Mutant Mobs
by rolikdoesmc
Mutant Mobs, a Forge mod for 1.12.2 by rolikdoesmc, adds mutated versions of vanilla mobs made from a Toxic Waste serum and a spider-based Chemical Z mixture.
What it does
The mutant creatures keep the properties of the vanilla spider they are based on, and they drop the same loot. Each one is built from a particular ingredient set, which makes the serum the central mechanic. The Spider Pigman, for example, has 160 health, deals 6 damage per hit and leaps around its opponents every 500 to 700 ticks, spawning baby spiders during the fight. At night it heals 3 health every 400 ticks. It takes no fall damage, including in its spider jockey variation.
When a mutant dies it can spawn a horde of babies, and each mutant has a 1% chance to spawn in biomes such as forest, desert and plains. The mod also adds the toxic waste and radiation-themed items that players craft the serum from. The author describes the serum as the deadliest ever made, and says the mutants were an accidental result of a failed mixture. The mod is a Forge mod for 1.12.2, and it runs on client and server, so the server and every player need it. Only Forge files exist, released on 2024-02-14, and the code is under All rights reserved, so the mod is not open source.
Key features
Spider Pigman
A mutant that combines spider behavior with a pig-like form, leaping at opponents and calling baby spiders into the fight.
Inherited spider traits
Mutants keep the health, damage, movement and loot of the vanilla spider they come from, with variations for the jockey form.
Horde death
Some mutants spawn a group of babies when they die, so a defeated mob can still threaten the player.
Natural spawns
Mutants have a 1% chance to spawn in forest, desert and plains biomes, with the serum ingredients adding more creatures over time.
