This is a walkthrough of the Enter The Kobold puzzle/maze based on an image from DDOWiki uploaded by Yoko5000. Whether any other disclaimers or attributions are in order, I don't know.
The puzzle should be completed by only one person. The rest of the party should pike until the puzzle is solved, so that everyone can move freely through the puzzle without resetting any of the pieces. Once it's completed and the party is safe on the other side, you still have a tough boss fight to look foward to, which is not covered here.
You begin in the SouthWest corner of the puzzle, just below the 4x4 grid of puzzle rooms. When the puzzle is complete, you will exit from the NorthWest corner. The rooms within the grid will be named according to rows 1-4 and columns A-D. The row south of the grid will be named row '5' and the row north of the grid will be named row '0'.
Within the puzzle, you access each room by way of a colored teleport pad. These colors appear to be random, but the location of each teleport pad in each room and its corresponding destination is fixed. Also bear in mind that each time you teleport to a new room, you are re-oriented to face West. So you may find it easier to follow this walkthough by turning to your right (to face North) each time you enter a new room. Each time you enter a room, you will un-light a square if it was already lit. In this case, jump to re-light it before moving on to the next room.
1: From Start, Go A-5, B-5, A-3, C-4, D-2, B-1
2: From B-1, Go C-3, D-1
3: From D-1, Go B-2, A-4, C-3
4: From C-3, Go A-2, C-1, D-3, B-4
5: From B-4, Go C-2, D-4
6: From D-4, Go B-3, A-1, C-2, B-0, A-0
Now the puzzle is complete and is safe for the rest of the party to travel through.
The following path gets you from the start to the end:
From B-5, Go A-3, C-2, B-0
This path gets you from the end to the chest:
From B-0, Go A-2, B-4, D-3
And finally, this path gets you from the chest back to the end:
From D-3, Go B-4, A-2, B-0
