Flawed Concussion Rounds

Flawed pistol mod that increases Impact damage at a lower maximum bonus than its standard counterpart.

Released Jul 18, 2014

Flawed Concussion Rounds adds Impact damage to pistols, reaching +32% at max rank. It can serve as an available Impact option, but its listed maximum is lower than standard Concussion Rounds and the two are explicitly incompatible.

Understand Flawed Concussion Rounds

Useful when…

  • Use on a compatible pistol when adding Impact is desired and the flawed variant is the available option.
  • Consider replacing it with the standard version when available and when its stronger Impact bonus suits the build.

Effect and rank

The mod grants +8% Impact at rank 0, +24% at rank 2, and +32% at rank 3. It is a Flawed variant for pistols, with Naramon polarity and base drain 2. Its effect is limited to Impact damage; no fire rate or other bonus is listed.

Slot and investment

It is a standard-slot mod with maximum rank 3. The rank 2 to 3 example step costs 80 Endo and 3,864 Credits. Rank it when the extra Impact is useful enough to justify those resources and the slot; the input lists no acquisition drops for this flawed variant.

Standard counterpart

Standard Concussion Rounds reaches +90% Impact and has maximum rank 5, compared with this flawed mod's +32% at rank 3. The standard version is the relevant upgrade when accessible, but the two are explicitly incompatible and cannot be equipped together. Accelerated Isotope provides Radiation and fire rate instead, so it addresses different goals.

Limitations and tradeoffs

  • The flawed variant caps at +32% Impact, below the standard counterpart's +90%.
  • Uses a standard slot and additional rank investment.
  • Explicitly incompatible with standard Concussion Rounds.

Common mistakes to avoid

  • Equipping it with standard Concussion Rounds despite their explicit incompatibility.
  • Treating the listed Impact bonus as a bonus to all damage types.
