I have 3 of the 5 elements. I found the one in the tower,one from Abrideen, and the one from Lysandra but cant seem to get other two. I cabt figure out in what order to pull the switches in the treasury vault nor can figure out how to get into the room in the armory with the broken switch. I believe the other two I need are in there but with no avail cannot figure it out. Any help is much appreciated. Thanx alot

Greetings!
Shoot an arrow at the skeleton behind the gate with the broken gargoyle yank. The skeleton in dying will pull a yank on the other side and open the gate.
In the treasury area keep pulling the yanks until all of them go down and stay down. The last yank you need to pull is the one (as you face the treasury gate) on the left "aisle"

X * * = yanks X - last yank
