The actual task itself is a five minute job, however getting to "throne/platform" in the North Room is a full on mission in itself. With IVU and a bit of luck avoiding the many wandering Bokons, you can run up the center of the room to the back of the platform which is safe plus there is a hidden passage behind the platform also mob free.
One other thing to note is the High Bokon on the platform which needs to be cleared is a PH for named High Priestess Kal`vius, who kindly spawned on me when just after the three Bokon Conduits popped.
I lost count of the number of times my ranger died trying to separate the Conduits from the named but I finally succeeded and got the caster shield, which I couldn't use, for my trouble...
