Poison Resistance

Poison Resistance is derived statistic in Fallout, Fallout 2, Fallout 3, Fallout 4, Fallout 76, Fallout: New Vegas and Fallout Tactics.
This statistic reduces poison damage by a percentage as well as the chance to get poisoned. In Fallout 3 and Fallout: New Vegas, this statistic is hidden.
==Fallout, Fallout 2, Fallout Tactics==
:\text{Initial Level}=\text{Endurance}\times5
* The Fast Metabolism trait sets initial Poison Resistance to 0.
* The Snakeater perk increases Poison Resistance by 25% per rank.
* The Vault City Inoculations perk increases Poison Resistance by 10%.
===Notes===
* The average NPC has a 25% Poison Resistance.
* In Fallout, Poison Resistance is capped at 100%, although it cannot be raised past 75%.
* In Fallout 2, it is capped at 95%.
==Fallout 3==
Poison Resistance is also present in Fallout 3. It plays a much smaller part than in the previous games since only a few enemies (Radscorpions chief among them) use poison, and poison effects tend to be weak.
:\text{Initial Level} \%=(\text{Endurance}-1)\times5
Example: A starting Endurance of 5.
:(5-1)\times5=20\%~\text{Poison resistance}
* The Cyborg perk can increase resistance by +10%.
* The Survival Expert perk can add between an additional +2% to +6%.
==Fallout: New Vegas==
Fallout: New Vegas uses the same equation as Fallout 3, but Poison Resistance has much more use: there are cazadores, bark scorpions, night stalkers, and weapon poisons, all in addition to radscorpions. In Lonesome Road, there are also venomous tunnelers. Moreover, poison in Fallout: New Vegas is generally much more lethal. 
Honest Hearts perks
* Tribal Wisdom increases Poison Resistance by 25%.
Old World Blues perks
* Mile in Their Shoes - after consuming the nightstalker squeezin's, Poison Resistance is increased by 5%.
* Cardiac Arrest increases Poison Resistance by 50%.
* Heartless makes the player character immune to poisoning.
Items and consumables
* Gecko-backed leather armor, Gecko-backed metal armor and variants (+15%).
* Wasteland tequila (+5%, affected by Survival) and large wasteland tequila.
* Spore plant pods gives +25% resistance for 2m.
* Snakebite tourniquet cures poison and gives +85% resistance (30s).
* Antivenom, Datura antivenom and Fiery purgative cure poisoning.
* Hazmat suit (+85% resistance).
* Blood Shield (+50% up to +85% depending on the player character's Medicine).
==Fallout 4==
Poison Resistance is not a derived statistic in Fallout 4. Acquiring it is only possible via four methods:
* Astoundingly Awesome Tales #5: Grants +5 Poison Resistance.
* Legendary armor pieces with the Poisoner's modifier: Grants +25 Poison Resistance. A maximum of 5 pieces can be worn at once, totaling +125 Poison Resistance.
* Med-X: Temporarily provides +250 Poison Resistance.
* Tunnel Snakes outfit: Grants +10 Poison Resistance.
Poison damage inflicted on the player stacks and it is usually accompanied by a debuff to S.P.E.C.I.A.L. attributes. Almost all bugs inflict poison damage; some, like radscorpions and the mirelurk queen, can be quite dangerous.
===Bugs===
* If the player boosts their Poison Resistance while already poisoned the S.P.E.C.I.A.L. debuff applied with the poison becomes permanent.
==Fallout 76==
 Poison Resistance is not a derived statistic in Fallout 76 as it can be directly influenced by the player; it is not derived from any other statistic and is not a function of any other value. Players can modify their own Poison Resistance in the same manner as other resistances, through armor, perk cards, or consumables. Poison damage comes from a small variety of enemies and weapons, such as the scorchbeast queen and bug grenade.
===Poison Resistance===
Poison Resistance can be acquired via the following:
* Poisoner's armor: +25 Poison Resistance (per piece).
* Funky Duds legendary perk: +50/100/150/200 Poison Resistance.
* Tato soup¹: +10 Poison Resistance.
* Cave fungus soup¹: +10 Poison Resistance.
* Grognak the Barbarian issue #3²: +15 Poison Resistance.
* Astoundingly Awesome Tales issue #9²: +15 Poison Resistance.
* Union power armor: +150 Poison Resistance when a full set is worn.
: ¹² These share the same buff and as a result, cannot be stacked with each other.
