Each lifestyle has 3 perk trees, each one containing 9 perks. Each perk costs 1000 experience to unlock and the final perk in each tree always gives a powerful trait. Both perks and 6 unique traits can be obtained through lifestyle events. A perk can only be unlocked if all perks above have been unlocked.

On average a new perk is unlocked every few years. A character can reset all lifestyle perks once per lifetime at the cost of one {{iconify|stress}} level. Resetting the perks will also remove any final trait.
