Looking for input on how to properly read this.

Dark craft gold pieces and dark craft experience points can’t be used to buy goods or attain higher levels, but they can be used instead of actual gold pieces or experience points when making a magic item. Only a single application of dark craft experience points and dark craft gold pieces can be applied toward a magic item’s creation process.
The time spent creating the item does not change when the celebrant uses dark craft resources. When the celebrant completes a magic item created by the use of any dark craft resources (as little as 1 gp or 1 XP), the item is tainted with evil. Others can sense this evil, as described for an object of lasting evil (see Lingering Effects of Evil, later in this chapter). Dark craft experience points and dark craft gold pieces can be combined with the destruction of souls to make a magic item even easier to build (see Souls as Power, later in this chapter).
The point of contention is bold above, question being what "a single application" is in reference to.

Option A: Both Dark Craft GP and Dark Craft EXP can be applied, but they can respectively only be sourced from a single sacrifice.

In this scenario, a single magic item can at most benefit from 2 sacrifices, one made for Dark GP and one for Dark Exp. This requires you to keep track of all Dark Craft resources in separate batches, with minimum DCs respectively netting of 45 Exp and 100 gp. If less than the total of a batch is spent (e.g. 30 Exp for a basic 750 gp wand), then the remaining dark craft resource remains until either used for something that it covers (e.g. 15 exp for 0 level wand) or is combined with regular crafting resources (e.g. 15 exp to supplement another 30 exp expenditure).

Option B: You have to choose between applying either Dark Craft Gp or Dark Craft Exp.

Under this reading, you can not create a whole magic item using only dark craft resources (e.g. whole 0-2 nd level scrolls with just sacrifices), but you can stack up rewards from multiple sacrifices over time to cover either the whole Exp or GP cost as needed. This only requires one to keep one tally of dark craft gp and exp.


Option C: Only one character cooperating in the crafting of a magic item can elect to provide a single Dark Craft resource to the process.

This interpretation can be combined with either A or B if desired, simply adding the stipulation that only one of the cooperating crafters can provide (part) of their contribution with dark craft resources.

So thoughts anyone?
