I remember there being rules somewhere for creating a construct then placing your soul into the construct. This wasn't a piecemeal deal or prosthetic, this was a full swap over. One of the things it talked about was the fact you could basically store yourself for a long period of time until someone woke you up. Does anyone know what i'm talking about?
The phylactery? Yeah, but the rules are NOT very specific.
It was a specific set of rules, a sort of immortality out that didn't require any outside assistance or "evil" lich ritual. It was a separate ritual with it's own rules but was lich-like in that you become immortal (unless your construct is destroyed, then you could be resd at the age you were when you underwent the ritual) and no, it wasn't possess object. thanks for that though... might let us homebrew it...
Are you talking about those Terminator 2-like creatures (who's names I can't remember) from the Shattered Star AP? They were servants of the Runelords transformed by a ritual into living starmetal.
Clockwork Automatons! That's what they were called. They were in an odd little side text of some kind.
