“With a shriek, the horror disappeared. I knew it was not gone. ”   You curse a hostile creature to be the singular focus of your hunt. You always know where the creature is, and it can never be hidden from you. In addition, you can sense what areas are in the target's line of sight. On a subsequent turn, you can use your bonus action to teleport to location within 30 feet of the target as long as the location isn't in the target's line of sight. If the location is occupied or is in a solid material, such as a wall, the teleportation fails. It also fails if you and the creature aren't on the same plane.
