Once you have all items head to Irda Isle Caverns, once inside head north to first west, then west to first locked south. Hold and use the staff to unlock the door.
Note: Each upgrade increases the archon level required to be worn by 10.
You may also have to hand her a regular fetish to start the upgrading procedure, she will then hand you it back and ask if she can artiface it, she will also still ask for a round thingy but just handing over the upgraded fetish works.
You can not artifice it higher than this. ''give fet art You give a faerie's fetish to an imprisoned artificer.
