I have only really fought Titan (Hard) twice, and haven't fought Titan (Story) in quite a while. As for Titan (Extreme) I still haven't unlocked it yet. So you will excuse me if I haven't yet mastered what the names of all of his attacks happen to be. I still say Blood for Blood is a bit risky. That said, I will not deny that the extra 10% damage is a nice addition to have on occasion. That said, I am not entirely sold on wasting my time trying to get Mantra. I think I would rather use Feint in that Cross-Class Slot all told.
