Understand Primed Chamber
Useful when…
- Boost the first shot after a magazine is loaded.
- Compare its opening-shot bonus with a smaller version or with slot choices that improve reload behavior.
Effect and conditions
Primed Chamber is a standard-slot sniper mod with Madurai polarity, base drain 4, and max rank 3. It grants +25% damage on the first shot in the magazine at rank 0, +75% at rank 2, and +100% at rank 3. The condition is tied to the first shot in the magazine, not every shot fired.
Rank investment and alternatives
The final rank raises the listed first-shot bonus from +75% to +100%; the rank 2-to-3 step costs 120 Endo and 5,796 Credits. Charged Chamber is a separate candidate with a listed +60% first-shot bonus at max rank 5. Depleted Reload trades 60% magazine capacity for 48% reload speed, while Aero Agility grants 100% reload speed while aim gliding. Those two affect magazine capacity or reload behavior rather than the same first-shot damage condition.
Slot planning
The bonus occupies a standard sniper mod slot. Consider how often the weapon's first magazine shot is the shot you want to strengthen, and compare that with the value of other standard-slot effects in your setup.
Limitations and tradeoffs
- The damage bonus applies to the first shot in the magazine only.
- It uses a standard sniper mod slot.
Common mistakes to avoid
- Reading the +100% as a bonus to every shot in the magazine.
- Ignoring that the bonus is conditional on the first shot.
