NTE Crime and Punishment Arc is Blackbird’s limited S-Class signature Arc in Version 1.4 and is available through the Roostfeather Special Arc Research Program from September 30 until October 21 at 05:59 UTC+8. You can use Tri-Keys or Roostfeather Keys to research for it once the Arc system and required story progression are unlocked.
The main reason to target NTE Crime and Punishment Arc is synergy rather than rarity alone. Crime and Punishment is built around Blackbird’s Psyche damage and Ultimate cycle, improving her own burst while also contributing CRIT-related team value after the Ultimate is used.
How to get NTE Crime and Punishment Arc
- Complete the required early main story progression to unlock the relevant research systems.
- Open Arc Shop.
- Select Arc Research Program.
- Choose the Roostfeather Special program.
- Spend Tri-Keys or Roostfeather Keys on research.
- Claim the Arc if you obtain it before the program ends.
NTE Crime and Punishment Arc is currently only available through the Roostfeather Special research program. It is not listed as a permanent shop purchase or ordinary boss drop in the Version 1.4 notes.
When does NTE Crime and Punishment Arc end?
The Roostfeather Special program runs from the Version 1.4 launch on September 30 until October 21 at 05:59 UTC+8. That is the same first-half window as Blackbird’s Foretold Finale character board.
Convert the closing time carefully if your local timezone differs from UTC+8. The safest final check is the countdown shown inside the Arc Research Program because maintenance or regional display can make a calendar conversion look confusing.
What does NTE Crime and Punishment Arc do?
Current live Arc data shows NTE Crime and Punishment Arc as a Gas S-Class weapon built for Psyche damage and Ultimate-driven CRIT support. Its scaling includes Cycle Intensity, Psyche DMG, a team CRIT DMG increase after the wearer casts Ultimate, and an additional CRIT DMG increase for the wearer during the burst window.
That package explains why it fits Blackbird so cleanly. Her build already wants CRIT and a reliable Ultimate cycle, so the signature Arc reinforces the same priorities instead of forcing a completely different stat direction.
Is NTE Crime and Punishment Arc Blackbird’s best Arc?
For a premium Blackbird build, yes. Crime and Punishment is the purpose-built signature released with her, and current launch builds place it at the top when the goal is to maximise Blackbird’s own contribution.
That does not make Blackbird unusable without it. Gas alternatives such as Blow up the Crowd can still support Psyche-oriented play, and a strong existing Arc can be preferable to draining every Annulith after already winning the character board.
Tri-Keys and Roostfeather Keys for NTE Crime and Punishment Arc
The research program accepts Tri-Keys or the event-specific Roostfeather Keys. Check what the account already owns before converting or spending premium currency because event keys are designed for the current research program while Tri-Keys are broader resources.
If you are also pulling Blackbird’s character board, plan both budgets together. A signature Arc is an upgrade to a character you own, while an Arc without the intended character may sit unused depending on the rest of your roster.
Should free-to-play players pull NTE Crime and Punishment Arc
Pull only if Blackbird is a real account priority and the character side is already secure enough that the Arc will be used. The signature improves her premium ceiling, but Version 1.4 also contains Pukaland rewards, future banners and a second-half character, so every key spent has an opportunity cost.
A good stopping point is to build Blackbird with Devil’s Blood: Curse and a non-signature Gas Arc first. If the team already clears the content you care about, the signature becomes a luxury rather than a requirement.
Current NTE Crime and Punishment Arc summary
NTE Crime and Punishment Arc is obtained from Roostfeather Special, runs until October 21 at 05:59 UTC+8 and is the cleanest premium Arc for Blackbird’s Psyche and Ultimate-focused setup. Use Tri-Keys or Roostfeather Keys, then build the rest of the character around CRIT and her Type III Console specialization.
Because the program is limited, do not confuse it with a permanent Arc shop entry. If you want the signature, use the live research countdown as the deadline and decide before the first Version 1.4 phase ends.
