Dealing more damage
Attacking the enemies from behind deals more damage than from up front. Use that angle of attack whenever possible.
You can do a joint attack on enemies whenever your character's body is burning with fire. You get this burning effect when you receive a certain amount of damage. When using that character to attack, a nearby ally will team up with you.
If you want to aim better without moving from your current position, when controlling your character, hold R1 during a battle. An arc will appear. The highlighted arc shows the range where you can attack. Aim at the enemy and attack.
Golem Mask and Stuffed Bear
When fighting Bebedora and her two Altimas, remember to either kill the Altimas or steal from them to make sure you get Bebedora's Stuffed Bear and Maru's Golem Mask.
