― In-game description

Psy-block is a drug appearing in S.T.A.L.K.E.R.: Call of Pripyat.

Overview[]

Psy-block gives a large increase to the player's psi-protection for a whole minute, making the player nearly immune to psychic emanations from anomalies. Its crowning purpose is for fighting controllers, as its psychic attack damage will be heavily reduced and its psychic field will be rendered almost ineffective against the player, once the drug is taken.

Acquisition[]

Psy-block is available from Bonesetter, and Professor Hermann after obtaining the achievement Research Assistant. Some stalkers may also carry some but on rare occasions.

One is found in Sokolov and Garry's room in the mobile lab. It can also be found inside the Dangerous Cave. One is located inside Lab X-8, near the document Manual for item 62.
