The Blood Money spell has caused a lot of RAW & balance controversies over the years. This prior RPG Stack Exchange thread was extremely useful for me in explaining the Casting Time criteria that a given companion spell would need in order to be paired up with Blood Money. And I agree completely with Hey I Can Chan's assessment of James Jacobs' 1st ruling (linked above) being the ruling that should be in use.
Alas ... in some further reading of other Blood Money rules-threads on other forums, it seems some folks have some disagreement over which spells can be paired with Blood Money based on this specific text of the spell:
Material components created by blood money transform back into blood at the end of the round if they have not been used as a material component.
I come to all of you acknowledging that Blood Money (a Swift Action casting-timed spell) is ideally meant to be paired up with a spell that has a Standard Action casting-time, like Stoneskin. But some people seem to think that a spell with a casting-time of 1 Round, like Gilded Whispers, still falls into the category of being legal to use with Blood Money.
So I'm looking for clarification on what specific casting-time criteria is legal for a given spell to be effectively paired with Blood Money.
