Jinxed

Jinxed is a trait in Fallout, Fallout 2 and Fallout Tactics.

Effects
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.
