Mentats are booster drugs from the Fallout series. It is believed that they may be a reference to a society of people from Frank Herbert's Dune universe, who were also named Mentats. They have appeared in all of the Fallout games, although their effects were altered between Fallout/Fallout 2/Fallout Tactics and Bethesda's Fallout 3. They are generally addicting drugs that provide stat bonuses to some or all of 3 S.P.E.C.I.A.L. skills (Perception, Intelligence, Charisma) that are either found, synthesized, or purchased.

Effects and Properties

Fallouts 1, 2 and Tactics

In the first two iterations of Fallout and in Tactics, they were effective in multiple ways over longer periods of time. They granted the immediate effects of 2 Perception, 2 Intelligence and 1 Charisma. After a day the player would "crash" with -4 Intelligence, -4 Perception and -3 Charisma effects applied to their character. After four days, the boost would raise again to 2 Intelligence, 2 Charisma and 2 Perception. The effects would then wear off by the fifth day.

Mentats had a 15% chance of addiction originally. Addiction gave players the day-old effects (-4 INT, -4 PER, -4 CHAR) for an entire week.

They do not weigh anything, and cost $280.

Fallout 3

In Fallout 3, Mentats granted the immediate boost of 5 Intelligence and 5 Perception, eliminating the previous boost to charisma. Mentats also no longer have per-day effects in Fallout 3. Instead, they wear off after a certain period of time and have no low periods afterward. It is possible to become addicted to mentats with frequent abuse.

They do not weigh anything, and cost 20 caps (Bottlecaps, Fallout 3's currency).

Fallout 3 also introduced 3 special "flavored" mentats, which are obtained by redeeming a prize voucher earned in the National Archives, which is obtained by completing a quiz on the Declaration of independence. It is not known whether or not you can be addicted to them specifically, at all, or in conjunction with normal Mentats.

  • Berry Mentats- Provide 5 Intelligence.
  • Grape Mentats- Provide 5 Charisma.
  • Orange Mentats- Provide 5 Perception.
