Charged Chamber

Sniper mod that boosts the first shot in a magazine.

Released May 23, 2013

Charged Chamber adds damage to the first shot in a sniper magazine. Consider it when that shot is a meaningful part of how you use the weapon; subsequent shots do not receive the listed bonus.

Charged Chamber GUIDE

Understand Charged Chamber

Useful when…

  • Boost the opening shot after loading a sniper magazine.
  • Use it when the weapon’s magazine and firing pattern make the first shot valuable.

Effect and scope

Charged Chamber grants 10% damage on the first shot in a magazine at rank 0, 40% at rank 3, and 60% at rank 5. The condition is specifically the first shot in the magazine, not every shot. It is a standard Sniper mod with Madurai polarity and base drain 6.

Ranking and slot tradeoff

The maximum rank is 5. Rank-ups increase the opening-shot bonus but require more Endo and Credits at later ranks; the step from rank 4 to 5 costs 320 Endo and 15,456 Credits. If that resource cost is not worthwhile for the opening shot’s role in your setup, a lower rank still provides the stated conditional bonus.

Related sniper choices

Primed Chamber has a larger listed first-shot bonus of 100%. Depleted Reload trades magazine capacity for reload speed, while Aero Agility grants reload speed while aim gliding. Those mods target different conditions and do not automatically replace Charged Chamber’s first-shot effect.

Limitations and tradeoffs

  • Its damage bonus applies only to the first shot in a magazine.
  • Higher ranks improve that bonus but require additional fusion resources.

Common mistakes to avoid

  • Assuming the bonus applies to every shot in the magazine.
  • Treating reload-speed or magazine-capacity alternatives as equivalent first-shot damage effects.
