Jinxed

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

Fallout and Fallout 2
All misses have 50% chance to be "upgraded" to a critical miss. This applies to every single entity in the game.

Fallout Tactics
Presumably the same as in Fallout and Fallout 2, however the chance seems to be significantly lower.

Fallout Tactics
The trait does not do anything as of version 1.27.
