Equipment

Vengeful Sinew is the first Unique to pursue. Its second explosion is particularly valuable against Elites that survive the opening Bone Spirit, and the bonus to Bone Spirit damage benefits every cast. The chest piece also offers Ranks to Bone Spirit, making it an excellent target for a Greater Affix. Until you find it, the character can function with regular Bone Skills, but its signature damage pattern depends on this item.

Lidless Wall gives Bone Storm much better coverage. With an active storm, your attacks can create new storms around enemies, and each active storm increases Critical Strike Damage. Aspect of Rapid Ossification on Ring 1 helps Bone Storm return sooner as you spend Essence. The pairing is especially useful when moving through several Elite groups in quick succession. Keep a one-handed weapon in the Main Hand so the Shield remains equipped.

The build uses a mixture of offense and Resolve-based defense. Aspect of Glynn's Anvil belongs on a Legendary Helm, Aspect of Interdiction on Boots, and Aspect of Redirected Force on the Amulet. Commanding Skeleton Warriors grants Resolve, while Cold Skeleton Mages can add more stacks as they attack. These aspects turn the resulting Block Chance into both survivability and Critical Strike Damage. It is an effective way to stay close enough for Bone Storm without making the character excessively fragile.

Blood Moon Breeches provide additional defense against Cursed enemies. Skeleton attacks can apply Decrepify or Iron Maiden automatically, making the pants particularly useful during long fights. They work alongside the Minions you already need for Essence and Resolve. Aspect of Bursting Bones on Gloves and Splintering Aspect on your one-handed weapon then bring the focus back to Bone Spirit: the first rewards Maximum Essence and the second rewards Vulnerable targets.

For the final damage slot, Aspect of Compound Fracture on Ring 2 benefits from the many Bone Skill Critical Strikes generated by Bone Spirit, its smaller spirits and Bone Storm. Art of the Bone Weaver is the preferred Talisman set, with Gravewalker's Hand in the sixth Charm slot to improve Essence Generation and Bone Skill damage. Leoric's Crown is an optional Helm for players who prefer stronger gem effects and Attack Speed; it replaces Glynn's Anvil and sacrifices part of the Resolve-based protection.

The following Legendary Aspects are arranged for the main one-handed weapon and Shield setup. Each has a free Legendary slot: Glynn's Anvil on Helm, Bursting Bones on Gloves, Interdiction on Boots, Redirected Force on Amulet, Rapid Ossification on Ring 1, Compound Fracture on Ring 2 and Splintering on Main Hand. Vengeful Sinew, Blood Moon Breeches and Lidless Wall occupy the remaining armor and Off-Hand slots.

Prioritize Maximum Essence, Essence Regeneration, Ranks to Bone Spirit, Critical Strike Chance and Critical Strike Damage on Legendary equipment. Intelligence and Vulnerable Damage further improve the main attack, while Maximum Life, Armor and Resistance to All Elements provide the defensive foundation. The Mages supply a large share of Essence Regeneration, so their uptime matters as much as your equipment rolls. Greater Affixes on Ranks to Bone Spirit and the Shield's Critical Strike Chance are excellent upgrades.

Skills

15/15

Bone Spirit

Primary DPS: Bone Spirit seeks out enemies and bursts on impact. With Vengeful Sinew, every cast produces another explosion, and Poltergeists sends smaller spirits after survivors. Casting into a tightly grouped pack is particularly effective because the follow-up damage has more targets to find.

Max out the skill and select Maximum Essence, Core Skill and Poltergeists. Core Skill turns it into an Essence-spending attack without a Cooldown and increases damage according to Essence consumed. Cast when your resource pool is full or close to full.

15/15

Bone Storm

Utility/Offence: Bone Storm keeps damaging nearby enemies while you line up Bone Spirit. Lidless Wall can spread additional storms through the battlefield, raising your Critical Strike Damage and giving you more consistent coverage against groups.

Choose Roll The Bones, Duration Increase and Barrier. These improve Critical Strike Chance, extend the storm by consuming Corpses and provide a strong defensive Barrier. Keep Bone Storm active whenever a dangerous fight is underway.

1/15

Corpse Tendrils

Utility/Control: Corpse Tendrils gathers scattered enemies into a compact group, giving Bone Spirit an easy target for both its initial impact and the smaller Poltergeists. It also creates a safer moment to approach the pack with Bone Storm active.

Select Essence Generation, Get Over Here! and Vulnerable. Get Over Here! lets you cast Tendrils around yourself and Fortifies you for enemies hit. The Essence gain prepares your next Bone Spirit, while Vulnerable strengthens Splintering Aspect.

1/15

Skeleton Warrior

Utility/Def: Skeleton Warriors keep enemies busy and provide the most reliable way to build Resolve. Activating their command gives you an immediate source of Resolve stacks, enabling the Block Chance from Interdiction and additional defenses from Glynn's Anvil.

Take Healing, Master of Puppets and Resolve. Command the Warriors regularly against Elites and Bosses to refresh Resolve. Their attacks also have a chance to apply the Curses granted by Blood Moon Breeches.

15/15

Skeleton Mage

Utility/Resource: Cold Skeleton Mages are the engine behind your repeated Bone Spirit casts. Gift of Death provides Essence Regeneration for every active Mage, and their attacks can also grant Resolve. Keeping them alive lets you build Essence for the next heavy explosion.

Use Critical Strike Chance, Gift of Death and Ferocity, Resolve, or Overpower, with Cold Mages chosen in the Book of the Dead. Gift of Death requires Corpses to summon Mages; refresh them as new Corpses become available.

1/15

Sever

Utility/Mobility: Sever gives a traditionally slow Necromancer a much faster way to travel. The Inexorable Reaper variant carries you forward with the attack, making it easy to close the gap after a Bone Spirit explosion or leave a dangerous area.

Choose Cost Reduction, Inexorable Reaper and Crowd Control and Corpse Generation. The last upgrade creates Corpses for Skeleton Mages even during Boss encounters, helping your Essence recovery continue when few enemies are dying.

1/15

Iron Maiden

Triggered Curse: Iron Maiden is part of the defensive package supplied by Blood Moon Breeches. Summon attacks can inflict it on enemies automatically, and the resulting Curse helps reduce incoming damage through the pants.

Allocate points into Iron Maiden and useful defensive upgrades when available. It does not need one of your six Skill Bar slots for the Blood Moon Breeches effect to apply. The same item also allows Summons to apply Decrepify.

1/15

Blood Mist

Optional Defense: Blood Mist offers a safer option for difficult Boss encounters. It provides immunity during dangerous attacks and gives you a way to survive when Bone Storm and Resolve stacks are temporarily unavailable.

Choose its defensive and recovery upgrades. Replace Sever with Blood Mist when you need more protection, accepting slower movement and less convenient Corpse generation during Boss fights.

Core Rotation

Start by keeping Skeleton Warriors and Cold Skeleton Mages active. Command the Warriors to gain Resolve, then cast Bone Storm before approaching a difficult pack. Pull enemies together with Corpse Tendrils and wait for your Essence to recover. Once your pool is full, release Bone Spirit into the group. The two explosions from Vengeful Sinew and the Poltergeists that follow can clear several enemies before the first target even falls.

During longer fights, rebuild Essence through Gift of Death Mages and Corpse Tendrils. Use Sever to change position and create a Corpse when the battlefield runs dry. Refresh your Warriors' command for Resolve and use Bone Spirit often enough to maintain Quintessence from Art of the Bone Weaver. Against Bosses, keep Bone Storm running for its Critical Strike benefits, then land Bone Spirit after Vulnerable is applied. If the fight is too dangerous for aggressive positioning, use the Blood Mist variant for an emergency escape.

Miscellaneous

Paragon Board

Open with Bone Graft, which strengthens Bone Skills and Maximum Essence. Both matter immediately: a larger Essence pool increases the damage of Core Skill Bone Spirit and strengthens Aspect of Bursting Bones. Follow with Flesh-eater for extra damage after consuming Corpses, then Scent of Death for improved damage and defenses when fighting in crowded areas.

Frailty is a valuable later board for more damage against weakened targets, while Bloodbath is useful when your gear and bonuses consistently support Overpower. Prioritize efficient Legendary Nodes and Glyph sockets before investing in distant secondary clusters. The strongest route takes Maximum Essence, Intelligence, Maximum Life and defensive nodes needed to keep you alive near Bone Storm targets.

For Glyphs, use Essence, Gravekeeper, Eliminator, Amplify and Corporeal. Essence is the first priority for the main damage engine. Gravekeeper and Amplify reward active Corpse use and Curses, while Eliminator and Corporeal complete the critical damage and survivability package. Meet each Glyph's required attribute threshold with the nearby Paragon nodes.

Book of the Dead

Use Cold Skeleton Mages with the Resolve-generating upgrade and active Skeleton Warriors with the Resolve command. The Mages maintain your Essence Regeneration through Gift of Death, while the Warriors provide on-demand Resolve and help apply the Curses from Blood Moon Breeches. Sacrifice the Iron Golem for its Critical Strike Damage bonus. This setup keeps the defensive aspects working even during Boss encounters.

Runes

Cir + Que grants an Earthen Bulwark Barrier after repeated Skill casts. It is particularly useful when your Bone Storm Barrier expires between large encounters. For additional damage, use Tam + Ohm: Bone Spirit counts as a non-Channeled Core Skill, generating Offering for the Barbarian War Cry invocation. Use one valid two-socket item for each Runeword pair.

Talisman

Art of the Bone Weaver is the preferred set. Spending Essence on Bone Skills grants Quintessence, improving Critical Strike Chance and Critical Strike Damage. The three-piece bonus adds Damage Reduction, and the full set releases bone shards that generate Essence and make affected enemies take substantially more Bone Skill damage. Try to keep Quintessence active through regular Bone Spirit casts.

Complete the five-piece set with Berú, Fer, Linta, Mlor and Phoba of the Bone Weaver. Use Gravewalker's Hand as the sixth Charm for extra Essence Generation and Bone Skill damage. On individual Charms, favor Ranks to Bone Skills, Maximum Essence, Intelligence and valuable defensive bonuses.

Mercenary

Use Raheir as your hired Mercenary with Shield Charge, Raheir's Guard, Provoke and Mocking Lure. His protection helps while you remain close enough for Bone Storm and Skeleton Warrior commands. Choose Aldkin as Reinforcement with Field of Languish, triggered when you cast a Skill, for additional control during crowded fights.

Final Thoughts

The Bone Spirit Necromancer rewards careful Essence management with explosive damage that can wipe out entire packs. Vengeful Sinew, Bone Storm and a reliable Minion setup give the character both power and the defenses needed to survive close-range encounters.
