Thaumatech Factory (Second Visit)
Teleport to "Thaumatech Factory -> Rooftop" in Machine Realm you'll be on the rooftop.

- (I-01) Heal Stone: you should immediately see one chest behind the wall. Pick it up.
- The other side has 2 Machine Chests which you cannot open right now. Go east and use the elevator (A) to go down.

- Move to the red pin at the bottom (B).
- Move the red pin at the far left (C). But before you go any further, let's save the game.
- In the next section, you'll see 2 more Machine Chests, so ignore them for now and approach the center for a boss fight.
Preparation
Equip your strongest weapons and armors on Leo and Zinikr. Equip Small Jade on Ez, it helps HP a little bit sine his skills don't require MP.
You fought this boss before twice already, but this time is different. When the battle initiated, use either "Analyze" for "Research Lens" for intel then keep hitting the boss. However, there are repair drones keep healing the boss for 99,999HP. After 2 turns, a mysterious guy helps you destroy those drones so that you can start dealing damage.
Strategy:
- Pretty standard fight. The boss is weak against "Lightning" so Leo's "Ltng Slash" deal a good amount of damage.
- Watch out for "Elemental Resist Down Missiles", this skill makes you weak to a specific elemental attack (for example: red which is fire). After it uses this skill, it will open up its 2 arms showing different colors (for example: red and blue). So you should always destroy one arm that you are weak against. From the example, you should destroy red.
When the battle is over, exit through east entrance (D).
There is nothing here. Just keep following the path until you get a vision from the mysterious guy again.
- (I-02) Ether L x3: When you appear, take the elevator to your left.
- Hop back on the elevator, then follow the main path and take the second elevator.
- Walk east a little bit you'll see the entrance to "Secret Base". Enter the base.
Secret Base
- Enter the Secret Base Hall (G) , then go upstairs to "Royal Quarters".
- After a lengthy conversation with Prickle and Clicker, go talk to them again they'll give you back the locket. Then exit the room.
- (Optional): If you enter the "Guest Room", you'll trigger a very small scene.

- Go out to the Secret Base area, there are 2 machines on the left (a), one is selling items and the other one selling gemstones.
- IMPORTANT: this step is important. (b) To the east is the door where Cheryl walked through. Go there to trigger a small cutscene where Zinikr suggest the team to explore the world for a better chance to survive for the upcoming battle and you should.

Do not go any further, it's time to go back and upgrade stronger weapons. Also, I suggest you to stock some items for Ez at the converter machine (a).
