I can't beat the Bellum controlled Linebeck. My brother and I can't get the fairy back from bellum's arms. The guides I used said slash at him untill it says rub and then the fairy is free, I forget fairy's name.
First off-Spoiler warning. Put it in the title, please. I've already beaten the game, but that doesn't mean everyone has.
Second off-
Just keep fighting, you'll eventually have your blades crossed, and you'll just keep rubbing until Ciela's free.
Once you've clashed swords with Bellum and out rub him (hmm, that'll probably sound weird), you should be given a chance to strike him. Once you hit him, Ciela will be able to release a Phantom Sphere.
Thanks for the advice now I can't beat without dying 3rd time. ;)
