Level perks

Level perks are perks which work in the same way as their counterparts from the original Fallout games.

A player is given the possibility of gaining one level perk every 3 levels, last is on 27 level and player can delay choose of it till 29 level, Chosen One Class perk have extra 2 level Perks

Note: Level perks work off your permanent S.P.E.C.I.A.L so if want to take Adrenaline Rush, you will need real 6 Charisma (base + perks + implants) it doesn't effect temporary special like from Drugs or Armor Perks.
If perk require other stat than special like Melee Damage you can boost your stats by drugs or other temporary source.
It is worth mentioning however that SPECIAL Boy Perk Synergy allows you to use temporary S.P.E.C.I.A.L sources as if those were permanent, thus giving you more freedom in your character's build creation.
