Shadowforms
Shadowforms reshapes how mobs spawn and behave in dark places, adding shadow variants that appear where light level is 0 and a datapack-driven set of structures, drops and music.
What it does
Shadowforms is a server-side mechanic that turns mobs in low-light areas into shadowforms, a darker variant with its own behavior. Some mobs become stronger shadows that are faster and tougher than regular shadowforms, and these do not weaken with light. Killing a strong shadow can yield a Blackened Heart, a block used in later crafting.
The mod adds a structure named Ancient Villages and a biome named Smog, along with brews, athames, orbs, darkness-themed enchantments and other equipment. A bundled datapack includes a music disc built around Danse Macabre and several other classical pieces used as background tracks and ambience. The content is centered around the shadowform mechanic.
Shadowforms is released under the MIT License. Only the server needs the mod installed, so players join without it. Files cover game versions 1.21.6 – 26.2 for Fabric, Forge, NeoForge and Quilt, and the mod is also offered as a data pack for server platforms.
Key features
Light-based shadowforms
Mobs in areas with light level 0 can turn into shadowforms, which behave differently from their regular forms.
Strong shadows
Some mobs become strong shadows that move faster and are harder to fight, and they ignore light weakening.
Blackened Heart
Strong shadows drop a Blackened Heart block when killed, which is used in the mod's crafting content.
Brews, athames and enchantments
Shadow brews, athames, orbs and ancient enchantments add gear and effects tied to the darkness theme.
Ancient Villages and Smog
Ancient Villages generate as a structure and Smog as a biome, both placed in the world during generation.
