Understand Leaded Gas

Useful when…

  • Use it on Vesper 77 when weak point hits are a reliable trigger.
  • Invest ranks to lengthen the active window and increase the listed Gas damage and Status Chance bonus.

Trigger and effect

On a weak point hit, the mod grants Gas damage and Status Chance for a limited time. At rank 0 the bonus is +50% for 1 second; rank 3 gives +200% for 4 seconds; rank 5 gives +300% for 6 seconds. The effect applies to Vesper 77 as stated by the mod compatibility.

Rank and fit

Leaded Gas is a Rare, five-rank standard Vesper 77 mod with Madurai polarity and 2 base drain. Ranks increase the bonus and its duration; fusion costs rise at higher ranks. Prioritize investment based on how consistently you can trigger the weak point condition and exploit the window.

wiki.warframe.com ↗

Limitation

The listed bonus lasts only after a weak point hit and expires after its stated duration. It is not a permanent Gas damage or Status Chance increase, and compatibility is specifically Vesper 77.

Limitations and tradeoffs

  • Requires a weak point hit to activate.
  • The bonus expires after a limited duration and is specific to Vesper 77.

Common mistakes to avoid

  • Treating the bonus as continuously active without a weak point hit.
  • Installing it on a pistol other than Vesper 77.
