Bone Spear is a Necromancer skill in Diablo III.


The skill works very similarly to its classic version: a piercing projectile that damages all enemies in a roughly 80 yards long line and 10-12 yards width, only stopping if it hits impassable terrain or solid wall.




  • Blighted Marrow: Damage type changes to Poison, and the Spear's damage is increased by 15% for each enemy Bone Spear passes through, so each target takes more damage than the previous one.
  • Teeth: a remake of the Diablo II skill, instead of a single Spear, launches razor sharp teeth in a 30 degrees wide cone that deal 300% damage as Physical to any enemy they reach. Maximum range decreases but the area of effect increases due to increased width.
  • Crystallization: Damage type changes to Cold, and each enemy hit has their attack speed reduced by 20%, while the Necromancer's attack speed is increased by 3% for 3 seconds, stacking up to 10 times.
  • Shatter: Instead of piercing, the Spear now detonates on the first enemy hit, dealing 500% damage to all enemies within 15 yards.
  • Blood Spear: Damage is increased to 650%, but each cast costs 10% of maximum Life. Visually, Spear turns into Blood Spear.

Non-rune enhancementsEdit

  • Scythe of the Cycle (Legendary Scythe): deals 350–400% additional damage while Bone Armor is active but each cast reduces the remaining duration of Bone Armor by 4 seconds.
  • Maltorius' Petrified Spike (Legendary Two-Handed Scythe): increases Bone Spear cost to 40 Essence, but it deals 550–700% additional damage.
  • Trag'Oul's Avatar Set (Set Bonus for 6 items): Blood Spear deals 3800% increased damage. Healing from skills is increased by 100%.
  • Pestilence Master's Shroud Set (Set Bonus for 4 items): each enemy hit by Bone Spear reduces the Necromancer's damage taken by 2% for 15 seconds, stacking up to 50%.
  • Pestilence Master's Shroud Set (Set Bonus for 6 items): each corpse consumed by any skill grants an Empowered Bone Spear charge that increases the damage of the next Bone Spear by 3300%, storing up to 100 charges, each cast consuming 1 charge.
  • Masquerade of Burning Carnival Set (Set Bonus for 6 items): damage increases by 10,000% for Spears cast by the Necromancer and by 30,000% for Spears cast by Simulacrums.
