Skill points

You gain five skill points every time you gain a level. Skill points are used to purchase skills.

NOTE: As a result of the Skill Point system change in C2, those who are in "Skill Point debt" receive 4 Skill Points per level until they are out of Skill Point debt. Those who have "Skill point credit" gain 6 skill points per level until they are out of skill point credit. Skill point debt or credit is gained when updates to the game change the cost of skills that the player already possesses, resulting in the player having more or less unused skill points than they should for their currently trained skills. Skill point debt or credit is a mechanic to allow skill costs to change without affecting players' currently unused skill points.
