Diablo 4 Season 4 Leveling Guide

This is Rob2628's best guess of the fastest way to level 100 in Season 4.

Start by choosing the class you will be playing this season. To help you get started, we recommend one of our leveling builds below:

Start the Seasonal Quest. Progress up until it asks you to gain Iron Wolf Honor from Helltides.
Do the Raising Spirits quest in Kyovashad to receive Bundled Herbs.
Craft Precision Elixir at the Alchemist.
Start doing Helltides. During the 5 minute breaks, salvage and optimize your gear, finish your Class Quest, and clear dungeons for important Aspects that your build needs.
Keep running Helltides until you are Level 35.
Complete the Capstone Dungeon.

Keep running Helltides until you are Level 55. During the 5 minute breaks, salvage and optimize your gear, and clear dungeons for important Aspects that your build needs.
Once you are ready for the Capstone Dungeon, temper your gear, upgrade your weapon, and stack Fire Resistance.

Keep running Helltides until Level 70. During the 5 minute breaks, salvage and optimize your gear, and complete Whispers in the PvP Area.
Start running Nightmare Dungeons to level your Glyphs. Always aim for +10 Monster Level to maximize experience.
When you get to Tier 46 Nightmare Dungeons, you can start running The Pit. This is recommended primarily for Solo players since split farming Nightmare Dungeons in groups will be better.
