Content Details
- Enter the Refraction Railway menu to select between <Refraction Railway Line 1 BokGak> or <Refraction Railway Line 5>.
- <Refraction Railway Line 1 BokGak> unlocks upon clearing Main Story Stage 8-33, and can be accessed via the Drive tab.
- The Line can be accessed anytime without spending any resources.
- You can spend a certain number of Modules (only for the first time) at the Lost & Found to claim your Refraction Railway rewards.
- Upon entry, make a Team by Deploying your loadout of Identities and E.G.O. Unlike in previous Refraction Railways, even if you are in the middle of this Refraction Railway run, any changes (such as Level changes, Upties, or Threadspinning) made to currently Deployed units will be reflected in your current run as well.
- The Refraction Railway presents a very difficult series of battles; we strongly recommend that you enter the Railway after meeting the recommended Level & Tier conditions.
<Major Changes>
- The Refraction Railway Line 1 BokGak will have a new Recommended Upgrade Level: Uptie Tier 4 and Level 55 for Identities and Threadspinning Tier 4 for E.G.O.
- Identity Level in Refraction Railway Line 1 BokGak will be capped at Level 55.
- Refraction Railway Line 1 BokGak enemy stats and Skills will be adjusted to reflect this change.
About Line 1 BokGak
- Line 1 BokGak comprises 13 Stations, each of which features highly difficult challenges.
- "Clear Turns", which is the number of turns it took for you to clear the Station, and "Total Turns", which is the cumulative number of turns it took for you from the first Station to the current Station, will be displayed above each Station.
- Any remaining E.G.O Resource after the Station can be used in the subsequent Station.
- Please check the bottom of the screen to view your Deployed Identities' HP and SP statuses.
<Major Changes>
- Once a Station is cleared, Sinners will now recover HP, and dead Sinners will be revived.
- SP values will carry over from one Station to another; revived Sinners will retain their pre-death SP values as well.
<Loadouts>
- Refraction Railway Line 1 BokGak uses the "Chain Battle" system. In Chain Battles, when a Deployed unit is defeated, the Backup Units will fill their spot according to the Deployment order.
- Backup Units receive Starting SP buffs, and Backup Units further back in the Deployment order receive greater Starting SP buffs. Minus Coin Identities receive negative Starting SP buffs.
- Please note that Lobotomy E.G.O::ln the Name of Love and Hate Don Quixote and Lobotomy E.G.O::The Sword Sharpened with Tears Rodion will receive positive Starting SP buffs.
<Major Changes>
- In Line 1 BokGak, you can enter the Station only when you have selected both your Deployment and Backup units: 5 and 7 units, respectively.
- You can change your Team Loadout between every Station—change your Team's Identities, E.G.O, or Deployment orders as you see fit.
Focused Encounters
- Only up to 5 Identities can be fielded at once in each Encounter.
- Every battle in the Refraction Railway will allow you to directly match ally skills against enemy skills, just like in Focused Encounters.
<Buffs>
- A defeated ally Identity will give E.G.O resources that correspond with the Sin Affinities and the Rank of each Attack Skill on the defeated Ally.
Combat Progression
- You may choose to retry or give up on a stage.
- Selecting either of those options will reset the Stage, and will put you back at the beginning of the first wave should you attempt it again.
<Defeat>
- If all of your allies are defeated, you can choose between returning to the Team Loadout menu to change your Deployment orders or immediately retrying the battle from wave 1.
- Giving up brings you to the state immediately before entering the said Station.
- Retrying the Stage retains your Deployment Order from when you first entered the Station, and will return you to the start of the first wave.
- You may restart from a previously cleared Station.
- Restarting from a previously cleared Station will revert the state of your Identities' statuses and your E.G.O resource reserves to that point as well, and delete any Stage Clear records made since entering that Station.
- Reaching 100 Turns in a single Station will count as defeat.
Observation Logs
- In Line 1 BokGak, all enemy info will be unlocked for viewing from the start. Prepare the appropriate strategy, Identity, and E.G.O loadout based on this information.
- In Line 1 BokGak, damage bonus based on Observation Levels does not apply in the Refraction Railway.
- In Line 1 BokGak, the updated Observation Level will be saved even if you give up or retry mid-Encounter.
<Major Changes>
- You now have the option to display Battle Hints (gimmick reading priority) on certain enemy Skills.
Clear Info
- After clearing each Station, you can view statistics such as participating Identities and damage contributions in the Clear Info menu.
<Records>
- Your Refraction Railway Line 1 BokGak stats will be recorded upon clearing the Terminus.
- View the Total Turns and Clear Turns by Station here; click the "Details" button to view the damage contribution statistics.
<Major Changes>
- Refraction Railway Line 1 BokGak does not maintain a record for all of your previous attempts.
- Please note that the Refraction Railway menu will not show any records for your previous attempts or Turn Counts.
Claiming Rewards
- Once a Station is cleared for the first time, its rewards will be sent to the "Lost & Found".
- To access the "Lost & Found" for the first time, a certain number of Enkephalin Modules will be required. Rewards that can be claimed afterward are free of charge.
- You can earn various level-up and extraction currencies here. Special rewards include 「Takeoff Module - ID Uptie」, 「Season 1 - 3★ Guarantee Decaextraction Ticket」, and 「Refraction Railway Line 1 BokGak Themed Ticket Deco」.
