This addon adds up to 1000 new mobs to your world, each with varying speed, damage, health, loot, texture, and spawn rate. This addon will spice up your survival world and add more challenging enemies to face.
The mobs have low spawn rate, but together it adds up. The less amount of mobs you have means less variety, but more vanilla mob spawning. This addon is not very resource-intensive, but it takes a while to download and set up due to the textures.
