Hi all,
Long-time lurker and first-time poster. I have been reading many of the past (very useful) posts, and I am wondering how everyone is handling incorporeal entities such as ghosts, spirits, unmanifested demons, etc... I am planning a modern paranormal investigation setting (highly influenced by the fantastic Esoterrorists RPG). It will be a low, secret magic setting where supernatural effects are more subtle and may not be immediately obvious (Illusion and mind control rather than fireballs and telekinesis). I can't seem to find any information in the core book or posts about purely non-physical entities. My idea was that they could not be affected by physical means (with the exception of certain mystical items possibly), and the investigators would be forced to use rituals and/or magical lore to confront and defeat them. My combat-monster PCs would be ineffective in this case and forced to rely on the bookish occult scholar (don't worry; still plenty of thugs and cultists to physically thrash).
I can see using removing physical characteristics entirely, and using Strain instead of Wounds, but it seems incomplete. Would they get a Soak based on Willpower? Should there be a non-physical analogue to Wounds (Power or Energy maybe)? I would appreciate feedback on this, and I am curious if anyone else is doing something similar.
