Slasher

 is a consumable item in Fallout: New Vegas.

Characteristics
This item is made at a campfire if you have a Science skill of 50. It requires: Banana Yucca Fruit (2), Psycho (1), and Stimpak (2). It essentially combines the effects of Med-X and Psycho into a single drug except it is possible to combine the effects of this drug with previously mentioned ones to gain a whopping 50% boost to both damage resistance and damage.

(please note: according to my test, after consuming Psycho,Med-X and slasher, only damage resistance increase to 50. Your damage will still remain 125%)

Locations

 * At any campfire.
