When a remake is better than the original
Reputation ranks
Ranks only ever go up; points can drop but your rank stays.
About reputation ranksWhile Mutant Creatures was the inspiration, Mutant Monsters takes the concept to a better, modern, higher level.
Mutant Monsters are the mobs that I almost always run from or try to sneak by. Most modded hostile mobs are fine, but these are absolutely terrifying. Even fully geared, it's better to fight strategically, and allows for much more engaging PvE (and PvP if multiplayer) combat.
I have screenshots upon screenshots of memorable fights I've had with mutant monsters: ambushes from massive, 4-legged creepers, world-destroying fights between a mutant skeleton and a mutant creeper, and mutant endermen blocking the exit to my cave.
I highly recommend this mod. Tune the config, make the spawn rates slightly lower, and enjoy a difficult fight and engaging challenge to your modded world!
