You have mastered the art of creating a certain kind of magic item.
Prerequisite: Any item creation feat.
Benefit: Each time you take this feat, choose one item creation feat you know. The XP cost for creating items with this feat is reduced by 25% (that is, 75% of the usual cost), and the purchase DC of the raw materials is equal to the items' purchase DC -3 instead of -2.
Special: You may take this feat multiple times, and its effects do not stack. Each time you take this feat, it applies to a new item creation feat.
