The Bone Spear Lidless Wall build is one of the most powerful and efficient setups for Necromancer players looking to dominate in Diablo IV. Known for its high burst damage, strong crowd control, and balanced survivability, this build revolves around synergizing the Bone Spear skill with the legendary shield Lidless Wall. By carefully crafting your skills, gear, and passive synergies, this build becomes a high-end option for endgame content such as Nightmare Dungeons, Helltide events, and World Boss encounters. For players who enjoy a calculated, sharp-playstyle that punishes enemies from a distance while maintaining control of the battlefield, the Bone Spear Lidless Wall build offers both consistency and explosive potential.

Core Mechanics of the Bone Spear Build

Bone Spear is a high-damage projectile-based core skill in the Bone skill tree of the Necromancer class. It launches a piercing spear that deals damage multiple times as it travels through enemies. This makes it perfect for both single-target and AoE scenarios. The real magic of the build lies in maximizing Bone Spear’s potential through gear, aspects, and strategic enhancements especially when paired with Lidless Wall, which can significantly increase Bone Storm uptime and overall bone damage output.

Why Bone Spear?

Among the Bone skill options, Bone Spear is favored because

  • It has a straightforward and controllable aiming mechanic, making it reliable for both ranged and up-close engagements.
  • It deals massive physical damage and benefits from Vulnerable damage bonuses, which are a core theme in the build.
  • Its upgrade path allows for Bone Splinters on return, increasing total hit count and triggering additional effects.

This skill scales exceptionally well with critical strike damage, vulnerability, and Bone-related modifiers, which the Lidless Wall build enhances even further.

The Role of Lidless Wall

The legendary shield Lidless Wall is essential to this build because of its unique aspect, which grants a chance to spawn Bone Storm when hitting with Bone skills. This greatly enhances both offense and defense.

Core Lidless Wall Benefits

  • Bone Storm UptimeThe Lidless Wall aspect can grant near-constant uptime on Bone Storm, a powerful AoE skill that also increases your damage reduction.
  • Synergy with Passive SkillsSeveral passives, such as Ossified Essence and Serration, gain increased value the more you spam Bone Spear and activate Bone Storm.
  • Defensive StabilityBeing a shield, Lidless Wall adds valuable armor and survivability without sacrificing too much offensive power.

The key to maximizing Lidless Wall’s effect is hitting as many targets as possible with Bone Spear, triggering its on-hit chance repeatedly and keeping Bone Storm swirling around you throughout combat.

Playstyle and Combat Tips

The Bone Spear Lidless Wall build rewards proactive positioning and enemy manipulation. You’re not meant to rush into danger, but to control space and funnel enemies into chokepoints for maximum spear damage.

Combat Flow
