The First Descendant has launched two reward events running until 16 November 2026: Spreading Breach and Eerie Dice Run. Players can earn Dimensional Stabilization Keys, Kuiper Shards, Alignment Devices, boost items, an Eerie Night UI Theme, a matching Name Card and repeatable completion rewards.
Nexon published the full event tables on 29 October alongside Patch 1.4.7. The events are available on Steam, Xbox and PlayStation 5. Dates below are converted from the official Pacific schedule; because US daylight-saving time changes during the event, UK players should rely on the in-game timer for the final hours.
The First Descendant event dates
Spreading Breach and Eerie Dice Run began after the 29 October patch and end on 16 November at 10:59pm PST. Event information appears under Game Menu > Event or through the Descendant Mission Board and BB-On.
Three supporting events begin after the 5 November patch: Special Fragment Exchange, Weekend Readjustment Discount and Today's Readjustment Benefit. These share the broader 16 November endpoint, with the discount limited to two weekend periods.
How Spreading Breach works
Completing selected content can spawn a Mutated Dimensional Stone. Target activities include Sigma Sector, Axion Plains Infiltration Operations, 400% Hard Infiltration Operations, Karel's Mothership and Onslaught.
Opening one stone costs 100 Dimensional Stabilization Keys. Six one-time Breach Blocking missions each award ten keys for completing specific activities or opening a stone, providing 60 keys before any additional event drops.
Mutated Dimensional Stone rewards
Opening a stone grants one item from the event pool:
- 1,000,000 Kuiper Shards
- Rare, Ultimate or Transcendent Alignment Devices
- Eight Ancestors Module Fragments
- One Dice for Eerie Dice Run
- Four Special Synthetic Calcium
- A Vehicle Enhancement Materials Box
- Special Ancestors Module Loot with two guaranteed Ultimate options
The Vehicle Enhancement Materials Box contains 2,000 Specially Treated Alloy, 1,000 Insulating Nuts, 400 Alloy Bearings and 400 High Conductivity Wire. Stone appearances are chance-based, and Nexon says the probability varies by activity.
How to earn Dice
Eerie Dice Run uses daily, weekly and one-time missions. Each daily mission grants one Dice for completing two Infiltration Operations, one Axion Plains Battlefield Mission, one Trials round or five missions of any difficulty. That provides up to four Dice per daily reset.
The two weekly tasks award five Dice each for three Ancestors Module readjustments and one Onslaught completion. Rolling 30 times also completes a one-time bonus mission worth eight additional Dice.
Daily missions reset at 11:00pm Pacific. Weekly missions reset each Wednesday at 11:00pm Pacific. Check the in-game countdown after the US clock change rather than assuming a fixed UK conversion throughout the event.
Eerie Dice Run board rewards
Every roll advances around the event board. Landing spaces can award:
- Gold, Kuiper and Weapon Proficiency boosts
- Descendant EXP and Unique Arche Factor boosts
- Crystallization Catalysts
- Kuiper Shards and Gold
- Rare or Ultimate Alignment Devices
- Ancestors Module Fragments
- Superheated Material and Superconductive Cooling Units
- Dimensional Stabilization Keys and extra Dice
Rewards can be earned again when landing on the same space. Board positions are therefore repeatable rather than one-time claims.
Lap completion rewards
- One lap: Eerie Night UI Theme
- Two laps: one-hour 30% Transcendent Weapon Acquisition Boost
- Three laps: Eerie Night Name Card
- Four laps: one Sub Wave Modulator
- Five laps: one Transcendent Wave Modulator
- Six laps: one Sub Wave Modulator
- Seven laps and every extra lap: three Ultimate Alignment Devices
The seventh-lap reward repeats on every additional completion, giving active players a reason to keep collecting Dice after earning both Eerie Night cosmetics.
Special Fragment Exchange and free readjustment
From the 5 November patch, dismantling an Ancestors Module once per day grants an extra fragment. BB-On's Special Fragment Exchange offers Special and Rare Ancestors Module Loot, Alignment Devices and Descendant-specific modules. Ultimate Alignment Devices cost ten fragments and have a weekly limit of five; several other exchanges are unlimited.
Ancestor Module readjustment materials are reduced by 50% during 5–8 November and 12–15 November, according to the official Pacific schedule. Today's Readjustment Benefit also makes the first module readjustment each day free during its event period.
Patch 1.4.7 and Gley changes
Patch 1.4.7 removes the 20% Fire Rate Increase from Gley and Ultimate Gley's Massacre, including the Slaughter effect from Super Senses. Nexon says the bonus stacked with Transcendent Weapon performance and pushed damage beyond the intended balance range.
The patch also adds Halloween bundles, skins, emotes, lounge decorations and figurines, but those store items are paid content and should not be confused with the free event-board rewards listed above.
