If I invoke a spirit into a physical vessel, and the vessel got damaged badly, do I get another vessel and do the invocations all over again or something else?
Really depends on how you did it.
If you can’t repair the vessel, you gotta unbind the spirit and destroy the vessel before you can re-bind the spirit in another vessel, assuming the spirit will let you re-bind it into a new vessel.
It wasn’t forceful binding, but frequent invocations of the spirit, asking it to enter the image. Not sure how I would do the ‘unbinding’ if my vessel got damaged beyond repair…
