I consistently get this message when my necromancer tries to raise a slave from a corpse. The message's effect seems to be that the slave always starts at 1 HP. From some experimentation, it further seems that the source of this message is the fact that the corpse I'm trying to raise is cooked.
Can anyone confirm this? Are there any other consequences to this message aside from the slave starting at 1 HP (and therefor being afraid)?
