You conjure a writhing tether of shadow between yourself and your target — a clearly visible bond of dark energy. If, on your turn, the target is still within range, the bond tightens and lashes their soul, dealing damage. While the connection remains, the target suffers a penalty to any attacks, unnerved by the oppressive force of the hex.
This spell countst as a curse.
Target suffers -5 to all attack rolls.
If the target moves out of range, the hex is broken.
