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.
