This mod pack includes mods that cover multiple areas of minecraft.
The first area EXPLORATION: This modpack includes a few mods called BetterEnd, Biomes O' Plenty, Repurposed Structures, and small ships. All of these mods improve biome generation, and structure generation (except for the small ship mod that includes a few variations of boats that help you explore faster) most of the mods include a few base biomes with more variations of that biome making a lot of new biomes to explore.
The second area MOBS: This modpack has Alex's Mobs, Mowzie's Mobs, and Spiders 2.0. Those mods include many mobs such as Gorillas, giraffes, and Barako(a antasy mob in the Mowzie's Mobs mod). The spiders 2.0 mod includes better spider animations.
The third area EXTRAS: This modpack has Better Weather, Comforts, and Dynamic Surroundings. The Better weather mod includes things like Blizzards, Rain storms, and acid rain. The comfort mod includes a sleeping bag, and a Hammock(which lets you sleep through the day). Dynamic Surroundings just have better sounds.
Also citadel is another mod in this modpack which includes technical improvements for most of the mods.
All of these mods make your experience playing minecraft better, giving you more mobs to see, more bosses to slay, and more materials to build with.
