Resonium Merchant's Management Insights

Unlock after completing the following investigation mission:
In "Lost Void: Battlefront Purge", inflict the Impaired status 3 times while battling Geppetto.

Running a Resonium business in the "Lost Void" requires attention to many things.
Keep a close eye on customer demands, collect more popular supplies; watch the quantity of goods you carry to avoid being identified by the "Puppeteer" as a potential combat unit; try to complete transactions quickly, or customers might suddenly turn into "Puppets" while haggling...

Here's another tip:
If you can find "that one" route through the abandoned bunker area and Ether extraction towers, you'll get a group of big-spending, regular customers.


Blue Ocean Market for the Brave

Unlocked after completing the following investigation mission:
In "Lost Void: Battlefront Purge", defeat 5 enemies summoned by Geppetto within 3 seconds after hitting them with an "Assist Follow-Up".

After New Eridu was established, Ether Energy Module research gained popularity, while studies on Hollow Operations gradually faded from public view.
Even after research funding was unfortunately cut, some still insisted that those who truly "understood" Ether were the ones who could wield it to eliminate Ethereals. Some "militant" researchers began to sustain themselves through the Hollows.

Funding would always come through; after all, if you want to sell clean water at premium prices, the best market is a desert—
And here lies a "desert" that forces people to walk right into the trap, time and time again.


A "Parent's" Duty

Unlocked after completing the following investigation missions:
During the battle with Geppetto in "Lost Void: Battlefront Purge", inflict the Impaired status on its tail.

An Exploreboo who calls itself the "Great Explorer" is a most popular friend in the Lost Void; the Navigation Data it has collected through years of adventures serves as precious supplies in this chaotic area.
The Great Explorer is never stingy with help! However, when fellow Bangboo receive Navigation Data from it, they often have to accept its earnest yet strict instructions, mainly about how "Bangboo guardians have a duty to protect fragile humans from falling into danger"...

It's said to be a "failed guardian" tirelessly wandering, searching for its lost human.


Regular Show at the Puppet Kingdom

Unlocked after completing the following investigation mission:
During the battle with Geppetto in "Lost Void: Battlefront Purge", when it uses "Shadowy Epilogue", ensure your active character is not hit or inflicted with the Suspended status.

While Ethereals in other Hollows or areas might choose to be idle wanderers roaming aimlessly all day, the Ethereals in the Lost Void have their own responsibilities.
Patrolling the edge of their territories, ambushing intruders, exploring Mist Areas... Though they are senseless and unaware, and don't understand the purpose behind their actions, they still carry out their duties faithfully under Geppetto's guidance.

Geppetto declines to be interviewed by investigators on this issue — after all, it's just as clueless.
