Soul Jar

From Into the Wilds Wiki

Soul Jars are magical items which act as a vessel for a soul. The jar may be activated by removing a stopper, cap or by using magic to trigger its ability. Typically the creature targeted by the jars abilities must demonstrate strong will to resist the pull of the jar, or their soul will be sucked from the body and trapped in the vessel. The body is left behind.
Opening the jar filled with a soul usually releases the soul within.
