This dungeon is restricted to level 50+. You'll need a large group for both the upper and lower side to finish this quest. At the lower portion of the quest you'll acquire the shiny Lightning Prism whereas the upper side gets the bracelet.

Split into two teams before heading into the dungeon. Take the Artifice settlement portal (32.9N 59.4E) from the Arwic Settlement portals then it's a small run from the drop. You can also take the Artifice settlement portal from the Arwic Settlement portals. The run is pretty quiet and short so there's no need for a full buff. Head to the Emprean Lightning Propylaeum at 87.1S 9.6E. Inside the dungeon you'll be greeted by 4 Olthoi Nobles. Clear them out and take the passage down. You'll be swarm by olthois. Clear them out and make a small jump down the acid pit and quickly leave it before it kills you. Watch out for Olthoi Nobles and Olthoi Eviscerators. Have everyone grab a hammer from the West hall chest then head South. Continue forward to the portals. Be prepare for more Olthois. Note: the prism is from the lower section and the bracelet from the upper. Head into the two portals and rebuff in there if you must.

Lower:

• Be prepare for war before you enter the portal. Head forward and you'll come have a choice of going left or right. Turn right and you'll find your first lever for the other team.
• Once they got through the door head back to the left side where you'll find your first door. Inside you'll find the 2nd lever.
• Head back to the 1st lever and continue heading forward (North).
• Continue forward to the Y intersection. Make a right then hang left to the lever.
• Exit the room and hang right to the 2nd door.
• Hand left to the next door and wait for other team.
• Continue heading forward (South) till you come upon the lightning pit. This door is much easier to see than the other 3 prism dungeons.
• Note: Angle your camera to view the door and jump after it's open.
• Note: There are 3 traps in this small room so watch out for your spells and mana.
• Proceed to the next large room and you'll see an iron door. This is the final door you have to go through. Once inside clear out the mob and head to the prism. If another run is expected then wait till everyone has their prism and have the other team pull the last lever to gain access to the exit portal.

Upper:

• After going through the first door head North to the next room. Hang left to find the first lever.
• Return to the large room and go through the door at the South hall after the other side pulls the lever.
• Proceed to the 4 way intersection and head up the North ramp to the 3rd door.
• Hang right to the room with the next switch for the other team which is a button on the wall.
• Head back to the previous room (with the door you went through) and take the West stairs up.
• Right before you get to the next big room continue heading forward and you'll find the 3rd button on the left wall of the dead end.
• Clear the room and continue forward and make a sharp right turn at the next intersection to find the 4th lever. This is the one above the lightning pit.
• Now continue heading forward (South) to the room with the gratings and you'll find the last and final lever to the right of the room on top of the grating.
• The bracelet is inside the room with the exit portal. If another run is expected wait here to pull the switch for the other team to get access to their exit portal.

Take the Fragment of the Lightning Prism to an Agent of the Arcanum and you'll get 500,000 experience, 2 Writs of Refuge and the Craftable Prism Fragment of Lightning. The prism can now be drop/transferred. Note: You can only get writs on turning in your first Lightning Prism.
