Old Capital Metro Core Floor 1 Walkthrough

# Floor 1 Walkthrough
1
You will start the stage with a [Research] Overload Distribution Resonium that will heal your characters and increase their damage every time pressure reaches 100, which causes an overload and results in a Corruption.
2
The Masked Scholar will appear after getting the Resonium and offer you three A-Rank Resonium in exchange for three Corruptions. You will get value out of getting the Corruptions because of the Research Resonium you get earlier.
3a
After talking to the Masked Scholar, you will spawn at the top left part of the area, far away from the exit at the bottom left. It's best to clear all the tiles before heading to the exit to get all the buffs and increase the number of Corruptions.
3b
Increasing or maxing out the number of Corruptions will get you more help from the Masked Scholar on the next floor.
4
Head to the exit and defeat the Goblin and Notorious Thanatos to reach the next floor.

2
Collect all the rewards in the area after talking to the Masked Scholar. You should also get the rewards on the right if you cleared floor 1 with an S rating or grade. Head to the transmission above once you're done!
3a
You will spawn at the bottom middle, surrounded by two Double Crisis tiles and Vault tiles (Quarantine Gates). The exit will be on the opposite side, and you can get there quickly by going straight upward.
3b
You can choose to clear all other tiles in the area and start removing some of your Corruptions to make it a little easier when fighting enemies and the floor boss. Otherwise, continue building up Corruptions to get more value from your Resonium.

4
Defeat the Newborn Dead End Butcher at the exit to clear the stage and get all of its rewards!
