Diablo 2 - PC Gamer November 1998 article (Alpha version)
I found an interesting Diablo 2 article in one of my older video game magazines. It covered the game during its Alpha stage. Game play and characters are far from final. For example, the Necromancer is listed as having skill trees Curses, Summoning, Mind Control. It seems like Poison and Bone was added later, to give him some direct damage of his own.
