Following the tutorial, just spam the auto-battle to end the fight.
When the battle starts again, use the same strategy. Use a potion if your health gets low.
After the battle, go through the camera tutorial and save your game. Then proceed to the enemies up ahead. Take this time to get used to the battle system.
Open your map. See the yellow circle with the exclamation point? This is an event marker. We'll be referring to them throughout this guide.
March down the path towards the event marker. Use the blue circle to hop from level to level. Keep an eye out for these circles throughout the game- they often lead to hidden treasure.
Down the path, take on two more PSICOM????, followed by another PSICOM???? and two PSICOM???.
Once you take care of those guys, go further down the same path and grab the potion from the treasure chest.
A bit farther along, grab another chest with two more potions from the platform to the right of the path.
You'll encounter a ?????? with some PSICOM???? along the way. Keep attacking and heal when needed.
Continue on and grab the Iron Bangle from the chest on the platform to the left.
Navigate through the crates and descend down the stairs. There's 50 Gil in the treasure chest hidden between the crates to the right.
You'll have one more easy battle before you encounter the a group of enemies and the item tutorial.
Watch the cutscene and head up the stairs to the save point.
Save your game and hop down to the switch.
Activate the switch.
Head towards the the enemies ahead, and go through the chain/stagger tutorial.
When the real battle starts, take out the small guys before you concentrate on staggering the more dangerous enemies.
Watch the cutscene. You'll start the next section as Snow.
