Summon a piercing bone projectile that causes 500% damage as Physical to all enemies it passes through.

Damage Type: Physical

Bone Spear is a Necromancer skill in Diablo III.

In-game[]

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.

Runes[]

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.
