Summary

  • Invest perk points in Fallout 4 to enhance abilities and gameplay; perks in the Intelligence column include descriptions.
  • Gun Nut grants access to craft advanced weapon mods at weapon workbenches, offering self-sufficiency and more sophisticated mods with each rank.
  • The Chemist perk increases chem duration by 50% per rank, enhancing stat buffs and beneficial effects.

Intelligence is the "I" in Fallout's S.P.E.C.I.A.L. Stats. Unlike in previous games, this stat does not govern skill checks. Instead, it increases the amount of experience that players gain from all sources by 3.33%. Players with high Intelligence scores will also see fewer possible passwords when hacking terminals, making hacking easier with more points in this stat.

Fallout 4: 8 Overpowered Builds That Are A Lot Of Fun

Putting together a focused character build in Fallout 4 can generate some very overpowered results, something these builds excel at.

Most of the Intelligence perks in Fallout 4 are great. Unlike Luck Perks, there is not a uniform theme to Intelligence Perks. Instead, they grant bonuses to a wide range of things, from crafting to chem usage to life-saving buffs at low health.

15 V.A.N.S.

Let V.A.T.S. Guide You To The Objective

Vault Boy rides a small van like a horse

Rank

Requirement

Description

1

Intelligence 1

The path to your closest quest target is displayed in V.A.T.S.

2

Intelligence 2

Gain +2 to Perception.

V.A.N.S. Allows players to see the quickest path to their current objective. After unlocking this perk, the V.A.T.S. Display will show an opaque line over the shortest distance to get to their marked objective. While this can be useful for guiding players out of the larger, more labyrinthine buildings in the downtown area, there is not a lot of utility in this overall.

The Nuka World DLC added a second rank to this perk, which grants players a permanent +2 bonus to their Perception stat. While this is nice, many players would agree that it is not necessarily worth investing two points in this perk just for the bonus.

14 Gun Nut

Build Gun Mods Yourself

Rank

Requirement

Description

1

Intelligence 3

You gain access to base level and Rank 1 gun mods

2

Intelligence 3, Level 13

Gain +2 to Perception.

3

Intelligence 3, Level 25

You gain access to Rank 3 gun mods

4

Intelligence 3, Level 39

You gain access to Rank 4 gun mods

The Gun Nut perk allows players to craft their own gun mods at weapon workbenches. Each rank grants access to more sophisticated mods, such as an ignition module that adds fire damage to the Junk Jet's projectiles. For players who enjoy crafting their own things and staying as self-sufficient as possible, this is a great perk.

However, players can also find weapons with the mods attached while exploring. Gun Nut is not needed to use these existing mods on weapons; it only adds the ability to craft them. Therefore, players who are patient (or who have the caps to purchase mods from vendors throughout the Commonwealth) don't really need to invest perk points here.

13 Chemist

Get More Benefits From Chems

Rank

Requirement

Description

1

Intelligence 7

Any chems you take last 50% longer.

2

Intelligence 7, Level 16

Any chems you take last twice as long.

3

Intelligence 7, Level 32

Any chems you take last an additional 150% longer.

4

Intelligence 7, Level 45

Any chems you take last an additional 200% longer.

While some players avoid using chems for the sake of roleplaying or just because they don't want to rely on drugs in-game, chems can be extremely useful for surviving the post-apocalyptic world of Fallout. Chems like Buffout improve melee damage and carry capacity, while Mentats can help players get rich by improving bartering prices.

The Best Chems In Fallout 4, Ranked

Fallout 4 allows the player to use chems, but which ones are the best and most useful?

Each rank of the Chemist perk extends the duration of all chems by 50%. The extra time with buffs to stats can be a game-changer, especially when players have invested points to unlock all four of this perk's ranks. While it may not be for everyone, this perk can be incredibly beneficial.

11 Scrapper

Turn Unwanted Gear Into Useful Junk

Rank

Requirement

Description

1

Intelligence 5

You can salvage uncommon components like screws, aluminum, and copper when scrapping weapons and armor.

2

Intelligence 5, Level 23

You can salvage rare components like circuitry, nuclear material, and f iber optics when scrapping weapons and armor. Items with favorited components are highlighted.

3

Intelligence 5, Level 40

Earn more from salvaging.

Fallout 4 can easily collect a lot of unwanted weapons and armor while exploring the Commonwealth. Fortunately for them, they can sell these items to make some quick caps or use a weapon workbench to salvage them for useful crafting items.

The Scrapper perk allows players to receive uncommon (at rank 1) and rare (at rank 2) junk items when salvaging weapons and armor. With the Far Harbor DLC, there is a third rank which grants even more salvage. This can be helpful for players who just need a specific set of items to craft that next weapon mod or to round out their favorite settlement.

10 Nerd Rage!

Gain A Damage And Resistance Boost When Low On Health

Vault Boy bulks up and rips through his jumpsuit

Rank

Requirement

Description

1

Intelligence 10

When your Health drops below 20%, time slows and you gain +20 Damage resistance and do 20% more damage while the effect lasts.

2

Intelligence 10, Level 31

You now gain 30 more Damage Resistance and do 30% more damage while Nerd Rage is in effect.

3

Intelligence 10, Level 50

You now gain 40 more Damage Resistance and do 40% more damage while Nerd Rage is in effect. Kills you make while enraged restore some lost Health.

The final perk of the Intelligence column is Nerd Rage, which helps players stay alive when their health falls below 20% of the maximum. Time slows down, players gain 20 damage resistance, and their damage output increases by 20% when they are at low health, just from the first rank of Nerd Rage. Each subsequent rank adds 10 damage resistance and an extra 10% damage.

Fallout 4: All Strength Perks, Ranked

Strength perks in Fallout 4 do everything from improve the Sole Survivor's total carry weight to increasing their unarmed and melee attack damage.

While it may not function for a huge amount of time like the solar-powered perk, having this perk can mean the difference between life and death in dire situations.

9 Nuclear Physicist

Improve Radiation Weapons And Fusion Cores

Vault Boy holds an atom with a smiling nucleus

Rank

Requirement

Description

1

Intelligence 9

Radiation weapons do 50% more damage and Fusion Cores last an extra 25% longer.

2

Intelligence 9, Level 14

Radiation weapons now do double damage and Fusion Cores last an extra 50% longer.

3

Intelligence 9, Level 26

Fusion Cores can be ejected from Power Armor like devastating grenades and Fusion Cores last twice as long.

This perk is essential for players that use Power Armor since it increases the duration of Fusion Cores that the suits use as a power source. With all three ranks of Nuclear Physicist, Fusion Cores last twice as long as they do by default, making it so that players don't need to collect and carry as many of them as they would otherwise. This is especially nice for Survival players since Fusion Cores weigh four pounds each as part of the added difficulty.

The other aspect of this perk is that it boosts the damage output of radiation weapons, which is a nice buff for players looking to roleplay as Children of Atom or those who like to irradiate their enemies.

8 Science!

Use High-Tech Mods For Weapons And Armor

7 Vault Boy holds an energy weapon and mod in his hands

Rank

Requirement

Description

1

Intelligence 6

Take full advantage of advanced technology with access to base level and Rank 1 high-tech mods.

2

Intelligence 6, Level 17

You gain access to Rank 2 high-tech mods.

3

Intelligence 6, Level 28

You gain access to Rank 3 high-tech mods.

4

Intelligence 6, Level 41

You gain access to Rank 4 high-tech mods.

The various ranks of the Science! Perk unlocks access to the tiers of high-tech mods in the game. These include weapon mods like automatic barrels for laser weapons and the electrified mod for blades. There are also Power Armor mods that require this perk like the Jet Pack, which requires all four ranks of this perk, and the Armorer perk.

The Science! Perk also grants the ability to craft more advanced turrets at settlements, making it a key perk to have for players who want to maximize their defense. This is a great perk to have for its variety of uses.

6 Hacker

Hack Into Any Terminal

Vault Boy operates a terminal and gives a thumbs up

Rank

Requirement

Description

1

Intelligence 4

Knowledge of cutting-edge computer encryption allows you to hack Advanced terminals.

2

Intelligence 4, Level 9

You can hack Expert terminals.

3

Intelligence 4, Level 21

You can hack Master terminals.

4

Intelligence 4, Level 33

When hacking, you never get locked out of a terminal when things go wrong.

Each rank of the Hacker perk allows players to hack into more sophisticated terminals. At rank 1, players can hack Advanced terminals. At rank 2, they can hack Expert terminals. At rank 3, they can hack Master terminals, which means that no computer in the game is beyond their reach. The fourth and final rank prevents players from getting locked out of a terminal if they get the password wrong, which is nice but not as useful as obtaining the first three ranks.

Players can also order certain companions like Nick Valentine or Ada to hack into terminals if they don't want to invest perk points into Hacker. However, that means they have to use these companions, and sometimes there is a terminal too tough to crack for even them.
