I would suggest this mod to ftb of network servers This mod make the battles more fun, because late game armor like Quantum makes the fights boring this will help "This mod randomly imbues spawning Living Things in the World with Diablo-style random Enchantments, making them much harder and much more rewarding to kill. They also drop the quadruple amount of xp and a random enchanted item."
We do not create the modpacks. There for the request needs to go to the creators at feed-the-beast.com
doesnt really change the game/battles all that much in the days of hexxit the were excedingly easy to take out with a rapier and thief/rouge(havent played in a while not sure which it is) armor, really only affects early-game
