Hydra

Hydra is an aid item in

Background
Hydra can be found throughout the Mojave Wasteland. The NCR military have utilized it for medical purposes. Excessive use causes dilated eyes, an increased heart rate and blood pressure, excessive sweating and other symptoms typical of drug abuse. It has a distinct and noticeable smell.

Gameplay
Hydra appears as a Supa Yum!-brand fruit drink bottle with three sealed glass vials of liquid taped around its middle, each one with a thin rubber tube feeding its 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 rented bed 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 the Courier could receive several successive crippled limbs, 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, the player character will suffer from -3 Endurance unless more Hydra is used, Fixer is used, or a doctor is seen.

Crafting
This item can be crafted by the Courier.

Afterward, he can be taught the Hydra recipe and will begin stocking it for sale.
