Genetically Modified Monsters

The mod introduces mutated monsters that are built to push a player's limits. Familiar mobs can gain mutations that alter their attacks and movement, so a fight that once followed a known pattern may not. Several mutated Creepers leap multiple blocks high, scale walls and vertical surfaces, and move faster with better pathfinding, which removes many of the safe hiding spots players normally rely on.

Some variants explode with stronger blasts, including charged forms whose explosion reaches farther, which makes close-range fights more dangerous. Other variants stay silent until they strike, so the usual audio warning is absent. Once a mutated Creeper locks onto a player it can be hard to shake, and the adaptive AI dodges, repositions, avoids hazards and pursues players during combat.

The mod runs on the client and the server, so both need it installed.
