Weapon

Uncommon

This whip is made using the shrunken tentacle of a great sea creature. It still moves slightly on its own.
   As an action, you may try to wrap a medium or smaller creature within the weapon's range using the whip 's tentacle. The target must succeed a DC 14 Str saving throw or become constricted by the tentacle, dealing 1d4+2 bludgeoning damage immediately after failing the saving throw and agian on each of its subsequent turns while gripped by the tentacle. The creature may reattempt the saving throw as an action eact turn to escape the tentacle again. While holding a creature in this way, you cannot make attacks with this whip. You may end this affect at any time (no action required).
  While constricted, a creature cannot move or be more than 10 feet away from you in any direction, and your speed is halved. If you drop the whip while a creature is constricted, both you and the creature's  movent speed return to normal, although the tentacle will continue to hold until the creature breaks free.
