Juna asks you to condense some Dozurite to power some lamps inside of Solusek's Eye, to power the big machine in the front of the giant crater.
Go down to the area with the magmatic golems, titans, and sentries ( -166, -225, 48 ) /waypoint -166, -225, 48 (Level 4). The golems start if you go through the teleporter to the giants and then head east back to the entrance.
If you get two golems be sure to kill the un-condensed one first, as you have a very short time limit for the next part!
When the dozurite golem dies he will drop a harvestable dozurite. It will disappear very quickly, so gather the dozurite fast. A Compact Sumac Harvesting Kit comes in handy (reduces harvesting time by 2.5seconds).
Once you have 30 dozurite find a large refining machine to convert your dozurite to refined dozurite. It takes three unrefined dozurite to make one refined dozurite. There are several machines throughout the golem area, for example:
( -5, -250, 33 ) /waypoint -5, -250, 33
( -259, -239, -40 ) /waypoint -259, -239, -40
( -32, -240, -6 ) /waypoint -32, -240, -6
Once you have the 10 refined Dozurite go to the tall lamps and insert the dozurite by right-clicking on them. They look like old fashioned street lamps with a glowing yellow light and are scattered throughout the upper part of Sol's Eye. Not all the lamps are clickable.
(Presentation order here is from bottommost lamp towards the top of the zone; you can do the lamps in any order. Sublevels refer to sublevels as seen on EQ2MAP.)
Now you need to turn on the power generators so you can re-imbue the cloak. Go to the large hole near the zone entrance. On either side of the hole by the ramps at ( -104, -11, -18 ) /waypoint -104, -11, -18 and ( -104, -11, 68 ) /waypoint -104, -11, 68 there will be a lever. Click them both to route power to the machine.
Now go to the middle of both levers where there should be spinning gears ( -69, -12, 25 ) /waypoint -69, -12, 25 and click the center of the machine to get the final update.
