The First Descendant: Spreading Breach & Eerie Dice Run Event Rewards
Here's how The First Descendant's Halloween events work, from Spreading Breach keys to the Eerie Dice Run board and weekend discounts.
The Halloween events in The First Descendant kicked off with the October 29, 2026 patch, and a second wave arrives after the November 5 patch. The developers shared the full list on Steam, and every event runs until November 16, 2026, at 22:59 PST.
That's five events in total, and most of them reward Dice, Keys or Ancestors Module Fragments. Below we break down how each one works, what you need to do and what you can get. You can find the details in the Game Menu (ESC) under "Event".
Spreading Breach and Eerie Dice Run
Both of these events start after the 10.29 patch and end on 11.16.2026 at 22:59 PST.
Spreading Breach
Completing Sigma Sector, Axion Plains Infiltration Operations, Infiltration Operation: Hard (400%), Karel's Mothership or Onslaught gives you a chance to see a Mutated Dimensional Stone. Opening one costs 100 Dimensional Stabilization Keys, and the odds of a stone appearing vary by content. You earn keys from six Breach Blocking Operation missions, each worth 10 keys and completable once during the event:
- Operation I: complete Infiltration Operations with a 400% multiplier 2 times.
- Operation II: complete Axion Plains Infiltration Operations 2 times.
- Operation III: complete Sigma Sector 2 times, on any difficulty.
- Operation IV: complete Karel's Mothership 1 time, on any difficulty.
- Operation V: complete Onslaught 1 time.
- Operation VI: open Mutated Dimensional Stones 1 time.
Each stone gives one reward, such as 1,000,000 Kuiper Shards, 8 Ancestors Module Fragments, an Ultimate Alignment Device, a Transcendent Alignment Device or a Special Ancestors Module Loot with 2 guaranteed Ultimate Options.
Eerie Dice Run
Complete Challenges to earn Dice, roll them in the "Eerie Dice Run" Event UI to move across the board, and collect the item for the space you land on. You get a separate Completion Reward after each full lap. Here is where the Dice come from:
