ring. wedding ring. go back to the hallway that turns north off the regular path. it took you to a room with myconids and such like in it to kill.
to the left of that entry way, looking north are two skellies on the wall. click them. you get that round double arrow, clicked once and you get a little story, clicked twice and you get the ring.

have ring, hand, staff and blood in your pack. any order. now for the pipes.
from left to right they are numbered 1,2,3,4.... so you should click them in this order: 3, 1,2,4. each one will kinda explode. at the end, a puff of smoke in the water will show a sword and when it disappears, you have Lilarcor in your backpack.
*smiles* enjoy.
