Elemental Creepers: Refabricated

The mod adds more than ten creeper variants to the world, each tied to an element such as water, fire, earth, air, ice, magma or hydrogen. Each variant spawns in its own type of biome, so a water creeper appears near oceans and other water-related biomes while a fire creeper appears in hot biomes like deserts, mesas and savannas. Their explosions leave different effects behind, from a dirt mess or a snow layer to fire and lava fountains.

Killing an elemental creeper yields an element item that can be crafted into an elemental TNT, which replaces the vanilla gunpowder recipe. The spawn rate, the explosion radius and the ability to spawn each creeper individually can be changed in the configuration. The mod is a Fabric port of a famous mod, modernized with some liberties taken by its author, and it requires Fabric API. It runs on client and server, so the server and every player need it, and the code is open source under the MIT License, with files for 1.18.1 – 1.20.1.
