Diablo IV is a 2023 online-only action role-playing game developed and published by Blizzard Entertainment. It is the fourth main installment in the Diablo series. Announced at BlizzCon 2019, the game was released on June 5, 2023 for the PlayStation 4 and PlayStation 5, Xbox One and Xbox Series X and S, and Microsoft Windows. Players create a character from one of five playable classes—Barbarian, Druid, Necromancer, Rogue, or Sorcerer—and use their skills to complete quests through combat.
The core formula for the series’ gameplay revolves around gradually obtaining stronger equipment by defeating increasingly difficult enemies. Enemies are fought using different character class skills which can be customized by equipment and talent trees. This concept is used to progress through the story and quests. Enemies are split into monster families which are defined by a theme, combat style, and their location. Each family contains different archetypes that hold different roles allowing for synergies of specialty abilities between family members. To differentiate between them, they have unique silhouettes, stances and weapons.
The playable character’s effectiveness in combat is determined by their attributes and their boosts from equipped items. Offensive attributes include attack and critical chance which increase damage output. Defensive stats include elemental resistance and defense which increase how much damage can be taken. Diablo IV introduces three new attributes: Angelic, Demonic, and Ancestral Power. Angelic and Demonic Power alter the duration of beneficial and negative effects respectively. Ancestral Power increases the chance of effects being applied to another entity. Weapons and gear have increasing rarity which are a general indicator of their power. The rarest items have unique effects that alter more than just the character’s parameters.
