Understand Flow Burn
Useful when…
- Use during Railjack missions when a temporary increase to speed and boost speed helps reposition or travel.
Effect and activation
Flow Burn occupies the Railjack Tactical Slot 3 category and has universal polarity and base drain 0. At rank 0 it increases Speed and Boost Speed by 12% for 5 seconds; rank 5 grants 25% for 8 seconds; rank 10 grants 38% for 13 seconds. Each listed version has a 240-second cooldown.
Rank investment
The listed costs are 20 Endo and 966 Credits from rank 0 to 1, 640 Endo and 30,912 Credits from rank 5 to 6, and 10,240 Endo and 494,592 Credits from rank 9 to 10. Higher ranks extend the duration and raise the listed speed bonus, but do not reduce the stated 240-second cooldown. Since the final listed rank-up cost is substantial, weigh the added duration and bonus against how often the tactical effect will be useful.
Other tactical effects
Void Cloak hides the Railjack from enemies for 35 seconds while reducing Engine Speed to 30%, with a 120-second cooldown. Battle Forge reduces Forge cooldown by 100 seconds and has a 480-second cooldown. Squad Renew heals all Railjack squad members by 75% and has a 300-second cooldown. These serve different tactical needs rather than duplicating Flow Burn’s speed increase.
Limitations and tradeoffs
- The speed boost is temporary and has a 240-second cooldown at every listed rank.
- High-rank upgrades require sharply increasing Endo and Credits.
Common mistakes to avoid
- Assuming the 240-second cooldown improves with rank.
- Treating the brief speed bonus as a permanent ship-speed increase.
