Bellum has three phases to his battle. First, Link has to fight him in is "visual" form. Bellum starts out in a pool of purple ooze. From there, he shoots little purple splotches that can hurt Link when he is hit by them. But, if he doesn't hit them, they turn into ooze monsters. In his second phase, Bellum takes over the Ghost Ship and must be fought while controlling Linebeck's ship and targeting Bellum's eyes that appears on the ship. During the third phase, Bellum takes over Linebeck's body and must be fought in a sword battle. Bellum captured Ciela with one of its tentacles and Link must attack Bellum enought to destabilise him and allow Ciela to give him a sphere allowing Link to stop time and attack Bellum's eye.
