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.
