The Necromancer Bone Spear build remains the S-tier boss killer in Season 6 thanks to a fundamental rework of the Bone Spear aspect and the addition of “Bone Storm” as a baseline skill. This guide covers gear, skills, paragon board, and rotation.
Skill Build (Leveling & Endgame)
| Slot | Skill | Runes / Notes |
|---|---|---|
| Basic | Bone Splinters | Fuel for essence generation. |
| Core | Bone Spear | Primary damage — cast on cooldown. |
| Core | Bone Storm | Ultimate defensive + burst. |
| Corpse | Decompose | Auto-summon corpses. |
| Cursed | Iron Maiden | +40% damage taken debuff. |
| Corpse & Macabre | Raise Skeleton | Adds warriors passively. |
| Ultimate | Army of the Dead | 4-second invuln + burst window. |
Gear Priority
- Ring of Starless Skies — reduces resource cost; mandatory.
- Aspect of the Umbral — on amulet; +1 Bone Spear per cast.
- Twin Strikes — gloves; doubles Bone Spear crit chance.
- Shattered Vows — ring #2; +25% vulnerable damage.
Paragon Board Route
Start with the Bone Graft board, then route into Wither for essence refund, and finally spend the remaining points in Cult Leader for crit damage scaling. Save 50 paragon points for the seasonal Withering Cage glyph socket.
Rotation
- Pre-cast Decompose to spawn corpses.
- Apply Iron Maiden to the boss.
- Channel Bone Spear for 4 seconds.
- Activate Army of the Dead during cooldown windows.
- Use Bone Storm defensively when HP drops below 60%.
Tier Placement
S-tier for bossing. A-tier for mapping (Ice Shards outpaces it on density). This build single-target kills Tormented Lilith in under 12 seconds with average gear.
