You could always cast Provoke and he will automatically attack with Blast Punch, which only halves that characters current HP each time. This leaves Auron open for mental break and Lulu to take advantage of that double cast.
What Riverstone said, doing Lulu only so no Provoke or mental break for me :3
I tried Zanmato, he's immune :(
ah i see... im not familiar with these challenge abbreviations haha
