I wanted o get a community opinion about capturing the souls of unded. Create Soul Gem needs to be used on a recently dead creature, but an undead creature (for the purposes of argument an intelligent undead) has essentially been dead for as long as it's been animate. When it hits 0 hp it's destroyed, not dead. There's no dying, nothing. Create Soul Gem specifically targets dead or dying creatures.
My ruling, no creating Soul Gems. Trap the soul, while they're animate, sure.
What do you think?
What happens to undead souls in Golorion?
Bit of a tough one since some undead effectively are only souls (ghosts). But some are just bones/flesh animated by necromantic energies hence no souls. So I would go on a case by case ruling on this one.
