Understand Containment Breach
Useful when…
- Archgun builds seeking Radiation damage and multishot together.
- Configurations where a dual-effect mod is useful for slot planning.
Effects and equipment
At rank 3, Containment Breach grants +60% Radiation and +30% Multishot. It is a standard Archgun mod with Madurai polarity, base drain 4, and three ranks. Both bonuses apply to Archgun configurations; the listed data does not specify separate attack modes.
Practical use
It suits a build that can use Radiation while also valuing multishot. The dual bonus combines two functions in one mod, but neither figure should be read as the final damage of a complete Archgun build. Whether the Radiation component fits depends on the intended elemental configuration.
Rank investment and alternatives
Rank 0 gives +15% Radiation and +7.5% Multishot; rank 3 reaches the listed maximum. The final rank costs 120 Endo and 5,796 Credits. Dual Rounds provides +60% Multishot, while Primed Dual Rounds provides +110% Multishot; each focuses on multishot rather than also adding Radiation. Ammo Chain instead increases maximum ammo.
Common misread
Containment Breach is for Archguns, not Archmelee. Its 30% multishot and 60% Radiation are separate listed mod bonuses, not a computed final damage result.
Limitations and tradeoffs
- The mod's combined benefit is only useful when both Radiation and multishot fit the build.
- Single-purpose multishot alternatives offer different listed multishot values.
Common mistakes to avoid
- Using it as an Archmelee mod.
- Interpreting the listed bonuses as final build damage or assuming multishot is its only effect.
