Tales of Xillia
The Fezebel Marsh section was really amazing, the chain battle netted me tons of exp/gald and then the fight against three previous bosses at once. Then I got curbstomped by Gaius, it's possible to win that fight but it's made to be tougher and you're allowed to lose. I made him lose half his health before he used his Mystic Arte and just ended the fight.
Muzet showed up, the angel/spirit chick from the opening movie. She's an arte you can perform that has four element types of damage and is quick, it just eats TP. I'd love to say that she's great but I swear they make it too obvious when a character isn't actually on your side, there have been at least three small instances where you can tell something is off. Well I guess she might be on our side, for now at least.
Oh and I can use Mystic Artes now too. They're neat, not much use in random battles because it empties the link bar but good for boss battles.
