Stimpak (Fallout 3)

Stimpak, or stimulation delivery package, is a type of hand-held medication used for healing the body.

This item consists of a syringe for containing and delivering the medication and a gauge for measuring the status of the stimpak's contents. When the medicine is injected, it provides immediate healing of the body's minor wounds.

Characteristics
The amount of health restored by one stimpak is between 30–90 HP (36–108 HP with the Fast Metabolism perk), and is dependent on the level of the player character's Medicine skill. It is equivalent to the expression $$30 + 0.6M$$ (with Fast Metabolism, $$(30 + 0.6M) \times 1.2$$ or $$36 + 0.72M$$), where $$M$$ is the level of the Medicine skill.

Uses
In contrast to previous games, stimpaks in Fallout 3 can be used to heal crippled limbs. When used on a limb, it heals a relatively high amount of damage on the limb but slight healing on the body. Conversely, when used on the whole body, a relatively high amount of damage on the whole body is healed, but the limbs are healed only slightly. Because of this, the use of stimpaks is rather tactical. The alternative ways of healing limb damage are: sleeping in a bed, visiting a doctor, the Rad Regeneration perk from the Wasteland Survival Guide quest, or using the My First Infirmary.

Locations
Stimpaks can be found in almost every first aid box and often accompany other hand-held medical equipment on compartment trays. They also appear in the wares of most merchants.
