As players increase their character's level in Diablo 4, they may be looking for more of a challenge through a higher difficulty, which can be found when they unlock World Tier 3: Nightmare. Offering stronger enemies, greater dungeon challenges, and therefore even better loot, players can think of World Tier 3 as the next step after beating the game once. However, players must pass a certain test in order to gain access to a new World Tier.
