Zaydos's Improvised Brewing (Item Creation)
Although known much more for his potions, the brewing principals of Zaydos can be applied to nearly anything.
Prerequisites: Any Item Creation feat
Benefit: You can craft magic items which you do not have the appropriate Item Creation feat or prerequisite spells for. You must still meet the minimum caster level for the item, and all other aspects of item creation remain the same. If you do so, the items remains functional for only one week after creation, minus one day for each prerequisite you do not meet.
