Fallout 4 Perks

General information
The new perk system of Fallout 4 has now merged with the skill system of previous games. There are a total of 70 attribute-based perks, with 229 ranks spread across them, and the player is able to choose one perk every level. Perks have level requirements but not skill requirements; instead, the 70 perks are divided up into groups of 10 under each of the 7 SPECIAL stats, with each of the perks requiring a different value for that stat, from 1 to 10.

Players do not get a perk at level 1; otherwise, every level, a player can either pick up a perk or an attribute point. There are 8 external attribute point sources in the game after creation - a bobblehead for each attribute, and a magazine that adds an attribute point of the player's choice - in addition to the 28 points at the start of the game. Given this, and the fact advanced players may choose not to pick up bobbleheads until base SPECIALs have already been raised to 10 (raising the base SPECIALs to 11 with bobbleheads), the maximum effective level is 272 for 10 or 11 in each attribute, and maximum rank in every perk.

Separately, there are perks you can gain by reading magazines and perks you can gain by winning favor with a companion.

SPECIAL perks
Below a list of perks attainable from the perk chart. Note that the columns can be sorted on each column; for example, sorting by level is possible. To sort by multiple columns, hold down shift while selecting columns to sort by.

Magazine perks
Perks that can be acquired by reading magazines.

Companion perks
These perks are acquired by reaching the maximum level of friendship with a companion. The perks obtained this way are permanently obtained, whether you keep travelling with the associated companion or not.

Special Stats
Leveling a S.P.E.C.I.A.L. stat is actually gaining a perk. Levels 2-10 of every stat have their own perk code that can be added via. Level 1 of every stat is the starting point, and is thus not a perk). Like regular multi-level perks you should add prerequisite levels; for example, if you wish to add a level 3 Intelligence you should first add level 2.

Bobblehead perks
Each bobblehead that doesn't increase a SPECIAL stat has its own unique perk and ID.

Secret/hidden perk(s)
Those perks are ONLY available through console commands and will NOT appear in your Pip-boy.

*Since the Critical perk basically gives a permanent Overdrive effect it's currently unknown if it stacks with the Chem.
