Fight Everything
There are a lot of enemies roaming the lands as you explore the world of Final Fantasy XV. Surprise battles don’t work in the same way they did in most main Final Fantasy games, allowing you to see what you’re getting into and then granting you the opportunity to get the heck out of there. However, if you want to level up quickly and earn a lot of AP, you’re going to want to get into fights as often as you can.
You should be capable of handling the monsters in every new area you find yourself in as the story progresses. Take advantage of that and fight them all. Also, don’t be afraid if an enemy is a few levels higher than you. Due to the fact that Final Fantasy XV is an ARPG, your skills will determine who wins fights that you’re under-leveled for. If you’re feeling confident in your dodging abilities, go for it.
