Pariah Dog

The Pariah Dog is a special joinable NPC in Fallout 2 found in the special encounter "A lone surviving dog."

Background
The dog will be standing in the middle of an area scattered with corpses, and will go with the Chosen One over the Party Limit if failing a Luck check. His joining gives the Jinxed trait and drops Luck to 1 (or 2 for the gifted). In battle, the Pariah Dog may runs away off the edge of the screen.

The only way to remove the dog from the party and stop it from taking up one of the NPC slots is to kill it.
 * When the Pariah Dog is removed from the party, the Jinxed trait vanishes and Luck returns to normal.
 * The Hubologists' zeta scans stop the decrease in Luck from the Pariah Dog's company. Subsequently killing the dog will thereafter restore the player character's Luck as if it remains decreased, resulting in a net gain in Luck.

Stats
The Pariah Dog has a Hit Points stat of 750.

Bugs
Zero damage instant death critical hits (possible with the Better Criticals perk) that cause the death of any NPC with scripts that would normally activate upon death, will not activate those scripts (this bug is not limited to the dog). Therefore, it is possible for the dog to die, and all the ill effects of its presence in the party, including occupying a party slot, to remain. The perk Living Anatomy makes zero damage impossible; Bonus Ranged Damage and Bonus HtH Damage probably work the same way.
