Changes

The skills and their presentation evolved greatly during the game's development. See the [[skill tree]] article for a full pictorial history. As of Blizzcon 2010the Diablo III beta, skills are presented in a list categories (usually three). The categories separate the skills by function, for example, the [[Barbarian Skills]] are separated into Fury Spenders, Fury Generators, and sorted into seven tiers that Situational. The skills are unlocked at various [[character level]]s. All skills are [[active]], there are no prerequisites other than character level, and there are no synergies.

[[Traits]] were added during development in 2010, when all [[passive]] skills were removed from the skill trees. Traits have been replaced by Passives. There are unique passives or masteries and boost general character traitsfor each class now, unlike Traits, or specific skills. While many traits are which had some that were shared between the classes, granting bonuses to [[attributes]] or other common properties such as [[Lucky]] (increased gold drops), or [[Pound of Flesh (trait)|Pound of Flesh]] (increased [[health orb]] benefit), about half of the traits . Passives are unique to each classunlocked by level, providing specific bonuses just for that classlike skills.
