Currently looking for a clearer citation as the provided link was during active Enkidu development time while the wordings were still being ironed out and the wording there suggests that the core power is expended at the end of the scene if Bifurcate goes off, rather than the presented "when Bifurcate is successful."

I will get around to adding this once I manage to find something though, so I'm leaving the issue open until then.
