| ||For the Psycho that appears in the Fallout series, see Psycho.|
Slasher is a chem which combines the effects of Med-X and Psycho into a single drug. This drug can be used together with Med-X to gain 50% Damage Resistance. The damage bonus effect, however, does not stack with Psycho.
- With Chem Resistant, Old World Gourmet Dead Money and Big Brained Old World Blues (add-on) the chance of addiction is only 3%, while employing a 33% longer duration if the player possesses Day Tripper as well.
- Although it requires a stimpak in its recipe, there is no healing effect administered.
