Soul Stone

A Soul Stone is a dull pearl that can be used to store souls. Once active, it will glow with a color and intensity relating to the nature and power of the soul it contains. When a dying creature holds a soul stone, they can choose to transfer their soul inside of it. The soul is preserved inside the stone and it can then either be resurrected or used as a magical ingredient at some later time.
== Variants ==
=== Shackled ===
A Shackled Soul Stone is one that is covered in chains, and it does not allow the creature to choose whether or not they wish for their soul to be transferred into it. This variant is particularly useful in capturing and binding elementals, angels, and demons as these are beings of pure soul.
=== Cursed ===
The cursed variant of a Soul Stone will rip the soul out of any who touch it. Additionally, souls it stores will be destroyed after being trapped for three days.
