Grim Dawn's skill classes are known as Masteries. Each Mastery has its own skill tree which represents the various character archetypes within the game. On reaching level 2, a player chooses a Mastery for their character to specialize in. At level 10, a second and final mastery may be chosen to complement the first choice and create a dual-class character.
Skills can be unlearned by visiting a Spirit Guide who will refund skill points for a small fee, which will increase the more skill points are refunded. You cannot completely unlearn a skill without first removing all points from passive skills which affect it. You also cannot remove points from the Mastery bar.
