A mod that aims to make combat encounters in Minecraft more varied and interesting with the introduction of several new mobs. The mod is in continual development, consistently being updated by Nekomaster with all manner of creatures to freshen up your combat experience.
I highly suggest installing In Control! or Bad Mobs to disable or limit the spawning of mobs you don't like. You could also use Mobs Properties Randomness if you wanted to weaken or buff certain mobs too! Whilst all the mobs can be dealt with using only vanilla mechanics, it'd be far more fun if you also installed other mods that implemented more complex battle mechanics too, including Combat Roll and Shield Expansion.
A Zombie that runs fast! When attacked, becomes stunned for a moment before resuming its assault.
A Zombie that hits hard! When attacked, briefly gains a speed boost to rush you down with. Back-peddle for your life!
Little undead guy doesn't burn in sunlight, and who loves flesh so much, will cannibalise it's fellow Zombie if no humans are nearby!
Can be tamed with Rotten Flesh, and will gain more and more health on each kill it earns.
Rarely drops the Meathead, a helmet that gives the player temporary Strength for each kill they earn.
The dreadful bloodsucker of the underground, Vampires are exceedingly dangerous due to their versatility. Upon biting a victim, they regenerate some of their health and have inflict both momentary Blindness, and the new Bitten effect, which will burn whoever has it under daylight - And if the bite victim is a mob... They're doomed to become a Vampire too, just like their aggressor. (They will target Zombies when ground-based, even if a player is nearby, specifically to create reinforcements!) They also inflict blindness, before running away. If hurt enough, they may chose to engage in flight mode, in which they'll rush you down when they're not floating about idly. In moments of desperation, they may turn into the Biter, a smaller, more erratic version of themselves. If they do this and return to normal, they'll have regenerated all their health. Take them out whilst they're small to avoid that! If they get burnt, they'll quickly combust and explode. Rarely drops the Headbiter, a helmet that gives the player temporary Regeneration for each kill they earn.
