Enter the cave and use side passages with rockslides to bypass centre swampy path.
Talk to Koftik for a cloth. Use it on an arrow, then light it.
Make sure you are standing around the bend to the north. Equip your bow and the lit arrow. Shoot (click) the guide rope attached to the bridge.
The plank for passing some traps further in is located just after the bridge to the right (north). Only one is needed.
Continue through the cave until you reach a gap. Use a rope on the tiny 'Old spike' at the edge of the gap.
Continue through the cave over two rockslides until you reach a large grid.
Find your path across the grid. Keep a record of the path over the grid for Regicide quest. You will fall through some of the tiles. Pull the lever to the south at the end.
Orbs of light
Run past the zombie camp, there will be odd markings along the walls of the corridor. These are traps, disarm them.
You will reach an altar, take the north path using planks on the flat rocks. Take the orb.
Take the north-west path. Take the orb.
Take the west path, traversing the flat rocks as before. Take the orb.
Take the final path, don't pick up the orb. Search the rock underneath the orb to disarm the trap and take the orb.

Use the 4 orbs on the furnace.
Return to the altar (again, don't forget about the traps), and climb down the well.

Cold blooded killing
Search the unicorn cage to find a railing.

Kill them and take their badges.
Continue forward, using your plank on the flat rocks, until you see a well.
Use the badges and horn on the well.
Use the door.
Head south along the wall to the south-east corner then head west along the south wall to find the stairs there. Take the stairs down. There are also stairs in the north-west corner that may be easier to find but will require players to make their way through the herd of hostile soulless in the centre of the cavern below on the way to the dwarf camp.
Run to the dwarf camp in the cavern's south-western corner and talk to Niloof the dwarf.
Go back up the stairs and pick up the Witch's cat, the cat should be wandering out on the bridges and platforms north-west of her house. The Witch's house is the most south-eastern platform.
Use the cat on the Witch's door.

Run to the north-east corner, kill Kalrag the spider.
Go to the north-western corner and ascend the stairs to the half soulless area.
Walk south to the third walkway and cross the bridge. Walk north to the first cage, then walk east to the next cage. Walk a little north then west from here to the cage containing Iban's dove (lowest platform in the centre of several others). Wear Klank's gauntlets and search the cage to find Iban's dove.
