In other news; IT can't really manifest from her astral form like you mention in the IC thread. She'll just return to the trunk of the car.
@Siren - I think you may be confusing between manifest - letting a mundane person see you when on the astral - still being in the astral and cannot effect the regular world. (good for communication and stuff). I think that mages can talk to mundanes by manifesting when they project. This creates a ghost like semi transparent representation of the mage that people can see.
Yet, they cannot cast spells or do anything that effect the meat world. I don't mind if you cannot do it- I mean there are many versions to this game. I just point that up because I think there was a confusion between the two.
Manifest I think that both mages and spirits can do.
The other power is materialize - that gives you an actual body in the meat world that only spirits can do.
About the specific - since there are so many versions of this game that I am okay either way...the talk to Flea could have also been done few seconds later with the matrix.
Since manifesting is really cool to do... I find it in the rule book:
core rules p 314:
Manifesting
A purely astral form such as a spirit or an astrally projecting
magician can interact with the physical plane
by manifesting. Manifesting is a psychic effect that lets
you make yourself visible and audible on the physical
plane through an act of will. Manifesting takes a Complex
Action to engage or disengage. You appear on the
physical plane as a ghostly, hazy image of your astral
form and may freely communicate with physical characters.
Unlike the Materialization power of spirits (p. 314),
manifesting doesn’t give you a physical form, so you
can’t interact with anything physically (or be harmed by
physical attacks). It’s a psychic connection, so you can’t
cast spells on targets on the physical plane while you’re
manifesting. For the same reason, technological devices
can’t detect or record you. You’re still on the astral plane,
so astral attacks can still target you. Manifesting is pretty
taxing, so you can only manifest for a total of your Magic
Rating x 5 minutes per astral projection session.
