Master Engineer Yor has constructed a door puzzle near the Pargrun Cache in Shatterscarp that seals away the Sigil of the Arcane, one of the best Rings in Avowed.
Puzzle Location
This puzzle is located at Shark’s Teeth in Shatterscarp. To unlock the door, you have to activate the three stone tiles above it. Each one is connected to a device nearby that you have to power with electricity.

How to unlock the door
The first device is on the ground, south of the door. As you face the door, turn left and you will see it at the base of the old tower ruin.
The other two are up on the bridge above the door. As you are facing the door, head right, up the hill and climb onto the wooden scaffolding.
Before you climb on top of the bridge, go around the wooden scaffold and on its left side, you will see the second device hidden.
The final device is on the bridge. Climb up one more of the wooden scaffolds and look to your right. The device is to the right of the staircase.
Reward: Sigil of the Arcane Ring
Inside the small room, you will find a lockbox containing the Sigil of the Arcane Ring and a Heartfelt Note next to it on a stone table.
Thaumaturge’s Expertise
+20% Ability Cast Speed
-20% Ability Essence Cost
The Sigil of the Arcane is one of the best rings in the game, especially for Wizard builds, as it lets you cast spells 20% faster and makes them cost 20% less Essence (mana). Even for Fighters and Rangers, the -20% Essence Cost is quite significant.
While they only provide half of what each Attribute does, both components of Thaumaturge’s Expertise are equivalent to ~5 points of Dexterity and Intellect without being subject to severe diminishing returns.
