What Does Density Do in Minecraft? (Mace Enchantment Explained)

Current as of Minecraft Bedrock v26.1 and Java Edition 26.1 — Updated April 2026

TL;DR

• Density is a mace-exclusive enchantment that adds +0.5 damage per block fallen per level
• At max level (Density V), you gain +2.5 damage for every block you fall before landing a hit
• It only activates on a smash attack — you must hit while falling, not on flat ground
• A successful hit cancels your fall damage entirely
• It is incompatible with Breach, Smite, and Bane of Arthropods
• Best used with vertical movement — wind charges, elytra, ledges, or natural height

What Does Density Do in Minecraft?

Density is a mace enchantment that increases how much bonus damage your mace deals during a smash attack, based on how many blocks you fell before hitting your target.

The higher you fall, the harder you hit. Density makes that fall-to-damage multiplier even bigger at every level.

It was introduced in the 1.21 Tricky Trials update alongside the mace itself. It is exclusive to the mace — you cannot put it on a sword, axe, or any other weapon.

How Does Density Work?

The mace already has a built-in smash attack mechanic. When you fall more than 2 blocks and hit a mob or player before landing, you deal bonus damage based on your fall distance. A successful smash attack also knocks back nearby enemies in a small radius and cancels your fall damage entirely.

Density amplifies this fall-based bonus damage. The formula is simple:

Extra damage = 0.5 × Density level × blocks fallen

So at Density V (the maximum), every block you fall adds 2.5 extra damage to that smash attack. This stacks on top of the mace’s base damage of 6.

One important rule: if you touch the ground before landing the hit, the bonus is gone and you take fall damage as normal. You have to connect the swing during the fall.

Density Damage by Level

Here’s how much bonus damage each Density level adds per block fallen:

To put this into practice with real numbers:

Density III, 6-block fall: Extra damage = 0.5 × 3 × 6 = +9 damage Total = 6 base + 9 = 15 damage (before armor)

Density V, 10-block fall: Extra damage = 0.5 × 5 × 10 = +25 damage Total = 6 base + 25 = 31 damage (before armor)

Density V, 20-block fall: Extra damage = 0.5 × 5 × 20 = +50 damage Total = 6 base + 50 = 56 damage (before armor)

At very high altitudes with Density V, a single smash attack can one-shot nearly anything in the game — including the Warden, which has 250 hearts of health. The damage has no hard cap, so the higher the fall, the higher the potential output.

What Is the Mace?

Before Density can do anything, you need a mace. The mace is a weapon added in the 1.21 Tricky Trials update. It has a base damage of 6 and an attack speed of 0.6 — it swings slowly, but its smash attack mechanic makes it situationally the strongest weapon in the game.

The mace’s base smash attack damage already scales with fall distance, even without Density. Density just makes each block of fall count for even more.

How to Craft the Mace

To craft a mace you need 1 Heavy Core and 1 Breeze Rod. Place the Heavy Core above the Breeze Rod in any crafting grid — you don’t even need a crafting table, your inventory grid works fine.

Neither item is easy to get:

Breeze Rod — dropped by the Breeze mob, which spawns inside Trial Chambers. Every Breeze has a 100% chance to drop 1–2 rods. You only need one rod to craft the mace.

Heavy Core — only obtainable from Ominous Vaults inside Trial Chambers. These vaults need an Ominous Trial Key to open. To get that key, you need to complete an Ominous Trial — which requires drinking an Ominous Bottle near a Trial Chamber to gain the Bad Omen effect, making the spawners turn ominous, and then defeating them. Even then, the Heavy Core only has roughly an 8.3% chance to drop from an Ominous Vault, so you may need to run multiple Trial Chambers before you get one.

The mace is a true late-game reward. The effort to obtain it is part of the payoff.

How to Get the Density Enchantment

There are four main ways to get Density:

Enchanting Table — place your mace directly on the enchanting table. Surround it with 15 bookshelves to reach level 30 enchantments and get the best chance at higher Density levels. If Density doesn’t appear in the offered options, enchant a cheap throwaway item in the lowest slot to reset the enchantment pool, then check again.

Enchanted Books from Structures — Trial Chambers are the best source. The Ominous Vaults in particular have a strong chance of containing high-level Density books (IV and V). Dungeons, Nether bastions, and temples can also contain Density books, though the odds are lower.

Librarian Villagers — find a village with a librarian and trade with them. Librarians at any level can offer Density books. If their stock doesn’t have it, break and replace their lectern to reset their trades until you get the one you want.

Fishing — enchanted books with Density can occasionally appear as fishing loot, though this is the slowest and least reliable method.

Once you have a Density book, use an anvil to apply it to your mace. Our Minecraft enchanting table guide covers the full process for setting up an enchanting area and applying books efficiently.

Density vs Breach: Which Should You Choose?

These two are the main competing mace enchantments and they cannot go on the same mace together. You have to pick one.

Density scales with fall distance. The more blocks you fall, the more damage you deal. It rewards vertical movement and aerial attacks. It works brilliantly when you have height — wind charges, elytra drops, high terrain, Trial Chamber corridors with elevated platforms.

Breach ignores a percentage of your target’s armor. At Breach IV, it bypasses 75% of armor reduction. This makes it consistently strong against heavily armored players in PvP, where you’re fighting on flat ground and can’t rely on fall distance.

Here’s the simple decision guide:

For most survival players who mainly fight mobs and bosses, Density V is the better pick. It delivers higher burst damage in those scenarios, especially with any vertical setup at all. If you’re focused on PvP, Breach gives you more consistent output against armored opponents.

Enchantments That Work With Density

Density is incompatible with Breach, Smite, and Bane of Arthropods. You can only have one of these four on a mace at a time.

Everything else is fair game. Here are the enchantments that pair well with Density:

Wind Burst — after a successful smash attack, this launches you upward into the air. This lets you chain smash attacks back-to-back without needing external height. You land a smash, get launched up, fall again, land another smash. It’s one of the most powerful combat loops in the game when paired with Density.

Mending — repairs your mace using XP orbs you pick up. Since the mace is hard to craft again (needing another Heavy Core), Mending is strongly recommended to protect your investment.

Unbreaking — increases the mace’s durability, reducing how fast it degrades. Works well alongside Mending.

Fire Aspect — sets targets on fire on hit, adding damage over time after the smash lands.

A fully optimised PvE mace build looks like this: Density V + Wind Burst III + Mending + Unbreaking III. This gives you maximum burst damage, infinite aerial chaining, and sustainable durability without constantly needing repairs.

Best Situations for Density

Trial Chambers — the corridors and multi-level rooms give you constant opportunities to drop down on enemies from platforms above. Density was practically designed for this environment.

Boss fights — the Ender Dragon, Wither, and Warden all have massive health pools. A Density V smash from significant height can one-shot even the Warden, which has one of the highest HP values in the game. For taking on the Ender Dragon, check our guide on how to defeat the Ender Dragon in Minecraft — a high-altitude mace build is one of the strongest options for that fight.

Wind Charge setups — fire a wind charge at the ground to launch yourself upward, then swing down during the fall. This works on flat terrain and essentially lets you create your own fall height anywhere.

Elytra dives — dive from height with an elytra, then transition into a free fall and connect the smash. Extremely high fall distances are possible this way, pushing Density damage into absurd numbers.

Natural terrain — mountains, cliffs, floating island bases, and high cave ceilings all give you free height to work with. You don’t need elaborate setups if you fight smart.

If you’re building a floating island base — a naturally great spot for Density combat — our guide on how to build a floating island base in Minecraft has some solid ideas.

Density in PvP

Density works in PvP too, but it requires timing and positioning that’s much harder against real players than mobs. Players can dodge, sprint away, or return fire during your fall window. Missing the hit means you take full fall damage, which can end a fight instantly.

That said, a well-timed Density smash in PvP is devastating. Players with Wind Burst can chain aerial attacks and keep the pressure going. Wind charges for self-launch add an element of surprise. If you’re skilled with vertical movement and play aggressively, Density is absolutely viable.

For casual PvP or players who aren’t comfortable with the aerial timing, Breach is the safer pick because it deals reliable damage without depending on setup.

Common Mistakes With Density

Landing before hitting. The smash only activates while you’re still falling. If you hit the ground first, you take full fall damage and deal no bonus smash damage. Practice timing the swing slightly early — the hit registers mid-air.

Using it on flat ground. Density adds zero bonus damage if you haven’t fallen at all. On flat terrain, you’re basically using a slow weapon with no enchantment benefit. Always set up height before engaging.

Skipping Feather Falling. While Feather Falling doesn’t affect your smash damage bonus, it saves your life if you miss. Keep Feather Falling IV on your boots while practicing smash attacks — it’s a safety net that pays for itself immediately.

Not using Wind Burst. Density alone requires constantly finding new height before each attack. Wind Burst removes that limitation by bouncing you back up after each hit, enabling a continuous chain. The two enchantments are designed to work together.

Wasting the mace on regular hits. At attack speed 0.6, the mace swings slowly. Using it for regular flat-ground attacks instead of saving it for smash setups is inefficient. Keep a sword for standard combat and pull out the mace when you have height advantage.

Repairing Your Mace

Since getting a second Heavy Core to craft another mace is a real grind, keep your mace repaired. You have three options:

Mending enchantment — the best long-term solution. XP orbs automatically repair the mace as you collect them. Pair with an XP farm for the easiest upkeep. See our guide on how to make an XP mob farm for efficient XP generation.

Breeze Rods in an anvil — place your mace and a Breeze Rod in an anvil. One rod restores roughly 25% durability. It costs XP levels but works well mid-game.

Combining two maces — put two damaged maces in a grindstone or crafting grid to merge their durability with a 5% bonus. Note that using a grindstone for this strips all enchantments, so use an anvil if you want to keep them. Our grindstone guide explains exactly when to use each repair method.

Quick Reference: Density Summary

Wrapping Up

Density is one of the most exciting enchantments Minecraft has ever added. It rewards movement, positioning, and timing rather than just stat grinding. The higher you fall, the harder you hit — and a successful hit cancels your fall damage entirely, making the whole loop feel satisfying to pull off.

For PvE players and boss hunters, Density V is essentially the best damage enchantment in the game when you have any vertical space to work with. Pair it with Wind Burst and Mending, practise the smash timing, and you’ll clear content that used to feel impossible.

Start by getting your mace from the Trial Chambers, then build toward Density V through the enchanting table or Ominous Vault loot. Once it clicks, every fight becomes a game of finding the right angle — and dropping the hammer.
