Blizzard says it felt a greater sense of pressure when developing Diablo 4's new Spiritborn class because it doesn't fit into the conventional tabletop RPG model like the action RPG's existing classes.
Diablo 4's current available classes include Barbarian, Sorceress, Druid, Necromancer, and Rogue, and despite being unique visually and mechanically, they aren't at all specific to the Diablo franchise. Spiritborn, however, is a Diablo invention – jungle predators that can summon Spirit Guardians that take the shape of jaguars, gorillas, eagles, and giant centipedes to aid you in combat.
