Diablo IV Beginner's Guide: Classes, Skill Tree, the Codex and Difficulty

Diablo® IV 🎮 Game page →

1. Choose your realm When creating a character, choose the Seasonal or Eternal Realm. If it's your first time, learning the story at your own pace on the Eternal Realm is a good start; seasonal rewards and leaderboards live on the Seasonal Realm.
2. Choose your class The base game has Barbarian, Druid, Necromancer, Rogue and Sorcerer. Spiritborn comes with Vessel of Hatred, Paladin and Warlock with Lord of Hatred. For a first character, Barbarian is a straightforward melee pick, Sorcerer or Rogue for ranged play.
3. Pick your campaign starting point According to Blizzard, a new character can enter the story from the base game, from Vessel of Hatred or from the recommended Lord of Hatred start. Once you've completed the story on one character, others can skip the campaign and go straight to the endgame; skipping is permanent for that character.
4. Start on a comfortable difficulty Play the campaign on a low difficulty to learn the mechanics. Raise difficulty as your character gets stronger; higher difficulty means more gold, experience and better loot. The top Torment tiers now go up to 12.
5. Get to know the skill tree The 3.0 update removed passive nodes from the skill tree; points go directly into active skills. Each active skill has three branches that open as you level, and some variants can change a skill's type, for example from Fire to Frost. Early on, focus on one main damage skill and one escape or defensive skill.
6. Unlock waypoints Activate waypoints in towns; you can fast-travel to them from the map. The Town Portal on T also gives a quick return to empty your inventory and restock potions.
7. Get your mount As you progress through the story, the quest A Trusty Steed becomes available and grants your mount. Summon it with Z and spur with Space; it cuts open-world travel time dramatically.
8. Clear dungeons for the first time The first clear of many dungeons adds a Legendary Aspect to your Codex of Power. You imprint Codex aspects onto gear to power up, so don't ignore dungeon icons on the map.
9. Set up the Loot Filter As you level, lots of items drop. The Loot Filter under Options > Gameplay lets you hide gear you don't want and colour-code what you're looking for.

• Make Evade a reflexEvade on Space is the main way to escape big hits and ground effects. Use it the moment you see a boss wind-up, not only when your health is low.
• Don't waste potionsPotions are limited. Health orbs and towns refill them; try to enter tough fights with full charges.
• Attack in placeHolding Shift while clicking makes your character attack from where it stands without walking. For ranged classes this stops you accidentally walking into enemy packs.
• Check the Codex regularlyWhen you find a higher roll of a Legendary Aspect, its Codex of Power entry is upgraded. When upgrading gear, check the Codex for the strongest value you can imprint.
• Read item comparisonsHovering over a new item shows a comparison with your current gear. Look beyond the Item Power number to the affixes that support your skills.
• Join world eventsOpen-world events are completed quickly with other players and reward experience and loot. Regional events like Helltide become an important material source at higher levels.
• Don't fear respeccingYou can reallocate skill points. When you find a new unique item or a strong aspect, adjusting your tree around it often makes a big difference.
• Try the Map OverlayThe Map Overlay added in 3.0 places a semi-transparent map over the screen. Adjust zoom and opacity under Options > Gameplay and bind shortcuts under Options > Controls.
• Consider playing in a partyGrouping with friends clears dungeons and events faster. In the endgame, Lord of Hatred's War Plans system organises progression by chaining activities you choose.
• Bind keys to suit youMany actions are unbound by default. Assign keys to what you use often under Options > Controls; the game also recognises extra mouse buttons.

• Building your skill tree from guides written before April 2026: the 3.0 update removed passive nodes, so old allocations no longer fit.
• Confirming the campaign skip without thinking: skipping is permanent for that character.
• Raising difficulty far above your character's power: deaths waste time and slow progress.
• Skipping dungeons entirely: your Codex of Power stays thin and your character struggles to grow.
• Picking up every item and filling your inventory: without a Loot Filter, managing loot at high levels eats time.
