This is one of my longest project so far due to the lack of resources, many tests, and exploration of collectable items. The most important part is to streamline the guide and make it easy for players to use because after part 1 of the game, it kind of make players lost and confused, didn't know where to go. Some of the dungeons may need you to finish certain side quests to make it easier rather using traditional brute force like Final Fantasy game.

Move around using map: If you are using a mouse, you can select red pin, quest indicator, or chest and move there. If you are using a controller, in the menu, press "Square" button then you can select those move point. Leo will automatically move to that location. This is very handful when know where you want to go.
Growth Map: Is where you're unlocking stats characters using SP. The good part is can you release SP can to unlock other skills depending on the situation. For example, fighting a specific boss requires specific skills.

Most of the side quests are optional, however, they seem to be important to complete in this game because they often provide equipment/items for beating bosses, ultimate weapons, and even access to New Game+. So I highly recommend you don't skip them at all.

There are a total of 8 characters, most of them have primary and secondary elemental skills (they deal more damage using their primary elemental skills). Table below is just a snapshot of the overall characters. I have a dedicated page for their skill list here.

Unlike traditional Final Fantasy games where elemental dominance is a circle, for example, Fire -> Ice -> Lightning -> Fire. In this game, elements are weak and strong against each other. Fire damage is strong against Ice elemental monsters, at the same time, Ice damage is strong against Fire elemental monsters.

• Fire <--> Ice
• Lightning <--> Earth
• Holy <--> Dark

When using maps, I'll use the following annotations to make it easier to understand:
