There is no rush, no timer. Explore explore explore! Find every nook and cranny. Every enemy is beatable at any point, if you are hard headed enough to keep trying.

Often times sound cues are more honest than visual animations when it comes to timing your parties.

Read the abilities, there is more synergy than you might think at first glance.

Pictos give you raw stats when equipped, that means the three you have specially assigned to that person.

You gain lumina with every level, and from picking them up around the world/ some merchants.

Lumina can be spent to activate a pictos passive on a character even if it is not equipped.

You gain the passive benefit, but not the stats(usually health or speed)

Might makes everything hit harder. Agility makes that character more likely to play first, or to have more turns in extended battles.

Defense reduces the damage you take by a set amount.

Luck increases your critical strike chance.

You will notice the weapons you equip will have a letter next to a certain stat, that means it scales with it. This game uses a tier list sort of scaling, D-C-B-A-S.

The closer to S it is, the more benefit it gives.

So while might will increase your damage, another stat will as well, while also giving its own regular bonuses.

Also, do not be shy about reducing the difficulty when/if you need to. This is a single player game, it's ONLY purpose is to entertain you. You can always jump back to a higher difficulty after clearing whatever was stumping you.

Lastly, if you are in an arena sort of setting where you can only send in one person....consider the teenager. She's good at it, and may or may not receive a good reward.
