The floating jellyfish easily avoids the poorly swung attack by Natacia which provides it an opening to finally wrap its tentacles on her.  It entangles her arms in a way that prevents her from using her two-handed sword while a few of the tendrils wrap around her legs preventing her from moving.<br/><br/><hr/><br/>Natacia can't move and suffers -4 to Dex.  You make an attack or action that does not require two hands but suffer -2 to hit and combat maneuver checks (CMB and CMD).
