Understand Flawed Expel Corpus
Useful when…
- Adding a Corpus-specific damage multiplier to a pistol.
- Using a low-drain, low-rank faction mod option.
Effect and restrictions
Flawed Expel Corpus is an Uncommon flawed pistol mod with Madurai polarity, base drain 2, and maximum rank 3. It multiplies damage to Corpus by x1.03 at rank 0, x1.08 at rank 2, and x1.1 at rank 3. It is explicitly incompatible with Expel Corpus and Primed Expel Corpus, so it cannot be equipped alongside either named version.
When to use it
Use it when you want the listed Corpus-specific multiplier and the flawed mod’s lower base drain is useful for your pistol capacity. The standard Expel Corpus reaches x1.3 at max rank, while Primed Expel Corpus reaches x1.55; both have base drain 4. Accelerated Isotope is a different kind of pistol mod, providing Radiation and Fire Rate bonuses rather than a Corpus faction multiplier, so it is not a direct substitute for this effect.
Rank investment
The mod reaches its listed maximum at rank 3. Costs rise from 20 Endo and 966 Credits for ranks 0 to 1 to 80 Endo and 3,864 Credits for ranks 2 to 3. The final step adds two percentage points to the displayed multiplier, from x1.08 to x1.1. The standard and Primed versions offer higher listed multipliers but also have base drain 4 and cannot be used alongside this flawed version.
Limitations and tradeoffs
- Its multiplier applies to Corpus rather than being a general pistol damage bonus.
- The flawed version has a lower listed maximum than the standard and Primed variants.
- Named incompatibility prevents equipping it with Expel Corpus or Primed Expel Corpus.
Common mistakes to avoid
- Treating the Corpus multiplier as a general damage increase against every faction.
- Trying to equip it together with Expel Corpus or Primed Expel Corpus.
- Assuming the comparison mod Accelerated Isotope offers the same faction-specific effect.
