Understand Contamination Casing
Useful when…
- Add Toxin and status chance to an Archgun setup.
- Compare its Toxin bonus with the Electricity, Cold, or Heat versions when choosing an elemental status bonus.
What it adds
At maximum rank, the mod grants +60% Toxin and +60% Status Chance. At rank 0, both bonuses are +15%; rank 2 grants +45% to each. These are mod bonuses, not a prediction of final weapon damage or status behavior.
Fit and investment
It is a standard Archgun mod with Madurai polarity, base drain 4, and maximum rank 3. Each rank improves both listed effects. The provided rank steps cost 30, 60, then 120 Endo, alongside 1,449, 2,898, then 5,796 Credits. Rank it when the combined bonuses are useful enough to justify the additional mod capacity and fusion cost.
Choosing an element
Charged Bullets, Hypothermic Shell, and Magma Chamber have the same stated maximum status bonus and Archgun fit, but provide Electricity, Cold, and Heat respectively instead of Toxin.
Drop sources
Listed sources include Profit-Taker, Blite Captain, and Fomorian Sabotage. Drop information is a snapshot and does not guarantee current availability.
Limitations and tradeoffs
- Ranking up improves both bonuses but costs progressively more Endo and Credits and increases mod drain.
- The element is fixed to Toxin; another elemental variant is needed for a different element.
Common mistakes to avoid
- Treating +60% Toxin as final damage rather than a mod bonus.
- Installing it on a non-Archgun weapon or choosing it when a different elemental bonus is intended.
