Cord Shelter

Protect nearby spirits with a luminous web of silver cords. For the duration, creatures of your choice in the emanation cannot be possessed, magically put to sleep, or have their souls displaced. They also have advantage on saving throws against charm, banishment, and unwilling teleportation.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
