This needs to be thought out… Instead of half completed creates, we should be given a quest that says that the supply vendor needs such items to complete a create she is stocking… this way you can carry multiple scroll orders and search for those items.
Just to clarify, instead of a box or create it’s a scroll with a list of items the supply vendor needs. locate these items, turn them in for rewards etc.
BAM problem solved…
In order to make the items list more of a challenge, have items on the list that must be acquired by a mage, warlock, rogue, etc… Or allow the scrolls to be given to someone else who needs the quest
