Idiot Savant is a perk in Fallout 4.

## EffectsEdit

Rank Requirements Description Base ID
1 LCK 5 You're not stupid! Just... different. Randomly receive 3x XP from any action, and the lower your Intelligence, the greater the chance. 001d245e
2 LCK 5, LVL 11 You now randomly receive 5x XP from any action. The lower your Intelligence, the greater the chance. 001d245f
3 LCK 5, LVL 34 Randomly receiving bonus XP from any action may trigger 3x XP for all kills for a short period of time. The lower your Intelligence, the greater the chance. 001d2460

For ranks 1 and 2, the perk randomly activates whenever you gain experience from any source. At 1 Intelligence, the chance of activation is 11%, and you lose 1% per added point of Intelligence. The chance minimizes at 1% at Intelligence 11 or higher.

When the perk activates, you will see a laughing Vault-Boy above the compass, and hear a laughing sound. The experience you would have earned will instead be boosted to 3x (for rank 1) or 5x (for rank 2+). This boost is multiplicative with any normally additive experience bonuses from being well-rested or having a high Intelligence.

The probability for the "kill bonus" from rank 3 appears to be independent of the bonus experience from rank 1 and 2 and the probability of it triggering is currently unknown. The effect lasts 60 seconds.

### Comparison to IntelligenceEdit

$AvgExpMulti = 1 + \Bigg(\frac{min(2,IdiotSavantLevel) \times %Chance}{50}\Bigg)$
$OverallExp = IntMulti \times AvgIdiotSavantExpMulti$

When comparing a perk point to put into higher Intelligence or Idiot Savant, it is worth comparing the returns you get. Each point in Intelligence improves experience gain by 3%. Consulting the above table, it can be seen that with two levels of this perk, average experience gain is optimized at 2 INT and actually drops with each additional Intelligence point until very high levels of Intelligence.

## NotesEdit

• One can potentially exploit any quest for a huge amount of experience. This can be done via saving before finishing a quest and reloading the game until the perk triggers the multiplication.
• When turning in a quest where the final step requires speaking to someone, you can Quicksave mid-conversation just before the final lines of dialogue are spoken. This will save some time with reloading.
• Idiot Savant events are tracked in the Pip-Boy Data under "Bright Ideas".
• When Idiot Savant rank 3's kill experience activates, it temporarily shuts off the chance of getting bonus experience. Because of this, rank 3 may be a net loss of expected exp, depending on play style.
• When the 3rd rank of Idiot Savant triggers a blank perk with no name, description or picture will appear at the top of the perk list under stats. This represents the temporary 3x exp kill bonus.

## Behind the scenesEdit

The term idiot savant refers to an individual who is overall mentally disabled but nonetheless displays an exceptionally high level of ability in performing a specific task such as memory, arithmetic, art, or music.

## BugsEdit

• xboxone If the Idiot Savant perk activates when turning in Reunions or Learning Curve, you will sometimes not get the 3x or 5x multiple of experience points.[verification overdue]
