wrote:Certain requirements must be met in order for a character to create a magic item. These include feats, spells, and miscellaneous requirements such as race or kind. The prerequisites for creation of an item are given immediately following the item's caster level.
A spell prerequisite may be provided by a character who has prepared the spell (or who knows the spell, in the case of a sorcerer or bard), or through the use of spell completion or spell trigger magic items or a spell-like ability that produces the desired spell effect. For each day that passes in the creation process, the creator must expend one spell completion item or charge from a spell trigger item if either of those items is used to supply a prerequisite.
It is possible for more than one character to cooperate in the creation of an item, with each participant providing one or more of the prerequisites. In some cases, it may even be necessary.
If two or more characters cooperate to create an item, they must agree among themselves who will be considered the creator for the purpose of determinations where the creator's level must be known. The character designated as the creator pays the XP required to make the item.
Emphasis mine. Item Creation feats are a prerequisite of item creation, and thus may be shared out to any of the participants - not necessarily the "primary creator". And by the way - the creator's level is almost never called for on anything (although
caster level frequently is - but that is a class feature which as per those rules is free to be shared out to any of the participants).
There is absolutely nothing in there that would lead us to believe that it is not legal for the Elven Wizard to "assist" the fighter in making a Cloak of Elvenkind - by providing the caster level, the elven blood, and the Craft Wondrous Item feat while the "primary creator" (the party fighter) slaves away and produces this mighty item by spending the time, money, and of coure - XP.
