Experience
From The Secret World Wiki
Experience is a common reward for accomplishing tasks in The Secret World. It is a main element in character progression. It can be earned through completing missions, killing monsters in PvE, or defeating enemies in PvP.
Experience Bar
The experience bar tracks earned experience and progress towards Ability Point and Skill Points. It takes 120,000 experience to fill the bar, upon which the player earns a Skill Point. Every 1/3rd of the bar, 40,000 experience, an Ability Point is awarded. These amounts do not increase as the player gains more points, unlike many MMOs.
