Just wanting a mod to be able to adjust things for difficulty, things like each different enemy, movement speed, attack damage, speed and reach. Control the spawning pools so If I wanted plains biome enemies to naturally spawn in meadows after a certain day / boss is killed. Control enemy spawn rates. Control what mobs consider enemies so they only attack the player not eahcother Since we are controlling mob spawning also include the animals as well so we can control the frequency and amount of animals that spawn in the wild. Combine this with the mod Event Enhancer that allows you to adjust events frequency and you can have a nice package.
