Toxin Resistance is an aura mod that reduces Toxin b Toxin damage by 2.5% per rank, up to 15% at max. This can be stacked with other teammates' to reduce the damage by 60%. Its effect is similar to Mod TT 20pxAntitoxin.

True ValueEdit

In practice, the percentage of the resistance does not represent the damage it resists. The Toxin b Toxin damage resisted is always less than the value mentioned. In fact, having a fully modded Toxin Resistance (15%) will only resist 10 Toxin b Toxin damage out of 100.[1]

The reason for this is that Warframes have the Flesh health class which is innately weak to Toxin b Toxin damage and as such will receive 150% damage from Toxin b Toxin sources.

Using the Toxin Resistance mod will reduce the bonus damage inflicted linearly instead of multiplicatively. For example, using a fully upgraded Toxin Resistance (15%) will total the odds between the resisted damage and the original damage by (150%-15%):150% = 135%:150%, or 90%:100%, or 9:10. Therefore, it can be concluded that all Warframe with fully modded Toxin Resistance only resists 10% instead of 15% of Toxin b Toxin damage, which determines the Toxin Resistance's True Value formula to be:

True Value = Value × 2 ÷ 3


  • For a short time after Update 10.6 this mod could have been acquired via Transmutation.[2] This was due to a bug where all mods, including unreleased ones such as this one, became obtainable through transmutation. This has since been fixed, but players who obtained the mod this way were allowed to keep them.
  • As of Update 21, this mod can be obtained from the Grineer Nox unit.


  • As of Hotfix 11.0.6 all unreleased mods were made untradeable.
  • Hotfix 13.8.4 increased the effects of this mod to provide 2.5 per level, from its previous 0.8.
