In Blizzard's latest quarterly update on Diablo IV Gold, the game's director, Luis Barriga, and the dev team shared new details about the forthcoming title. While launch day is still a long time away—even by Blizzard's own generous, internal standards—it's already clear that Diablo 4's skill system is shaping up to be very different from its predecessor's.

Diablo 3 released for PC over eight years ago and franchise fans are eager for a fresh campaign against the forces of hell. Diablo 4 is making several changes to the long-running action RPG's standard demon-slaying formula, most notably, the inclusion of open-world exploration. 

The most recent update focused on the game's mechanics and skill trees. As revealed in previous updates, every Diablo 4 class will have a distinguishing mechanic, like the barbarian's arsenal system, allowing players to easily switch between weapons. 

The character's skills will be modified by a two-fold skill tree comprised of roots and branches. Players modify and gain active abilities by spending points in the branches, which in turn unlocks points that can be spent on the roots for passive abilities.

The developers also noted that buy Diablo 4 Gold players will not be able to acquire every skill in a single playthrough, and may in fact require multiple characters to fully explore a single class. This adds tremendous weight to every build decision.
