"Yeah, sure then."

"Uh, we're kind of on cooldown right now; we'd get any magic from me drinking Cam's blood but not the full effect - can you do anything about that; special-case us or something?  That'd be really really helpful in general."

'Somewhat.  I cannot eliminate it entirely.'

"That's fair.  And, oh - probably we can just ask you about conjured blood instead of trying it; does conjured blood work."

'That depends upon some specifics.'

"What specifics?"

Consider consider.

'Conjuring blood directly in Judy's stomach would create no magic.  Judy drinking from a basement-dweller corresponding to no existing person would create no magic.  Judy drinking from a basement-dweller of yourself would create magic for the both of you.'

"Conjuring blood in a cup?"

'Would create magic for Judy.'

"What about . . . a popsicle.  Of blood.  But like in a pretty design."

'If it were Cam's blood, that would create magic for the both of you.'

"...really pretty cup? Decorative blood fountain?"

'The visual design of the method of conveyance has no direct bearing on whether the blood's source receives magic.  The fountain would create magic for the source only via the blood which was created in the air, before the first time it had its weight supported by the fountain.  After that, only the drinker could receive magic from it.'

"...then why does the popsicle work?"

'Which aspect is causing confusion.'

"If the popsicle didn't work then I'd imagine that in order for me to get magic the blood has to be consumed from me or a sufficiently me-like vessel such as a basement dweller, but I don't know what principle covers popsicles and not cups."

'The popsicle, from my understanding of the concept, is a substance frozen around a solid core rather than being supported by a solid object it is enveloped within.'  Thoughtful wingflap.  'Placing a popsicle within a cup means that thereafter its source would not receive magic.  And I do not believe one could conventionally make a relevantly-functional popsicle; only through conjuration is this a practical consideration.'

"You could do it in zero gravity?"

'Possibly.'

"Okay. What if the cup was made of... my bone?"

'Only Judy would receive magic.'

"Why is the bone not okay but the basement dweller is?"

'A basement dweller is not a cup.'

"Why the fixation on cups?  Are they aesthetically super important?"

'Not especially.  When I devised the magic system, I - programmed - rules about cups specifically.  For cases which less clearly involve that binary, the rulings seem to have been extrapolated from my aesthetics at the time.'
