Simple RAW for Pathfinder Thread V: Golarion Strikes Back

[Calthropstu]

A228:
For the more expensive spell, use the formula as normal. For the second, and future, abilities multiply the cost of adding it by 1.5.
I don't see any way, RAW, to link the two abilities. As previously mentioned, you would have to quicken one to get them both off in the same round.

You might be able to argue a cost reduction since you would be adding a target restriction on the animate object of "the fabricated object" and if you add a restriction of a particular type of object to be created, it could be reduced further. But that is up to GM adjudication.
