The way Blizzard speccifies your character's characteristics in Diablo 4 is a blend of the studio's approach to Diablo 2 and Diablo 3. The executive producer and director of the Diablo franchise Rod Fergusson put D2R Items, "Diablo 2 was like locking yourself in; you had the option of respeccing every time you faced a challenge. But with D3 you kind of changed your character like you changed your clothes. Everything was gear-based as opposed to skill-based."Fergusson added, "I think the fact that we have skills on the equipment [in Diablo 4] is really nice for experimentation -- as a sorceress I [might] get Blizzard [on a pair of boots] three levels before I should and I can try Blizzard to see if I actually want it."

Game Director Joe Shely told Polygon in an interview with a roundtable during a roundtable discussion that "having your character appear to be a collection of choices you made can lead to interesting choices, or at least interesting opportunities."Shely stated she believes that the Diablo staff is cognizant that game players especially those who are just beginning their journey won't be fully aware of each class' set of abilities. The players will want to try different classes.

"When you consider our respec system," Shely said, "which can be applied to both the skill tree and to Paragon for the higher levels, which is our endgame development system. "We've tried to approach the system in a manner that has the sense that making a decision is important and that your character's not the same as everyone other character, however there is plenty of choice to try things out.

"You've had the option of specify points point by point. Simply click to stop spending a point and then spend it on another thing however, as you progress higher into levels, the price increases, making those choices a little bit more considered. Of course, you can also revise your entire buy diablo 2 resurrected items tree in one shot if you would like to build from the ground up."
