IF you stand close and read the pipe text it tells you which order to "use" the pipes in
Although a bit vague and hard to understand...

As you look at the 4 pipes
think of them as 1 -2-3-4 left to right
Use 3--places the hand in it
Use 1--places the ring in it
Use 2--places the staff in it
Use 4-places the blood in it

3-1-2-4
Then you complete the quest [img]smile.gif[/img]

Hope that helps and was what you wanted
