Diablo 4 Season 1 Bone Prison Necromancer Build



In dungeons with multiple enemies, activate Bone Storm and Blood Mist simultaneously to deal massive area damage. Use Bone Prison to keep enemies together and spam Corpse Explosions for additional damage. Rinse and repeat to maintain near-constant Blood Mist uptime.

For boss fights, place Bone Prison before activating Bone Storm and Blood Mist. Build up critical hits to unleash a massive explosion from the Barber heart. If necessary, repeat the process until the boss is defeated.
