NTE Eternal Memory is an S-Class Esper Ability material obtained from Anomaly Pilgrimage: Debt Collector. Blackbird uses Eternal Memory for her later skill upgrades in Version 1.4, and the same material has already been used by earlier characters, so some accounts may have a useful stock before Blackbird is even pulled.
The important part of farming NTE Eternal Memory is the Pilgrimage schedule. Debt Collector rewards are more restricted than normal open-world enemy drops, which makes Eternal Memory the material to prioritise before a weekly reset rather than something to leave until the end of the build.
How to get NTE Eternal Memory
- Progress the main story until Anomaly Pilgrimage: Debt Collector is available.
- Open the Anomaly Pilgrimage activity.
- Select Debt Collector.
- Clear the boss and claim the reward with Character Pixels.
- Use any eligible Pilgrimage Material Selection Box only when it closes a useful shortfall.
The direct source for NTE Eternal Memory is Debt Collector. General Anomaly Hunt bosses, ordinary field enemies and random city activities do not replace the Pilgrimage route, even though they may drop other materials Blackbird also needs.
How to unlock Debt Collector for NTE Eternal Memory
Debt Collector becomes available through main story progression around Chapter 5. Current guides place the unlock after starting that chapter and clearing its opening sequence, so a new account may need story progress before the Pilgrimage entry appears.
Once unlocked, the encounter can be selected again through the activity interface. You do not need to physically search the city for Debt Collector every time you want to claim another Pilgrimage reward.
What drops with NTE Eternal Memory
Debt Collector can reward Eternal Memory alongside Hunter Points, Hunter Guides, Beetle Coins, Magic Thread and Arcane Thread depending on the current difficulty and reward table. That makes the run useful even when Eternal Memory is the main reason you entered.
Use the live reward preview to see the current payout before claiming. Higher difficulties can improve the number of materials, but the best tier is the one your account can clear consistently without turning one weekly reward claim into a wall.
Why Blackbird needs NTE Eternal Memory
Blackbird uses NTE Eternal Memory in the higher levels of her Esper Ability progression. It is not her character ascension boss drop. That separate role belongs to Colorful Ticket Stub from Swallowtail.
Keeping those two bosses separate avoids a common farming mistake. Swallowtail opens Blackbird’s level cap, while Debt Collector supplies the later ability material. A fully ascended character can still be missing Eternal Memory for skills.
Pilgrimage Material Selection Boxes and NTE Eternal Memory
Some Pilgrimage selection boxes can provide Eternal Memory as one of their choices. These are useful for closing a gap, especially if a weekly reset is approaching and you are only a small number short.
Do not open a selector automatically if another character needs a different Pilgrimage material. Flexible boxes are most valuable when you know which exact bottleneck is stopping the next upgrade.
Best farming priority for NTE Eternal Memory
Claim Eternal Memory before spending all available Character Pixels on repeatable content. Houdinii’s Schemes, Numeral farming and Swallowtail can be revisited more freely, while missed Pilgrimage claims are harder to replace immediately.
If you already built Zankou or another character using the same material, inspect the inventory first. Existing leftovers can reduce Blackbird’s grind substantially and may change how many weekly claims are actually required.
Why NTE Eternal Memory is not dropping
Make sure you are fighting Debt Collector through Anomaly Pilgrimage and then claiming the reward. Simply defeating the boss is not enough if the reward claim is skipped or the account has reached the relevant claim restriction.
If the activity is missing entirely, continue the main story rather than farming unrelated Anomaly Hunts. If the activity is present but the reward is unavailable, check the live reset and claim information shown by the game.
Current NTE Eternal Memory farming summary
NTE Eternal Memory is one of Blackbird’s real launch-week bottlenecks because it sits behind Debt Collector rather than ordinary enemy farming. Prioritise the Pilgrimage reward, use selection boxes intelligently and then spend the remaining progression time on Colorful Ticket Stub, Numerals and ability materials.
That approach prevents the frustrating situation where Blackbird has every repeatable material ready but still cannot raise a late Esper Ability because the weekly-style boss material was left until last.
