|Benefits||Higher chance that failures are critical for everyone around you|
|Penalties||Higher chance that failures are critical for you|
The good thing is that everyone around you has more critical failures in combat, the bad thing is so do you!
”— in-game description, Fallout and Fallout 2
Jinxed is a trait in Fallout, Fallout 2 and Fallout Tactics.
If you or a non-player character has a failure during combat, there is a greater likelihood that the failure will be upgraded (or is it downgraded?) to a critical failure.
Behind the scenes
According to the Fallout 2 perk description file, Jinx was going to be a perk instead of a trait, but this feature was cut from the game.
