Roland Delacroix said:A cleric with Craft Wonderous Items can get an arcane magic user to cast the arcane spell portion of the item's creation. I don't see why it would be hard to hire a wizard to cast a spell in such a large town.
This is what I thought when I took the feat, but I can't find anything that says that in the SRD, and the DM just points at the section of "Creating Wonderous Items" that says "If spells are involved in the prerequisites for making the item, the creator must have prepared the spells to be cast" and the section of the Feat description that says "The character can create any miscellaneous magic item whose prerequisites the character meets" and laughs.
As best as as I can tell, no cooperation is allowed on wonderous items.
