You’ll get plenty of upgrades from boss fights and dungeons, so don’t worry about optimizing your gear until you reach the endgame activities. If you find an item with a higher item power than what you have equipped, just swap it and move on. The only thing that matters is the item power number, which indicates how strong an item is. If you want to level up fast, you should minimize the time you spend on managing your inventory, selling or salvaging items, or comparing stats on your gear. TOWN IS LAVAĪs the old saying goes, time spent in town is time wasted. With more players to share the damage and aggro, you can handle World Tier 2 much easier and benefit from the increased rewards. This advice changes if you’re playing in a group, though. World Tier 1 allows you to breeze through quests and strongholds that reward you with Renown, which in turn gives you extra stat points and paragon points. While World Tier 2 gives you a 20% XP and 15% gold bonus, it also makes enemies and bosses much tougher, which can slow down your progress significantly.

My advice is to stick to World Tier 1 if you want to level up fast and efficiently. There are four World Tiers in Diablo 4: Adventurer, Veteran, Nightmare, and Torment. World Tiers are difficulty settings that affect the strength of enemies, the quality and quantity of loot drops, and the availability of endgame features. One of the key decisions you’ll have to make when leveling up is what World Tier to play on. Diablo 4: Season 1 Update 1.1.0 patch notes
