Flawed Ammo Drum GUIDE
Understand Flawed Ammo Drum
Useful when…
- Add a small ammo-capacity increase to a rifle.
- Use a Rifle Exilus slot for the flawed variant’s ammo bonus.
Effect and slot
Flawed Ammo Drum gives +2.5% Ammo Maximum at rank 0, +7.5% at rank 2, and +10% at rank 3. It is a flawed Rifle Exilus mod with Naramon polarity and base drain 2. It is incompatible with Ammo Drum.
Rank costs and comparison
The final upgrade step from rank 2 to 3 costs 40 Endo and 1,932 Credits. Standard Ammo Drum has a maximum listed bonus of +90% Ammo Maximum, so the flawed mod’s +10% is substantially smaller. Ammo Drum is also an Exilus mod, but the two are explicitly incompatible.
Scope
Its listed effect changes ammo maximum only. Aerial Ace’s on-kill double-jump refresh and Agile Aim’s Conclave aiming movement bonus are separate Exilus effects, not ammo-capacity alternatives.
Limitations and tradeoffs
- The flawed variant’s maximum capacity bonus is much smaller than standard Ammo Drum’s.
- Uses a Rifle Exilus slot.
Common mistakes to avoid
- Equipping it with Ammo Drum, which is explicitly incompatible.
- Assuming the flawed +10% capacity matches the standard mod’s +90%.
