Dusk Diver 2

Story-related and cannot be missed.

This trophy is for completing Chapter 2, "Overture". This Chapter continues your introductions to new characters, mechanics, and more. It will also take you to two new locations: Climax 508 and the World Trade Center (Youshanding). You'll get the trophy after a brief cutscene when you return to the shop, after your victory against this Chapter's final boss.

You'll start off the Chapter with a mandatory side quest, as part of your introduction to them. You should be checking the map every time you return from a quest to see if new side quests have spawned. (See Youshanding's Jack of All Trades  for a complete list of side quests & when they unlock.)

Another important thing you'll be introduced to are the Possessed. These are ordinary citizens who have been possessed by Chaos Beasts. While they will be marked on your map to start, that is only the case for this Chapter. That said, you'll find them pretty much everywhere, and they're quite easy to spot. (See The Evil Within  for more info.)

[SPOILER WARNING!]

This Chapter also contains your first real boss fight. After you head out to Climax 508 to meet up with your old friend, Le Viada, Bette randomly attacks her, and all of you are quickly pulled into the World Trade Center (Youshanding). Here, you'll have to make your way through the level until you catch up with the duo.

BOSS FIGHT: DELIRIOUS BETTE
Although you might be tempted to try using Le Viada against her for ranged damage, Viada is not strong enough at this point to really do much, and Bette can be quite painful. Use your Burst when you can to stun-lock her with constant attacks and build up towards your Burst Ultimate. Otherwise, the only real tips are the normal, obvious ones: try to get Just Dodges and counterattacks where you can, and most of all, avoid her bats! They can end up stun-locking you by constantly knocking you back and throwing you in the air.

This fight is also the first time you'll learn that enemies have Bursts, too! Once they get to around 1/3rd health, Bette will use her burst, which increases her armor twofold.

Once you finally get her health down far enough, you'll learn about your own Burst EX, which increases your max Burst Gauge to 200%. (See Transformation Sequence  and Show Me Your Moves!  to learn more about Bursts, Burst EX, and Burst Ultimates.)
