Description

🧟‍♂️ Undead Riders

Undead Riders is a Fabric mod for Minecraft that adds naturally spawning undead horsemen to the overworld surface.

Six types in total, each tied to a fitting biome. Fully configurable and difficulty-scaled.

 

✨ Features

  • 🐴 Zombie Horseman — Zombie on a Zombie Horse. All biomes except Desert. Night only.
  • 🏜️ Husk Horseman — Husk on a Zombie Horse. Desert only. Night only.
  • 💀 Skeleton Horseman — Skeleton on a Skeleton Horse. All biomes except Desert/Swamp/Frozen. Night only.
  • ☀️ Parched Horseman — Parched on a Skeleton Horse. Desert only. Day and night.
  • 🌿 Bogged Horseman — Bogged on a Skeleton Horse. Swamp and Mangrove Swamp only. Night only.
  • ❄️ Stray Horseman — Stray on a Skeleton Horse. All frozen biomes. Night only.
  • 🐗 Zombified Piglin Rider — Zombified Piglin on a Zoglin. Crimson Forest, Nether Wastes, and Bastion Remnants.
  • 💀 Nether Skeleton Horseman — Skeleton on a Skeleton Horse. Soul Sand Valley only.
  • 🎁 Saddle drop — Horses only spawn with a saddle at a low configurable rate (default 15% zombie, 10% skeleton). Saddles are looting-aware: Looting III gives ~20% drop chance. Players must hunt at night for saddled horses!
  • 🔥 Optional Skeleton Horse sunlight burn — Skeleton Horses can be configured to burn in sunlight. A separate option can make saddled Skeleton Horses protected from that sunlight burn. Vanilla Skeleton Horse traps and their triggered horsemen are always excluded.
  • 🛡️ Horse armor — ZombieHorses have a configurable chance to wear armor (default 60%). 40% spawn without.
  • 🔑 Tameable Skeleton Horses — After killing the rider, Skeleton Horses can immediately be saddled and ridden.
  • 🛡️ Shield on Hard — Zombie and Husk riders have a 40% chance to carry a shield.
  • 🏹 Enchanted bow on Hard — Skeleton, Parched and Stray riders have a 30% chance for a Power I–III bow.
  • ⚠️ Unarmed on Easy — Zombie and Husk riders have a 25% chance to spawn without a weapon.
  • ⚔️ Difficulty-scaled weapons — Zombie/Husk riders carry tier-appropriate weapons including 1.21.11 Spears.
  • 🔀 Independent toggles — Each type can be enabled/disabled separately.
  • ⚙️ Fully configurable — Spawn rates, saddle/armor chances, distances, timing, and more.
  • 🧭 Optional Open Parties and Claims support — When OPAC is installed, Undead Riders respects claimed chunks where hostile natural spawning is disabled.
  • 🖥️ Optional Mod Menu support — On clients with Mod Menu and Cloth Config installed, the config can also be edited through an in-game screen.
  • 🚫 Non-interfering — Never touches vanilla's spawn system.

Open Parties and Claims compatibility

If Open Parties and Claims is installed and `openPartiesAndClaimsSupport` is enabled, Undead Riders checks OPAC claim settings before spawning a horseman.

Claims that have hostile natural spawning disabled, for example through OPAC's "allow hostile spawn" setting, will block Undead Riders natural spawns in that claimed area.

🔄 Commands

Both commands require OP.

/undeadriders reload - Reloads the config from disk without a server restart.
/undeadriders info - Shows enabled/disabled status, spawn rates, and current caps in chat.
