Looks like Diablo III Beta is closer by the minute. The Diablo III Community Site was upgraded with the most juicy features to date.
Blizzard introduces the [Skill Calculator] which allows you to play around with the skills and passive skills, and explore combinations prior to playing the game.
Best yet, you can link to a specific build -- you created in the skill calculator -- via Twitter and Facebook.
You can now read the key features of each class, their active skills and passive skills with complete descriptions, and surprise ... even what each rune type does to each active skill.
Excited yet? Check it out here.
