In Gabranth's normal mode all brave attacks (Sentence, Lunge, CoJ) have "Cancel Attack with Ex Charge" at the end of their description. So I tried doing this for all normal brave attacks, and it doesn't work for me. What exactly do you think they mean here? Did anyone have success performing it?
The way the description makes it sound like is that you should be able to execute a cancel at any point when executing the move. And I don't think it refers to the cooldown after Gabranth's brave moves as I can do any other brave attack right after or dodge.
