Season 4 - LootB-Tier

Share on Social

Welcome to the Bone Spear Necromancer Leveling Guide. With a spear of bone in your hands, nothing can stand in your way! Bone Spear pierces all enemies it hits, then breaks apart when it collides with an object or the end of its travel distance, reflecting back three or five shards of Bone Shards.

This incredibly strong skill alone allows you to snipe enemies, chase and defeat Treasure Goblins, defeat bosses, and do sufficient Area of Effect (AoE) damage to demolish anything in the game, even on World Tier 2 - Veteran. Terrifyingly powerful on its own? Yes. But this build guide equips you with every utility skill and damage increase to take the Bone Spear Necromancer build to its absolute limits.

Even better, you don't need to rely on an army of useless skeletons to help you out. You quickly sacrifice these minions, while focusing all of your might on the power of Critical Strike Chance with Bone skills.

The satisfying part of this build's leveling experience is that it does not depend on any random Legendary drops! Making use of the Codex of Power Dungeons is enough to get you to the endgame, but if you find some key Aspects during your journey you can incresae your damage tremendously.

Best of all, this build transitions perfectly into the Bone Spear Endgame Necromancer. Then, your enemies will truly know the terrifying power of Bone.

Season 4 - Loot Reborn

In Season 4, the Season Theme revolves around helping out the Iron Wolves. Compared to past themes, this one does not offer any borrowed power as the entire game has been redesigned with new itemization and crafting options, increasing player power substantially across the board. Instead, you can gather reputation similar to the Vampire Bounty Board from Season 2 to unlock rewards that supercharge your leveling journey to 100 with extra items, crafting materials and eventually even a Resplendent Spark to craft an uber unique.

We recommend to follow the seasonal questline until you unlock the reputation system, check which rewards suit you most and then follow your regular leveling path. To learn more, check out our full Season 4 guide for more information.


Bone Storm

Bone Storm is an Ultimate ability providing Critical Strike Chance and Damage Reduction.

Skill Tree & Gameplay


Iron Maiden is an incredible Essence generator in high density encounters but can only generate Essence when it hits a non-cursed enemy.

Grim Harvest also generates 4 Essence every time you consume a Corpse with Raise Skeleton.

Raise Skeleton summons 3 Skeletal Mages - Cold which restore 3 Essence with their primary attack.

Bone Spear

Bone Spear always travels a fixed distance while piercing every enemy and then splits into 3 or 5 Bone Shards that return a portion of the distance travelled. It is important to hit as many enemies as possible with both portions of the Bone Spear. You can bounce your Bone Spear off a wall to limit the distance travelled, which is especially useful against Elites with the Suppressor affix.

Corpse Tendrils

Corpse Tendrils may be the best source of Crowd Control (CC) in Diablo 4. It Slows, Stuns, applies Vulnerable or generates Blood Orbs and pulls every monster (except Bosses) into a single space so that all of your AoE damage becomes infinitely more effective. With a few of your modifiers and Passives, these statuses become great sources of damage scaling as well. NOTE: Corpse Tendrils does not consume Corpses.

Bone Storm

Bone Storm mainly functions as an awesome buff that gives you 15% Damage Reduction and 20% Critical Strike Chance during its duration. You do not really care about the damage it provides.

Blood Mist

Blood Mist makes you Immune in dangerous situations but is has a long 24 second cooldown. Only use it when absolutely necessary!

Key Passive

Unlocking the Ossified Essence Key Passive massively increases your damage by making Essence over 50 a damage multiplier. From this point onwards +Maximum Essence on your gear becomes more valueable.

Book of the Dead

The Bone Spear Necromancer utilizes the Essence generation of Skeletal Mages - Cold while sacrificing the rest of the available Minions. Once you have achieved sufficient Essence sustain, sacrifice Skeletal Mages - Bone. During leveling you can choose between sacrificing Skeletal Warriors - Skirmishers and Skeletal Warriors - Defenders depending on how your Elemental Resistances look like.

Unlocking the Book of the Dead

You're able to summon Skeletons as early as level one, with the ability to customize your Skeletal Skirmishers starting at level 5, when the Book Menu unlocks. From there, you unlock more types of Skeletal Warriors, Skeletal Mages and eventually Golems as you gain levels. The Golem requires you to complete a Quest, which is detailed in this resource post. You must put the Raise Skeleton and Golem skills on your skill bar to summon them.

How To Level

In Diablo 4 you level by completing the Campaign, collecting Grim Favors for the Tree of Whispers, completing Helltide activities, grinding Dungeons, or interacting with the Seasonal mechanics. While there are many ways to level up in Diablo 4, not all of them are made equal.

Campaign Leveling

  • For your first character in Diablo 4, completing the Campaign provides the best gameplay experience and gives you access to key unlocks like your Mount.
    • If you don't have your Mount, you MUST progress the Campaign until you complete the quest Donan's Favor at the start of Act 4.
    • After obtaining your Mount you can skip the remainder of the campaign at any time.
    • The Campaign is the slowest way to level, but it's worth experiencing the Campaign and Diablo 4's storyline at least once.
    • To play Seasonal Content you need to have completed or skipped the Campaign.

Seasonal / Alt Leveling

  • Complete the Seasonal questline, progress your Seasonal Journey to unlock Legendary Aspects and work on your Seasonal powers.
  • If your account is below Rank 5 Renown in each zone, focus on completing your Renown.
    • This only needs to be done once per realm (Softcore / Hardcore).
  • Complete the Dungeons needed for any Legendary Aspects from your Codex of Power.
  • From level 1-50 you should focus on getting experience in Helltides by combining Helltide activities with Grim Favors for the Tree of Whispers or complete Gathering Legion Events.
  • After level 50 you need to balance leveling up, Glyph Experience and participating in Endgame activities like Helltide, Tree of Whispers and Bosses. The fastest experience possible after reaching World Tier 3 is completing Nightmare dungeons with monsters exactly 10 levels above your current level. Check out our Nightmare Dungeon Tier List for the best Nightmare Dungeon layouts!
  • Around level 30-45 you should move to World Tier 3.
  • Around level 50-65 you should move to World Tier 4.
  • Alternatively: Get boosted by a friend to World Tier 4 then leech experience/loot and Glyph exp (post 50), in Nightmare dungeons.
  • Find the most efficient way of leveling your character in detail in our Speed Leveling Guide.

Leveling Tips and Tricks

Let's look at some tips and tricks to remember when leveling up!

  • Level Up Your Potion. You need to farm materials to upgrade your character's potion.
    • Make sure you collect all materials as you explore Sanctuary, especially Gallowvine which is used in many Elixir recipes!
  • Compare your Items... Literally. Press Shift over an item in your inventory to compare it to what you're wearing.
    • This makes it easy to determine what is and isn't an upgrade.
  • Don't Imprint Your Best Aspect Onto Your Weapon. The most critical piece of gear while leveling up is your weapon, which gets replaced constantly.
    • It is a better idea to put your best Offensive Aspect on your Amulet, which can be used for a long time.
  • Sacred is just better. Between level 30 and 50 you're able to beat the Capstone Dungeon and enter World Tier 3, you gain access to powerful Sacred items which have higher item power and better stats. Getting a Sacred weapon significantly improves your farming speed.
    • The same happens with World Tier 4 and Ancestral gear.

Video Guide


  • The Bone Spear Necromancer specializes in single target damage, and can annihilate enemies when their back is against a wall.
  • Keep your Essence high so that Serration and Ossified Essence function at peak capacity.
  • Start off with a few Skeletons, but quickly Sacrifice them. Where we're going, we're going alone.
  • Happy blasting 🚀!
