Probably under leveled but you will have to learn how to not get hit more than once per opponent turn. That's why speed and parrying are key. You need to limit the times the enemy is on offense + you have to parry to win AP, do massive damage and if you have the right lumina, heal yourself.
Also, try playing around with your pictos/lumina. You'll start finding out formulas to either protect yourself better and give you more chances if you do get hit (instead of insta death or very depleted health) and/or ways to be on offense more than the enemy. As
@Renkz said, do some exploring in other areas and go pictos hunting, you'll find a ton of useful shyt out there.
