What is Horde Of Mobs?
If you enjoy chaotic battles and overwhelming hordes, you'll love this addon!
When a mob spawns naturally, it has a chance of cloning itself, and even a small chance of creating a second clone. This means more than two mobs can appear from a single spawn!
You'll need to fight carefully, as cloned mobs can quickly overwhelm you when you least expect it, turning a simple encounter into a real challenge!
Even monsters added by other addons will have the possibility of cloning when they spawn near a player!
✨ Key Features
- Native slash commands (
/hordeofmobs:help,/hordeofmobs:config,/hordeofmobs:reset, etc.) that work without enabling cheats - Fully customizable clone probabilities from 1% to 50%
- Two clone types: First Clone and Second Clone with independent probability control
- Five distinct mob categories: Monster, Raid, Boss, Animal and Creature, each toggleable independently
- Radius-based cloning system: Normal mobs require players to be close (4-42 blocks), while Raid mobs have an extended radius (172 blocks)
- Limit control system to prevent excessive entity saturation (
/hordeofmobs:maxpertype <1-150>) - Blacklist system to exclude specific mobs from cloning (slimes and magma cubes excluded by default)
- Custom boss system allowing any mob ID to be treated as a boss (100% clone rate)
- Multilanguage interface supporting English and Spanish, with per-player language persistence
⚙️ How It Works?
When a mob spawns naturally, the addon checks if it belongs to an enabled category (Monster, Raid, Boss, Animal or Creature). It also verifies that the mob is not on the blacklist. If the conditions are met, the system rolls for a First Clone based on the configured probability. If the First Clone succeeds, it then rolls for a Second Clone. Clones appear at the exact same position as the original mob, creating an instant horde!
Radius System:
- Normal mobs (Monster, Boss, Animal, Creature): Must spawn within 4-42 blocks of the nearest player
- Raid mobs (Illager, Ravager, Witch): Can spawn up to 172 blocks away (extended radius for invasion-style gameplay)
Limit System:
The /hordeofmobs:maxpertype <1-150> command controls the maximum number of clones allowed per mob type within the spawn radius. Default is 30.
Blacklist Priority:
- The blacklist has MAXIMUM PRIORITY. Any mob added to the blacklist will NEVER clone, regardless of other settings.
Boss System:
- Bosses (Wither, Ender Dragon, Warden and custom added bosses) clone at 100% rate
- The
/hordeofmobs:bossclones <0-10>command controls how many clones a boss creates (0 = disabled, 1-10 = number of clones)
