Dread Invitation

One creature that can see or hear you makes a WIS save. On a failure, it cannot willingly move farther from you until the end of its next turn. If it is already charmed by you, it instead uses its reaction, if available, to move up to half its speed toward you.

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