Greater Counterport (Su)

At 10th level, a Riftwarden can counter a teleportation effect as an immediate action, without the need to ready an action beforehand. In addition, as a full-round action, the Riftwarden can expend two uses of her planar channel ability to forcibly recall a creature that used teleportation to exit an area within 30 feet of the Riftwarden since the end of the Riftwarden’s last turn. Planar channel deals damage equal to the amount normally dealt by one use of planar channel. This damage affects only that target, and affects it regardless of its current distance from the Riftwarden. If the target fails its save, the teleportation effect is reversed and the creature returns to the point from which it teleported (or the nearest available space, if that space is now occupied by another creature).
