Welcome to the 
Dimensional Stabilization Key Farming Guide for The First Descendant. The keys are required to unlock the high-tier reward boxes at the end of Breach Tracking missions, which can yield a large amount of 
Gold or 
Superconductive Cooling Units.
In this guide, we break down the most efficient farming methods to ensure you never run out.
Dimensional Stabilization Key Farming Overview
Here is a quick overview of how to best get Dimensional Stabilizations Keys in The First Descendant.
To maximize your key count, prioritize the Wall Crasher boss in Axion Plains at every full hour. You can use the TFD Discord Bot to get a notification 5 minutes before he spawns. Between spawns, the most efficient way to keep the keys rolling in is by speed-running Axion Plains missions.
| Method | Key Yield | Frequency/Time | Best For |
|---|---|---|---|
| Wall Crasher Event | 20 – 400 Keys |
Every 60 Min | Massive bulk farming & Jackpots (2.5% chance) |
| Axion Plains Missions | 1 – 4 Keys |
1:30 – 2:00 Min | Consistent, high-speed solo loops |
| ETA-0 Merchant | 20 Keys (max 600) |
Weekly (Weekends) | Passive gains via Green Voucher exchange |
1. The “Wall Crasher” Event (Best for Bulk Keys)
The absolute best way to get Dimensional Stabilization Keys is the Wall Crasher World Event located in the Axion Plains.
- Spawn Rate: This event triggers every 60 minutes.
- Alarm: You can use the TFD Discord Bot to get a notification reminder 5 minutes before the boss spawns.
- Wall Crasher Drop Chances:
- 10-30x Keys: 67.5%
- 30-50x Keys: 22.5%
- 50-150x Keys: 7.5%
- 400x Keys: 2.5%
2. Axion Plains Missions & Roaming Colossi
When the Wall Crasher Colossus isn’t active, your best bet is to cycle through short missions in the Axion Plains, must be an 
Operational Area Mission to get a key. Any Commander (Yellow-bar enemy) in this zone has a chance to drop 1–4 keys. Sometimes they also drop 20 at once, but only very rarely.
Roaming Colossi also drop keys.
3. ETA-0 Merchant
The ETA-0 Merchant spawns every weekend. You can buy 20 keys with 3 green vouchers. You can buy a total of 600 keys per Abyss/Challenge boss change (so every 1-3 months). While it’s not much, it’s a great way to get an additional 600x Dimensional Stabilization keys easily if you can farm the Abyss boss.
