Nigel West Dickens' Elixir

The Nigel West Dickens' Elixir, commonly abbreviated, N.W. Dickens' Elixir, is an elixir sold by Nigel West Dickens, which he claims does a number of miraculous effects, including curing diseases of all sorts, and instilling superhuman abilities to the drinker. However, it is widely known that the Elixir only provides a placebo effect, although West Dickens still sells it to unsuspecting folk, claiming it is a miraculous medical breakthrough from the east when its main ingrediant is vulture feces. However, drinking it does unlock the second level of Dead Eye.

Undead Nightmare
In Undead Nightmare, it is revealed that the Nigel West Dickens' Elixir attracts zombies, acting as bait for them. Nigel gives John a few bottles and it is then called Undead Bait by the game. John can build more Undead Bait if he wishes. In Mexico, Landon Ricketts asks John if he knows something to attract the zombies, because he knows of a way to get rid if them much faster. If John then brings Landon Dynamite and Zombie Bait, Landon will stick the Dynamite in the Zombie Bait, turning it into Boom Bait, which is like Zombie Bait, but it explodes a few seconds after being thrown.

Trivia

 * A bottle of the N.W. Dickens' Elixir can be seen in the shelf of the house in Tanner's Reach.
 * Marshal Leigh Johnson's deputy Eli can be seen drinking West Dickens' elixir at the start of the mission &quot;&quot;Spare the Rod, Spoil the Bandit&quot;. He also defends the tonic and it's seller in mission dialogue, claming "It's a miracle breakthrough from the East!" and worshiping West Dickens as a genius. He is either extremely gullible or easily trusting.
 * This may be the reason that Eli has turned. Another reason could be that he's just slow.
 * Though the elixir is bogus, John Marston acquires Dead Eye Level 2 from drinking it. It is unknown what effects caused this, seeing as other NPC's who down the tonic exhibit no Dead Eye-like abilities. This is likely just for gameplay reasons, and has no canonical explanation whatsoever.
