Understand Flawed Shell Compression
Useful when…
- Add a small reserve-ammunition increase to a compatible shotgun when using the flawed version.
Effect and use
At rank 0 it adds 3% maximum ammunition, rising to 9% at rank 2 and 12% at rank 3. It affects ammunition capacity; it does not increase damage or change firing behavior.
Slot and investment
This is a shotgun Exilus mod with Naramon polarity, base drain 2, and a maximum rank of 3. Fusion uses Endo and Credits; the listed final step from rank 2 to 3 costs 80 Endo and 3,864 Credits. Since the maximum bonus is modest, rank it according to how much extra capacity you need and the value of those resources to your other upgrades.
Limitations and alternative
The mod is explicitly incompatible with Shell Compression, so treat the standard and flawed versions as alternatives rather than a pair. The standard mod reaches +90% maximum ammunition, but uses five ranks; consider it when available and a larger reserve increase is useful.
Limitations and tradeoffs
- Small maximum-ammunition bonus compared with the standard version.
- Uses an Exilus slot that could hold another compatible Exilus mod.
Common mistakes to avoid
- Expecting the mod to improve damage or fire rate.
- Trying to equip it with Shell Compression.
