The first item I will aid you in creating is a robe. You will gather the items for me, and we will put them together. Afterwards, assuming you succeed, you will have the first of many items that will make you more powerful and aid you in your struggles.
To start, you must have crafted Robes of Arcana. A tailor can make this for you, or perhaps you can purchase one from someone else--I'd be most impressed if you could make it yourself--but regardless, bring me the robes, and we shall go from there.
If you are currently using this item when you attempt to complete the quest, she will take the robes right off your back. It will be a while until you can get the completed robes so bring some backup clothing.
