Description

Skycreeps

Skycreeps is a NeoForge mod for Minecraft 1.21.1 inspired by the Seacreeper / Seacreep mod, adding a new creeper relative adapted for life in the upper reaches of the Overworld.

Rather than wandering around on the ground, Skycreeps circle high-altitude areas, perch on cliffs and treetops, hunt animals, and generally try to stay out of reach.

They are not mindlessly aggressive. A wild Skycreep prefers to flee when approached, but persistent players may provoke a beak attack, retreat, and eventually an explosive dive.

Features

Skycreeps

Skycreeps can:

  • Patrol the skies at high altitude
  • Perch on cliffs and trees
  • Hunt rabbits, pigs, sheep, and goats
  • Carry prey into the air
  • Become much more vulnerable while carrying an animal
  • Flee from cats
  • Become charged by lightning
  • Peck players as a warning before escalating
  • Use an explosive dive as a last resort
  • Drop Skycreep Feathers, Gunpowder, and Beaks

They naturally spawn in the Overworld only.

Insomnia Encounters

Going too long without sleep eventually makes the skies much less friendly.

After 30 in-game days without sleeping, enraged Skycreeps can begin spawning near the player during the same nighttime conditions used for phantom encounters.

Unlike ordinary wild Skycreeps, these variants:

  • Can attack at any elevation
  • Immediately target the sleepless player
  • Dive much more aggressively
  • Explode on impact

Sleeping resets the threat.

Beak Culverin

Skycreep Beaks can be used to craft the Beak Culverin, a heavy crank-operated fantasy ranged weapon.

Its behavior depends on the ammunition loaded into it.

Normal Arrows

Normal arrows are fired as slow, heavy shots:

  • High velocity
  • High individual damage
  • Low rate of fire
  • One shot every few seconds

Skyshot Arrows

Skyshot Arrows are crafted using Skycreep Feathers and turn the Culverin into a rapid-fire weapon:

  • Very high fire rate
  • Lower damage per projectile
  • Minimal projectile drop
  • Designed for sustained fire against airborne targets

The result is somewhere between a medieval hand cannon and a crank-operated fantasy machine gun.

Sky TNT

Skycreeps also adds three specialized TNT blocks.

Featherburst TNT

A fragmentation explosive that releases a radial burst of fast-moving Skyshot projectiles after detonation.

Useful for:

  • Area denial
  • Anti-air attacks
  • Dense groups of mobs
  • General poor decision-making

Storm TNT

An electrical explosive that:

  • Calls down lightning
  • Disrupts nearby flying entities
  • Interferes with shields
  • Applies combat debuffs
  • Causes a destructive blast

Cloud TNT

A mostly non-destructive airburst that:

  • Launches nearby entities upward
  • Pushes them outward
  • Resets fall distance
  • Grants temporary Slow Falling

It can be used offensively, defensively, or as improvised mobility.

Requirements

  • Minecraft 1.21.1
  • NeoForge 21.1.x
  • GeckoLib 4

GeckoLib is a required dependency.

Compatibility

Skycreeps is designed to work in normal survival worlds, but the mod is especially suited to:

  • Elytra-heavy gameplay
  • PvPvE modpacks
  • Aerial exploration
  • Create: Aeronautics-style modpacks
  • Worlds where the upper sky could use more danger

Known Issues

  • In third-person, the Beak Culverin may not visually align perfectly with the direction of fired arrows after completing its loading animation.
  • This is currently a visual issue only; projectile direction and weapon behavior are unaffected.
