SW5e : Clone Wars

You project the spirit bound in your mask into a nearby corpse or homunculus for up to one hour. The possessed body speaks with the Echo Spirit’s voice and moves with his knowledge. During possession, your homunculus’s eyes glow with burning script, becoming capable of basic spellwork. At higher skill, the Echo can use Force Drain, basic alchemy, or one short-range illusion per projection. The voice of the Echo remains in your mind afterward, becoming more defined and manipulative, while your mask may gradually reshape to reflect its original form.
