Flawed Antitoxin

Flawed Warframe toxin-resistance mod

Released Jul 18, 2014

Flawed Antitoxin is a lower-rank variant that grants up to 20% Toxin Resistance. Consider it when its smaller capacity cost suits a temporary or constrained build.

Understand Flawed Antitoxin

Useful when…

  • Add some Toxin resistance at low mod drain.
  • Use it as a limited alternative when standard Antitoxin is not being equipped.

Effect and rank

It grants 5% Toxin Resistance at rank 0, 15% at rank 2, and 20% at its maximum rank of 3. It is a Warframe mod with base drain 2 and Vazarin polarity.

Investment and slot

This is a standard-slot Flawed mod. Its lower maximum rank and 20% resistance cap distinguish it from standard Antitoxin, which reaches 45% at rank 5. The example cost to advance from rank 2 to 3 is 80 Endo and 3,864 Credits.

Choosing between variants

Standard Antitoxin provides more maximum Toxin Resistance but has base drain 4 and a maximum rank of 5. The two mods are explicitly incompatible, so choose one for the slot rather than planning to equip both. Adaptation has a separate trigger: it gains resistance to the damage type that hits the Warframe, stacking up to 90% for 20 seconds.

Limitations and tradeoffs

  • Toxin Resistance is capped at 20%, less than standard Antitoxin's 45%.
  • Its low base drain can help with limited capacity, but the resistance ceiling may not meet a build's needs.

Common mistakes to avoid

  • Do not assume Flawed Antitoxin can be equipped alongside standard Antitoxin.
  • Do not treat its 20% maximum as equivalent to the standard mod's 45%.
