If the automaton familiar of an Illusionist sustains enough damage that it is reduced to 0 hit points, the spirit within it is considered “dead” and the illusionist must journey again to the Methetherial to bind another. As a safeguard against this event, however, the illusionist can protect the spirit by attuning it to a keepsoul phial.
A keepsoul phial is a magically crafted container approximately three inches long, usually made of glass or metal and sealed with a stopper of unalloyed silver. The phial can be embedded somewhere within the automaton’s vessel itself. If the automaton is then destroyed, its spirit passes into the keepsoul phial, where it lies inert until the Illusionist embeds it inside another suitable –and undamaged –vessel.
The phial can also be used to transfer the automaton familiar’s spirit to a new vessel, even if the old vessel has not been destroyed. The process of transferring an automaton familiar’s spirit takes 1d4 hours and can be done during a long rest.
