X-Cell (Fallout 4)

X-cell is a consumable item in Fallout 4.

Background
Created before the war as a general performance enhancer, X-cell never got out of the prototype stage, but was widely distributed on the black market. It boosts every SPECIAL attribute for a limited period of time, but is highly addictive.

Characteristics
It appears to be some sort of inhaler; it boosts all S.P.E.C.I.A.L. attributes by 2 points for a limited duration. According to the Survival Guide, this duration is 120 seconds. With an addiction rate of 35%, X-cell is 20% more addictive than any other chem in the game. Because of its rarity, carrying some addictol is recommended, as taking doses simply to sustain an addiction is not feasible, and the penalties of addiction are high.
