About this Mod

Unholy Mobs randomly empowers spawning hostile mobs with powerful variant types, making them significantly tougher.


The mod currently introduces four variants of special mobs:

Variant Default spawn chance
Insane ~1%
Extreme ~0.2%
Grandpa ~0.04%
Silent ~0.008%
  1. Each higher tier includes all strengths of the previous ones and adds more on top. Power grows roughly exponentially between tiers.
  2. Empowered mobs gain an particle aura effect and prefix to its name. Making them distinguishable from normal ones.

Enhanced mobs receive:

  • Increased health, damage, and movement speed
  • Regeneration, resistance and knockback resistance
  • On-hit debuffs applied to the player, such as Slowness, Weakness, Poison, Blindness, Wither or Nausea
  • Special behaviour for the strongest variants, like teleportation, periods of invisibility or sound reduction

Improved loot for defeating Unholy mobs:

  • Significantly more experience
  • Extra items (ores, resources, rare materials)
  • Enchanted books with low to high-level enchantments
  • Special Variant Cores

Random events:

Silent Night:

At the begining of night when the moon rises (12990 - 13000 in-game time), there is a chance (~0,1% default) for the night to be "Silent" - if this happens, spawn rates of the silent mob variant are increased 400x times, event ends with the sunrise (22990 - 23000 in-game time).


Unholy Night:

At the begining of night when the moon rises (12990 - 13000 in-game time), there is a chance (~1% default) for the night to be "Unholy" - if this happens, spawn rates for unholy mobs are increased 10x times for each variant, event ends with the sunrise (22990 - 23000 in-game time).


Configuration & Commands:

Unholy Mobs allows you to adjust Unholy Mobs spawn rates and chances for random events:

Using "/unholy_spawn_chance" command you can set/get/multiply the spawn chances of each variant:

  • /unholy_spawn_chance <variant> set <percent> percent - sets the spawn chance to provided percentage.
  • /unholy_spawn_chance <variant> multiply_times <multiplier>  - multiplies current spawn chance for variant.
  • /unholy_spawn_chance <variant> get - shows you current spawn chance of variant.

E.g.:

  • /unholy_spawn_chance Insane set 4 percent
  • /unholy_spawn_chance Extreme multiply_times 6
  • /unholy_spawn_chance Silent get

Similarly using "/unholy_event_chance" command you can set/get/multiply the chance for specific event:

Note that lower variants take priority when spawning. This means that if the chances are set to 100% for both Insane and Extreme, the mob will attempt to become Insane first, in this case causing its variant to always be set to Insane.


Items & Recipes:

Variant Cores and Swords:

  • - Insane Core, Netherite Insanity Breaker
  • - Extreme Core, Netherite Extremeness Blade
  • - Grandpa Core, Netherite Elder Madness
  • - Silent Core, Netherite Hushed Blade

Sword and Core Recipes:


"Unholy Mobs" is intended for players who want standard Minecraft combat to be more challenging and less predictable, especially in hardcore or harder difficulty settings.
