Hydra

Hydra is a consumable item in Fallout: New Vegas.

Background
Hydra is a drug developed from antivenom. Due to the Legion's disapproval of using modern medicine, some Legionaries attempted to develop a different means to help them heal damaged limbs. To do that, they combined cave fungus with antivenom, developing hydra - a curative agent which both anesthetizes and restores crippled limbs over time. Despite its origins in the Legion, this drug has since seen extensive use throughout the entire Mojave Wasteland, including NCR field hospitals.

Characteristics
Hydra appears as a "Supa Yum"-brand soda bottle with three sealed glass vials of liquid taped around its middle, each one with a thin rubber tube feeding their contents up to the mouth of the bottle.

Like a doctor's bag, hydra is used to restore health to crippled limbs, making it especially useful in Hardcore mode where stimpaks or sleeping in a bed one doesn't own (from having rented or being given the room) won't heal these injuries. It has the advantage over doctor's bags in that it is weightless and it will continue to slowly heal the crippled wounds over 60 seconds. In a tough fight, where one might receive crippling wounds several times, a single dose of hydra can heal them as they are received. Hydra also benefits from the Chemist and Day Tripper perks.

The downside is that hydra carries a 10% risk of developing an addiction. If this happens one will suffer a negative hit to statistics (-3 Endurance) unless more hydra is used, Fixer, or see a doctor.

This makes the only reliable source present in all versions of the game Jack, one of the drug dealers working at the Red Rock Drug Lab. If one has a high enough Survival skill to make the drug, a positive reputation with the Great Khans and has convinced Jack or Diane to start making medical supplies through either a Speech or Barter check (66 in both cases) he can be taught the recipe for hydra and he'll begin stocking it for sale.

Crafting
This item can be crafted by the player.
