.

If the shadow anchors weren't activated, or Pylon isn't active, you will need to wear a ring of visibility or have the ability to permanently see the Shadow Realm.

Return to and speak to Dr Nabanik.

Speak to him again after the cutscene.
