This complete Diablo 4 walkthrough takes you through the entire campaign, Act by Act, so you never lose the thread of the story or miss a key objective. From rolling your first character in the snow-blasted Prologue to the final showdown with Lilith, you'll know exactly where to go, who to meet, and what to do next — plus what waits for you once the credits roll.
Diablo 4's main story is split into a Prologue and six Acts. After the Prologue, Acts I through III can be tackled in any order you like, while Acts IV, V, and VI play out in sequence to the finale. This guide follows the natural path most players take and keeps the focus on progress rather than spoilers.
What you need before you start
- A copy of Diablo 4 on PC, PlayStation, or Xbox, with the game updated to the latest patch.
- A character class in mind. Barbarian, Sorcerer, Rogue, Necromancer, Druid, and the later Spiritborn all complete the same campaign.
- A little time. A first campaign run usually takes roughly 25–35 hours depending on side content and difficulty.
- Optional: if you have already finished the story on another character, you can toggle "Skip Campaign" at creation to jump straight into the open world.
The Diablo 4 walkthrough, step by step
-
Step 1: Create your character and play the Prologue
Start by choosing your class on the character creation screen. Every class can finish the campaign, so pick the playstyle you enjoy — the Rogue is a flexible, beginner-friendly choice, while the Necromancer and Druid offer pets and shape-shifting if you prefer those. The Prologue drops you into a blizzard on the Fractured Peaks; survive the storm, reach the village of Nevesk, and you'll get your first taste of the conflict driving the whole story.
Select any of the classes, then begin the Prologue in the frozen Fractured Peaks. -
Step 2: Act I — Hunt Lilith across the Fractured Peaks
Act I takes you to Kyovashad, the fortified city that becomes your home base. Here you'll meet Lorath, a former Horadrim, and begin tracking Lilith and her followers. Make Kyovashad your hub: it has vendors, your shared stash, and access to the Waypoint network for fast travel. Work through the main quests, cleanse the corruption you encounter, and follow Lilith's trail through the snowy north before the story moves on.
Act I establishes Kyovashad as your base and sets you on Lilith's trail. -
Step 3: Acts II and III — Gather allies and build your hero
The middle of the campaign opens up two very different regions. Act II heads to the coastal woodlands of Scosglen, the home of the Druids, where you recruit allies like Donan and unlock the Tree of Whispers. Act III drives into the harsh Dry Steppes on the road toward Kehjistan. This is the stretch where your power should really take off — spend skill points every level, slot powerful Aspects earned from dungeons into your gear, and shape your build around a clear damage and survivability plan.
Scosglen and the Dry Steppes are where you gather allies and lock in your build. -
Step 4: Acts IV and V — Kehjistan and the road to Lilith
From here the campaign tightens into a straight line. You'll push through Kehjistan and the swamps of Hawezar, confronting Lilith's most dangerous allies along the way. Keep your gear current, return to town to repair and upgrade, and don't be afraid to run a side dungeon or two if a boss feels overtuned. The closing Acts steer you toward the Cathedral of Light, the gateway to the final confrontation.
The later Acts funnel you through the final regions and on to the Cathedral of Light. -
Step 5: Act VI — Defeat Lilith and unlock the endgame
Act VI is the finale: a multi-phase battle against Lilith, Daughter of Hatred. Watch your health orb, dodge her sweeping shockwaves and floating blood platforms, and burst her down between attacks. Beating her ends the campaign — and opens the part many players consider the real game. You'll unlock Paragon Boards after level 50, clear Capstone Dungeons to raise your World Tier, and start farming Nightmare Dungeons, Helltides, and the Tree of Whispers for better loot.
Beating Lilith closes the campaign and opens Diablo 4's endless endgame loop.
Tips to get through the campaign faster
- Unlock Waypoints as you go. Touching a Waypoint adds it to your fast-travel map, saving huge amounts of backtracking between quests.
- Match your World Tier to your gear. Tier I (Adventurer) is easier; Tier II (Veteran) gives more XP and loot. Drop a tier if a fight is a wall, raise it once you out-gear the content.
- Keep your skills updated. Re-check your skill tree every few levels and refund points freely — early respecs are cheap and let you fix a stalling build.
- Do Renown side activities. Discovering areas, clearing dungeons, and finishing side quests grants Renown, which rewards skill points, Potion charges, and gold across all your characters.
- Save Aspects. Aspects from the Codex of Power can be imprinted onto fresh gear, so good weapons and armor stay relevant longer.
Stuck? Common campaign problems
A story boss is too tough
Lower your World Tier from the world map menu, run a couple of dungeons to upgrade your gear, and double-check your skill tree has a clear core damage skill plus a defensive or healing option.
I can't find the next objective
Open the map and look for the glowing quest marker, then set it as your tracked quest. If the marker points across the world, use the nearest Waypoint to fast travel close to it.
I want to skip the story on an alt
When creating a new character, enable the "Skip Campaign" option (available once any character has beaten the campaign) to jump straight into the open world and endgame.
Frequently asked questions
How long is the Diablo 4 campaign?
A focused run of the main story usually takes around 25–35 hours. Adding side quests, dungeons, and Renown activities can push that well past 40 hours.
Can you play the Diablo 4 acts in any order?
After the Prologue and Act I, Acts II and III can be done in either order. Acts IV, V, and VI then play out in sequence to the finale.
Which class is best for a first walkthrough?
Any class can finish the campaign. The Rogue and Sorcerer are popular, flexible picks for newcomers, while the Necromancer's minions make survival easier if you prefer a hands-off style.
What happens after you beat Lilith?
Defeating Lilith ends the campaign and unlocks the endgame: Paragon Boards, Capstone Dungeons, higher World Tiers, Nightmare Dungeons, Helltides, and seasonal content that keeps the loot grind going.
Do I have to replay the campaign every season?
No. Once any character has completed the campaign, you can skip it on new characters and jump straight into seasonal and endgame activities.
Final thoughts
That's the full path through Diablo 4, from your first steps in the blizzard to the fall of Lilith and the wide-open endgame beyond. Take the Acts at your own pace, keep your build and gear current, and lean on Waypoints and Renown to smooth out the journey.
