Never played Graces F before. Some tips for beginners?

Im loving it so far! I just finished thr childhood part.

I'm used to Vesperia/Abyss/Symphonia style of combat, so I'm struggling a little bit with the combat. It didn't click yet to me, so I wonder if someone can help me a little with it? Also tips about mixing and dualizing?

I managed to beat the boss at the burned village after dying like 4 times. Playing on hard btw!
