Lidless Wall is one of the strongest defensive-offensive hybrids available to a Minion Necromancer in Diablo 4. The shield's unique effect, "Bone Storm has a chance to be automatically activated when hitting an enemy," turns the skill into a recurring, free burst of AoE damage and Diablo 4 gold damage reduction. For minion-focused builds-especially those who prefer not to spam Bone Storm manually-understanding how to trigger this proc consistently is essential. The good news: Minion Necromancers are uniquely positioned to take advantage of Lidless Wall's mechanics due to their very high hit frequency, bone synergy options, and passive bonuses that interact with minion attacks.

Below is a full breakdown of how the proc works, how minion hits interact with it, and how to maximize uptime of Bone Storm throughout your leveling and endgame progression.

1. How the Lidless Wall Proc Works

Lidless Wall's signature text reads:

"Lucky Hit: Up to X% chance to automatically cast Bone Storm when hitting an enemy."

The key mechanic here is Lucky Hit. Any damage instance-basic attacks, minion strikes, DoT ticks, or skill hits-can roll a Lucky Hit check. If that check succeeds, Lidless Wall then rolls its own chance to spawn Bone Storm.

This creates a two-layer process:

Your attack or your minions' attacks trigger a Lucky Hit roll.

If successful, Lidless Wall checks its internal chance to cast Bone Storm.

The more hits you produce per second, the more chances you have for proc uptime.

2. Do Minions Trigger Lidless Wall's Bone Storm?

Yes-minion attacks do contribute Lucky Hit rolls, and as long as the skill or minion attack possesses a Lucky Hit chance, it can proc Bone Storm.

This is the central reason a Minion Necromancer works so well with Lidless Wall. Skeletal Warriors, Mages, and especially the Golem generate constant, rapid-fire Lucky Hit opportunities.

Key minions and their Lucky Hit behavior:

Skeletal Warriors (all variants): Fast hits = many rolls.

Skeletal Mages: Shadow and Bone variants have good Lucky Hit coefficients.

Golem: Slower but high-damage attacks still contribute.

Corpse Tendrils / Corpse Explosion: Not minions, but frequently used in minion builds-excellent sources of Lucky Hit procs.

If you have 10+ minions attacking simultaneously, you're generating dozens of hits per second. This dramatically increases your chance to spontaneously spawn Bone Storm.

3. Skill Setup for Maximum Bone Storm Procs

Even though minions do most of the Lucky Hit work, you can further boost proc frequency with synergistic skills.

Core Skills That Increase Proc Chance

Blight

Very high Lucky Hit frequency due to DoT ticks.

Covers a wide area, ensuring multiple enemies are contributing to proc rolls.

Bone Spear (with Lucky Hit aspects)

Piercing + high coefficient = multiple rolls per cast.

Corpse Tendrils

Massive Lucky Hit bonus.

Hits everything in the radius several times.

Corpse Explosion

If used repeatedly, generates an enormous number of hits.

You don't need to be a "Bone build" to use these; even a pure Minion Necromancer benefits from a Bone Spear or Blight button to ensure the shield procs continuously.

4. Boosting Lucky Hit for Better Bone Storm Uptime

To make Lidless Wall proc consistently, focus on:

A. Lucky Hit Chance on Gear

Affixes such as:

Lucky Hit Chance

Lucky Hit Chance to Restore Essence

Lucky Hit Chance to Slow / Daze / Vulnerable

Even minor bonuses add up with minion spam.

B. Aspects that Multiply Hits

Aspect of Frenzied Dead (minion attack speed)

Aspect of Reanimation

Aspect of Grasping Veins (massive Lucky Hit spike)

C. Shadowblight Passive

If you're using Shadow damage, the passive triggers frequent procs, adding more sources of Lucky Hit.

5. Why Bone Storm Matters for Minion Builds

Bone Storm is more than damage-it provides:

Damage Reduction, helping your minions and yourself survive spike damage.

Continuous AoE, clearing small mobs without relying solely on minions.

Corpse generation acceleration in some setups by finishing enemies faster.

Automatic Bone Storm transforms the Minion Necromancer from passive to aggressively reactive-monsters hitting you or your minions quickly get shredded.

6. Recommended Play Pattern

Engage packs with Corpse Tendrils.

Cast Blight or Bone Spear once.

Let minions swarm the pack.

Bone Storm should proc automatically within seconds, often repeatedly.

Use Bone Storm's large AoE to reposition and gather new mobs.

With high Lucky Hit and aggressive minions, you'll see near-permanent Bone Storm uptime in dense content like Helltides, Nightmare Dungeons, or Vaults.

Final Thoughts

Lidless Wall transforms Minion Necromancer gameplay by turning Bone Storm into a recurring, free defensive buff and AoE blender. Because minions constantly generate Lucky Hit rolls, they are the perfect engine to fuel Lidless Wall's proc mechanic. By combining high-frequency minion attacks with Lucky Hit gear and buy Diablo 4 gold skills like Blight or Corpse Tendrils, you can maintain Bone Storm almost continuously, making the build far safer and more explosive in all endgame content.
