Density is a specialized mace enchantment in Minecraft that dramatically amplifies smash attack damage based on fall distance, making it essential for maximizing the mace's unique high-altitude combat potential. This gravity-powered enchantment adds 0.5 damage per block fallen per level, transforming aerial attacks into devastating ground strikes.

At maximum level V, Density adds 2.5 damage per block fallen, enabling massive damage output from elevated positions or elytra-assisted attacks. Combined with the mace's inherent fall damage mechanics, this enchantment can produce some of the highest single-hit damage values in the game when executed from significant heights.

Players can obtain Density through enchanting tables for maces, librarian villager trades for enchanted books, fishing, and ominous vaults along with other structure loot sources. However, Density is incompatible with traditional damage enchantments including Breach, Sharpness, Smite, and Bane of Arthropods, requiring players to choose between consistent damage boosts or specialized aerial combat advantages for optimal mace configuration.
