The Elder Scrolls: Tamriel

You bind a creature's soul to a vessel upon its death. When you cast this spell on a creature within range, if that creature dies within the next minute, its soul is trapped in a vessel of your choice (such as a gem). The soul remains in the vessel until released or consumed for magical purposes. This spell has no effect on creatures that are not living or do not have souls (such as constructs or undead).
