Soul charge

Soul Charge was a necromancy spell contained in the Obsul Ssussun.

Description
As the name suggested, the spell charged a gem with a portion of the soul, stolen from a subject, for an entire day. Due to the long preparation time, the spell was almost useless to be used in the midst of combat.

The gem or the charged content could then be used to substitute the depletion of energy from magic items with limited use but it had some limitations.

Components
Soul Charge used verbal and somatic components but also required a focus.
