Understand Breach Quanta
Useful when…
- Create a temporary delay when a Hull Breach occurs.
- Use the pause to respond to the breach before the effect ends.
Effect and timing
At rank 0, Breach Quanta stalls a Hull Breach for 20 seconds; at rank 3 it lasts 35 seconds, and at rank 5 it lasts 45 seconds. Its cooldown is 300 seconds at all listed ranks.
Tactical slot and use
It is a universal-polarity Railjack Tactical mod for Slot 1, with base drain 0 and maximum rank 5. The described effect stalls a breach temporarily. Fire Suppression instead extinguishes one fire and has a 230-second cooldown, so it addresses a different hazard; Form Up recalls and heals crew, and Intruder Stasis freezes boarding parties.
Ranking investment
Rank increases the stall duration while the cooldown remains 300 seconds. The listed fusion examples are 10 Endo and 483 Credits for rank 0 to 1 and 160 Endo and 7,728 Credits for rank 4 to 5. A higher rank extends the response window; it does not shorten the cooldown.
Limitations and sources
The tactical effect is temporary and cannot be used again until its stated cooldown has elapsed. The supplied details list several Railjack enemy sources for the mod, including Elite Exo Flak, Elite Orm Basilisk, and Corpus Ramsled.
Limitations and tradeoffs
- A long 300-second cooldown limits repeated use.
- Ranking extends the stall duration but does not change the stated cooldown.
Common mistakes to avoid
- Treating the stall as a repair or as an effect that removes the breach.
- Assuming ranking reduces the 300-second cooldown.
